0:02:53 > 0:02:58- In no time at all, she increases her - pace and leaves Lowri to race alone.
0:02:58 > 0:03:01- I've been racing - for two and a half hours.
0:03:02 > 0:03:06- I started with Diane - and she offered me a lot of advice.
0:03:06 > 0:03:10- She's an old hand - at competing in these races...
0:03:10 > 0:03:14- ..and is world famous - for her Arctic achievements.
0:03:14 > 0:03:16- I feel fine.
0:03:18 > 0:03:21- It's important for me - to drink all day.
0:03:21 > 0:03:25- I must also protect my skin.
0:03:25 > 0:03:31- The frosty chill attacks - within seconds of removing my mask.
0:03:32 > 0:03:37- The mask is constantly misting up - so I can't see where I'm going...
0:03:37 > 0:03:42- ..but it's an important piece - so I'll wear it as much as possible.
0:03:53 > 0:03:57- After three days of preparing - for this race in Canada...
0:03:58 > 0:04:02- ..there's a wonderful camaraderie - amongst the competitors.
0:04:02 > 0:04:05- We all have different tactics.
0:04:05 > 0:04:10- For example, - I've never raced without sleep...
0:04:10 > 0:04:15- ..so I don't know how I'll cope - with the sleep deprivation.
0:04:16 > 0:04:18- Whereas, the boys behind me - are soldiers...
0:04:19 > 0:04:23- ..who are trained to keep going - all through the night.
0:04:23 > 0:04:28- They will maintain a slow pace - with as little sleep as is possible.
0:04:28 > 0:04:30- Everyone is different.
0:04:31 > 0:04:37- We are hear to learn - and push our personal boundaries.
0:04:37 > 0:04:40- We'll have to wait - and see what happens.
0:04:40 > 0:04:42- Dear, dear!
0:04:44 > 0:04:46- It's certainly a great start...
0:04:46 > 0:04:49- ..but the weather is about - to cause Lowri some problems.
0:04:50 > 0:04:54- The temperature has fallen - to -30 degrees Celsius.
0:04:54 > 0:05:00- Believe it or not, it is relatively - mild for the time of year.
0:05:00 > 0:05:03- It's a bit of a dilemma for me.
0:05:04 > 0:05:07- I'm overheating - and I'm only wearing two layers.
0:05:07 > 0:05:10- It's unbelievable in this weather.
0:05:10 > 0:05:14- If I remove one layer...
0:05:14 > 0:05:19- ..my neck will be completely exposed - to the elements.
0:05:20 > 0:05:22- This is an eight-day race...
0:05:23 > 0:05:27- ..and I don't want to get frostbite - on Day 1!
0:05:27 > 0:05:31- If the body gets too warm, it will - sweat, which can be very dangerous.
0:05:32 > 0:05:37- The sweat will freeze on the body - and this will lead to frostbite.
0:05:40 > 0:05:42- Lowri could slow down...
0:05:42 > 0:05:47- ..but opts to remove - a layer of thick clothing.
0:05:48 > 0:05:54- When you remove a layer of clothing, - the body cools down very quickly.
0:05:55 > 0:06:00- I'm going to change this top...
0:06:00 > 0:06:03- ..and replace it with a jacket.
0:06:03 > 0:06:06- Gosh, my body has got so cold.
0:06:07 > 0:06:10- Dear, dear, dear, dear. - Oh, it's cold!
0:06:10 > 0:06:15- I really hope that I'm not making - a stupid decision...
0:06:16 > 0:06:19- ..and ruining my chances.
0:06:21 > 0:06:26- Ironically, during the break of less - than a minute to change clothes...
0:06:26 > 0:06:30- ..Lowri has cooled down, - so she needs to run to warm up.
0:06:40 > 0:06:44- They finally reach - the Arctic Circle.
0:06:44 > 0:06:48- Scotland's David Jorgensen is first - and Lowri is in fifth place.
0:06:48 > 0:06:53- Some 24 miles have been completed - in 6 hours and 39 minutes.
0:06:53 > 0:06:57- The unfortunate incident of - overheating is preying on her mind.
0:06:57 > 0:07:01- She consults the doctor of the race - when she arrives.
0:07:01 > 0:07:03- My back was sweating.
0:07:03 > 0:07:05- My back was sweating.- - Was it frozen?
0:07:05 > 0:07:07- It's done now. Don't worry about it.
0:07:07 > 0:07:11- The doctor is happy and Lowri - takes comfort in his words.
0:07:11 > 0:07:14- She made the right decision.
0:07:14 > 0:07:19- After a 20-minute break, - Lowri is back on form.
0:07:21 > 0:07:26- I'm totally humbled to be - standing here, surrounded by nature.
0:07:26 > 0:07:31- There isn't any pollution, - just sheer beauty.
0:07:32 > 0:07:38- I'm moving on to the next stage - which is about 45 miles in total.
0:07:38 > 0:07:43- They say that this next stage - is the most challenging.
0:07:44 > 0:07:48- The next stage - to James Creek is 45 miles.
0:07:48 > 0:07:52- Competitors have the option - of taking a break at Rock River.
0:07:54 > 0:07:57- It's 4.00pm - on the first afternoon of the race.
0:07:57 > 0:08:00- Lowri has been competing - since 9.00am.
0:08:01 > 0:08:04- She has already completed - an entire marathon...
0:08:04 > 0:08:09- ..but this is just the start - of the world's toughest ultra race.
0:08:09 > 0:08:13- Over 320 miles remain!
0:08:14 > 0:08:20- I'm currently gazing - at this stunning sunset.
0:08:20 > 0:08:23- It's wonderful.
0:08:23 > 0:08:28- However, this experience is filling - me with bittersweet emotion...
0:08:28 > 0:08:33- ..because it means that - I'm about to face my first night...
0:08:33 > 0:08:36- ..on the Dempster Highway.
0:08:36 > 0:08:38- It fills me with fear...
0:08:39 > 0:08:45- ..because I know - that Wright Pass is next.
0:08:45 > 0:08:50- Apparently, - it's going to be painful.
0:08:50 > 0:08:55- It is going to be long, - windy and cold.
0:08:56 > 0:09:02- I hope to complete this stage - in the dark...
0:09:02 > 0:09:06- ..so that I cannot see - what lies ahead of me.
0:09:17 > 0:09:20- Despite her fears, - Lowri steps up her pace...
0:09:20 > 0:09:25- ..in order to reach the checkpoint - at Rock River as soon as possible.
0:09:26 > 0:09:31- She catches the experienced runners - ahead of her but receives bad news.
0:09:31 > 0:09:37- Diane, who accompanied Lowri earlier - is injured and is forced to retire.
0:09:38 > 0:09:39- I'm so sorry, Diane.
0:09:39 > 0:09:41- I'm so sorry, Diane.- - Don't worry.
0:09:41 > 0:09:45- The hard surface has irritated - an old ankle injury.
0:09:45 > 0:09:51- It's worrying to see an experienced - competitor retiring at this stage.
0:09:51 > 0:09:55- This race is baring its teeth.
0:09:56 > 0:10:02- I don't want to stay here for too - long as I feel like I'm in the zone.
0:10:03 > 0:10:07- I'll have something hot - to warm up the body...
0:10:08 > 0:10:11- ..and give me some energy - so that I can continue.
0:10:16 > 0:10:18- I've seen Diane.
0:10:19 > 0:10:22- I'm disappointed for her.
0:10:22 > 0:10:27- I was hoping that - she would break the race record...
0:10:30 > 0:10:32- ..but it wasn't meant to be - this year.
0:10:33 > 0:10:36- All of the competitors - decide to sleep at this point.
0:10:36 > 0:10:40- They have been racing - for over 15 hours non-stop.
0:10:40 > 0:10:43- However, Lowri has other ideas.
0:10:44 > 0:10:47- Unlike the other runners, - Lowri continues racing...
0:10:47 > 0:10:50- ..all through the night!
0:10:51 > 0:10:54- The training session - from a few months ago at Brecon...
0:10:54 > 0:10:59- ..where I ran the Brecon Ultra - before running home to Swansea...
0:11:00 > 0:11:02- ..was useful training - for this moment.
0:11:02 > 0:11:06- I did that session - for both my physical...
0:11:06 > 0:11:09- ..and psychological wellbeing.
0:11:10 > 0:11:12- This is the time - for me to dig deep.
0:11:13 > 0:11:18- There's 20 miles to the next - checkpoint at James Creek.
0:11:18 > 0:11:23- I've done 100 miles in the past - and I can do these 20 miles now.
0:11:23 > 0:11:29- It might take ten hours, - if not longer, but I'll do it.
0:11:29 > 0:11:35- I'll be getting into my sleeping bag - in the morning...
0:11:35 > 0:11:37- ..hopefully!
0:11:41 > 0:11:43- Is this a wise tactic?
0:11:43 > 0:11:47- How will Lowri be - at the break of dawn?
0:11:50 > 0:11:50- .
0:11:53 > 0:11:53- 888
0:11:53 > 0:11:55- 888- - 888
0:11:56 > 0:12:00- Lowri Morgan has started - the challenge of her life.
0:12:01 > 0:12:04- It's the 6633 Ultra race - in the Arctic Circle.
0:12:04 > 0:12:08- She has already made - one brave decision.
0:12:15 > 0:12:20- Lowri has been on her feet for 15 - and a half hours on the first day.
0:12:20 > 0:12:24- She has already completed 48 miles.
0:12:24 > 0:12:28- Instead of resting at Rock River - with the other runners...
0:12:28 > 0:12:32- ..Lowri chose to continue racing - through the night.
0:12:33 > 0:12:37- I've been climbing for five hours.
0:12:40 > 0:12:46- And I'm pulling about 20 kilos.
0:12:48 > 0:12:49- Oh!
0:12:51 > 0:12:54- I hope this is a downhill section.
0:12:56 > 0:12:57- Please.
0:12:59 > 0:13:03- And this fatigue is killing me.
0:13:05 > 0:13:10- Lowri parted from the others to - cross the Northwest Territories...
0:13:11 > 0:13:14- ..so the race organizer, - Martin Like from Brecon...
0:13:14 > 0:13:17- ..joins her to ensure her safety.
0:13:17 > 0:13:19- There's no stopping Lowri...
0:13:19 > 0:13:24- ..despite the fact that she has been - on her feet for 20 hours.
0:13:26 > 0:13:30- As dawn breaks, - Lowri is still racing.
0:13:30 > 0:13:34- It's difficult to admire - the Richardson Mountains...
0:13:34 > 0:13:38- ..in temperatures of -60 - degrees Celsius in the biting winds.
0:13:38 > 0:13:43- This is the highest part of the race - at over 6,000 feet above sea level.
0:13:43 > 0:13:48- It's twice the height of Snowdon - and the coldest stage so far.
0:13:49 > 0:13:51- Having beaten the mountains...
0:13:51 > 0:13:55- ..Lowri reaches James Creek - at 9.30am...
0:13:56 > 0:13:59- ..and is welcomed by Kevin, - a race steward.
0:13:59 > 0:14:02- James Creek - is not a five-star hotel...
0:14:02 > 0:14:06- ..but a storage area - for the council's snow machinery.
0:14:06 > 0:14:12- The first 24 hours are over - and I'm absolutely exhausted.
0:14:13 > 0:14:16- Martin, the race director...
0:14:16 > 0:14:22- ..warned us that the first 70 miles - would be physically challenging...
0:14:22 > 0:14:25- ..and a shock to the system.
0:14:25 > 0:14:27- He wasn't telling lies!
0:14:29 > 0:14:34- I'm concerned that I'm the only one - who has done the 70 miles.
0:14:34 > 0:14:36- Everybody else stayed at Rock River.
0:14:37 > 0:14:42- I don't know if I've taken a risk - by doing that...
0:14:42 > 0:14:47- ..but I was feeling well - at Rock River so I went for it.
0:14:49 > 0:14:53- Tired or not, Lowri - must prepare her own meal.
0:14:53 > 0:14:59- After essential maintenance to the - pulk and her feet, she falls asleep.
0:15:05 > 0:15:09- One would expect Lowri - to sleep for a lifetime...
0:15:09 > 0:15:14- ..but after two hours, she bids - farewell to England's David Smale...
0:15:15 > 0:15:18- ..a competitor who arrived - while she was asleep.
0:15:18 > 0:15:20- Good morning.
0:15:21 > 0:15:24- On the second day of the race...
0:15:24 > 0:15:29- ..Lowri faces 47 miles along the - Dempster Highway to Fort McPherson.
0:15:29 > 0:15:33- The Dempster is named - after the Welshman, Jack Dempster.
0:15:33 > 0:15:36- He was a Mountie - in the Canadian police...
0:15:36 > 0:15:41- ..after he emigrated to the country - over a century ago.
0:15:43 > 0:15:46- I'm in a brilliant position - and loving it.
0:15:46 > 0:15:50- The landscape - is totally breathtaking.
0:15:52 > 0:15:56- I'm a person - who tends to feel homesick...
0:15:57 > 0:16:00- ..but I don't feel lonely at all - out here.
0:16:04 > 0:16:07- I'm so lucky to be here.
0:16:15 > 0:16:19- Lowri has completed a third - of the journey to Fort McPherson...
0:16:20 > 0:16:21- ..and is making good time.
0:16:22 > 0:16:26- A few of the other competitors - are yet to reach James Creek.
0:16:26 > 0:16:29- The Australian, Tim Garrett, - is in high spirits...
0:16:30 > 0:16:32- ..despite struggling with his pulk.
0:16:33 > 0:16:37- # If I could walk 500 miles... #
0:16:37 > 0:16:40- As the sun sets and night falls...
0:16:41 > 0:16:46- ..the fatigue and strain of this - race is taking its toll on Lowri.
0:16:47 > 0:16:51- I've been racing for 40 hours...
0:16:51 > 0:16:54- ..with only two hours of sleep.
0:16:54 > 0:16:57- I'm struggling now.
0:16:59 > 0:17:02- I've been having hallucinations.
0:17:02 > 0:17:07- I'm seeing images in the snow - formations and it isn't very nice.
0:17:07 > 0:17:10- Some claim hallucinations...
0:17:11 > 0:17:16- ..are the mind's way - of keeping the body awake.
0:17:18 > 0:17:21- Sleep is what I need at the moment.
0:17:22 > 0:17:25- The heels of my feet are bruised.
0:17:25 > 0:17:30- Every time I take a step, - I get this shooting pain.
0:17:30 > 0:17:34- Walking at night - causes me such heartache...
0:17:34 > 0:17:38- ..because it gets cold - and it gets lonely.
0:17:39 > 0:17:41- The wind picks up.
0:17:42 > 0:17:48- I'm starting to question whether - or not I can complete the 350 miles.
0:17:48 > 0:17:51- I'm not even a third - of the way there yet.
0:17:52 > 0:17:56- There are voices in my head - planting seeds of doubt.
0:17:56 > 0:18:00- Maybe I went too quickly - at the start of the race.
0:18:00 > 0:18:02- Was I overly confident?
0:18:02 > 0:18:08- I'm experiencing some very negative - thoughts and emotions at the moment.
0:18:11 > 0:18:14- Lowri is not the only one - feeling the strain.
0:18:14 > 0:18:17- The race has claimed - its second competitor.
0:18:17 > 0:18:20- England's Mike Buss - has eight world records.
0:18:20 > 0:18:24- He was exhausted a few miles - after leaving James Creek...
0:18:25 > 0:18:30- ..and the organizers had to lift him - out of his bivvy on the roadside.
0:18:30 > 0:18:33- Ten competitors remain.
0:18:39 > 0:18:41- Lowri is still racing.
0:18:41 > 0:18:47- She crosses a frozen river in - temperatures of -30 degrees Celsius.
0:18:48 > 0:18:51- She reaches the Gwich'in country, - the local Indians...
0:18:51 > 0:18:55- ..and Fort McPherson that - has a population of about 800.
0:18:55 > 0:18:59- Lowri is the first to reach the - school where shelter is provided.
0:19:00 > 0:19:02- I can't wait to go to bed.
0:19:02 > 0:19:05- It isn't very luxurious...
0:19:05 > 0:19:10- ..but I've been thinking about this - sleeping bag for the last 18 hours.
0:19:10 > 0:19:12- Those thoughts kept me going.
0:19:13 > 0:19:17- I'm looking forward to sleeping.
0:19:17 > 0:19:19- Really.
0:19:19 > 0:19:23- It's been very difficult today.
0:19:24 > 0:19:25- Erm...
0:19:26 > 0:19:31- It was painful both emotionally, - physically and mentally.
0:19:32 > 0:19:37- I keep thinking that I'm only a - third of the way through this race.
0:19:42 > 0:19:46- I've had a good - six hours of sleep...
0:19:46 > 0:19:50- ..despite the fact that someone - in this hall was snoring.
0:19:50 > 0:19:54- I learnt from my experience - in the Amazon...
0:19:55 > 0:19:57- ..that I should pack some earplugs!
0:19:57 > 0:20:00- I'm happy with that.
0:20:00 > 0:20:05- The only problem is that my legs - are still feeling heavy...
0:20:05 > 0:20:09- ..and the soles of my feet - are very badly bruised.
0:20:10 > 0:20:15- The next two days are meant to be - the most difficult...
0:20:15 > 0:20:21- ..not because of the landscape - but due to the monotony.
0:20:21 > 0:20:25- Even the greatest of competitors - have retired in the next stages.
0:20:26 > 0:20:29- I think this will be - mentally difficult.
0:20:30 > 0:20:34- Lowri is leading - after the first 120 miles.
0:20:35 > 0:20:40- She could stop here. - Seven competitors do just that.
0:20:41 > 0:20:46- However, Lowri, Tony and Matt - opt to face the 350-mile race.
0:20:48 > 0:20:51- The Welsh are the three - remaining competitors in the race.
0:20:52 > 0:20:54- Thank you very much.
0:20:54 > 0:20:57- The arduousness - of this race is legendary.
0:20:57 > 0:21:02- Many of the world's ultra runners - avoid it for this reason.
0:21:04 > 0:21:10- Day 3 sees 38 miles on the Dempster - Highway to Tsiigehtchic.
0:21:10 > 0:21:15- Today, she opts to walk - with Tony Kelly from Abergavenny.
0:21:15 > 0:21:19- They set off at 4.00pm.
0:21:19 > 0:21:22- It's great to chat - to another person...
0:21:22 > 0:21:26- ..instead of having to listen - to the voices in my head...
0:21:27 > 0:21:29- ..that emerge with fatigue.
0:21:29 > 0:21:30- It's nice to have company, Tony?
0:21:30 > 0:21:32- It's nice to have company, Tony?- - Yeah, lovely.
0:21:45 > 0:21:49- We've stopped here for a moment...
0:21:49 > 0:21:54- ..so that we can have a hot drink...
0:21:55 > 0:21:57- ..and some food.
0:21:57 > 0:22:03- I think I'm consuming - about 10,000 calories a day.
0:22:03 > 0:22:05- How much are you eating, Tony?
0:22:05 > 0:22:07- How much are you eating, Tony?- - Not enough.
0:22:08 > 0:22:11- I find it difficult - to eat through the day.
0:22:11 > 0:22:12- Yes, it is hard.
0:22:12 > 0:22:15- Yes, it is hard.- - Yeah. I don't know why.
0:22:15 > 0:22:19- It's so nice to have company. - It makes a world of difference.
0:22:19 > 0:22:24- It boosts the morale - and your spirits.
0:22:24 > 0:22:30- This is completely frozen. I can't - open it so need to defrost it.
0:22:31 > 0:22:35- People have asked me - a number of questions...
0:22:36 > 0:22:39- ..about how I go to the toilet - out here.
0:22:40 > 0:22:44- We were advised to spend - no longer than 30 seconds.
0:22:45 > 0:22:48- That is all the time we have - to go to the toilet...
0:22:48 > 0:22:52- ..before frostbite would kick in.
0:22:56 > 0:23:01- You can't be shy out here.
0:23:01 > 0:23:05- You have to go and then carry on.
0:23:08 > 0:23:11- I miss life's little luxuries - at the moment!
0:23:23 > 0:23:27- Five hours later, - and despite enjoying the company...
0:23:27 > 0:23:30- ..her body is still suffering.
0:23:32 > 0:23:37- Pain disappears over time...
0:23:37 > 0:23:41- ..but success lasts forever.
0:23:41 > 0:23:43- I have to bear that fact in mind...
0:23:44 > 0:23:49- ..during the dark - and difficult times that lie ahead.
0:23:50 > 0:23:55- The difficult 38-mile section from - Fort McPherson to Tsiigehtchic...
0:23:55 > 0:23:59- ..is completed by Lowri and Tony - in 14 hours.
0:23:59 > 0:24:01- They reach suburbia...
0:24:01 > 0:24:06- ..but receive news that the third - remaining runner has dropped out.
0:24:06 > 0:24:09- This race is baring its teeth now.
0:24:09 > 0:24:13- The adrenalin from the start line - is long gone...
0:24:13 > 0:24:17- ..and the reality of the event - is taking hold.
0:24:18 > 0:24:24- The miles are long - and hard on the feet and joints.
0:24:25 > 0:24:30- I've visited parts of my mind that - I don't want anyone else to see.
0:24:30 > 0:24:34- I've been quite depressed, - but it's over now.
0:24:34 > 0:24:39- I'll sleep for four hours, - get up and do the 50 miles tomorrow.
0:24:39 > 0:24:41- It's all part of the game.
0:24:44 > 0:24:46- Lowri isn't halfway there yet...
0:24:46 > 0:24:49- ..but there's a crisis ahead!
0:24:49 > 0:24:50- Oh, no!
0:24:54 > 0:24:54- .
0:24:56 > 0:24:56- 888
0:24:56 > 0:24:58- 888- - 888
0:25:00 > 0:25:03- Lowri is facing the greatest - challenge of her life.
0:25:04 > 0:25:07- It's the 6633 Ultra - in the Arctic Circle.
0:25:07 > 0:25:11- She's about to receive - some distressing information.
0:25:15 > 0:25:17- Day 4...
0:25:17 > 0:25:21- ..and of the twelve competitors who - left Eagle Plains 158 miles ago...
0:25:22 > 0:25:24- ..only two remain.
0:25:25 > 0:25:28- Every competitor - has retired from the race...
0:25:28 > 0:25:32- ..apart from the Welsh contingent, - Tony Kelly and Lowri Morgan.
0:25:36 > 0:25:40- Next, they face the 51 miles - from Tsiigehtchic to Caribou Creek.
0:25:41 > 0:25:44- The Dempster Highway - is now a path of frozen gravel.
0:25:45 > 0:25:49- Lowri and Tony aim to complete - this journey without stopping.
0:25:50 > 0:25:54- The pair must cross the Mackenzie - River which is frozen solid.
0:25:55 > 0:25:56- Conditions are favourable.
0:25:57 > 0:26:02- There's no wind but the temperature - is -25 degrees Celsius.
0:26:08 > 0:26:13- Despite the company, - Lowri is feeling despondent.
0:26:13 > 0:26:18- I'm struggling, because - only Tony and I remain in the race.
0:26:21 > 0:26:26- It's heartbreaking to think that - we're not even halfway there yet.
0:26:27 > 0:26:30- We've completed 175 miles...
0:26:30 > 0:26:35- ..and there are still - 175 miles left.
0:26:36 > 0:26:39- My feet are in tatters.
0:26:40 > 0:26:44- I can't think. I can't speak.
0:26:46 > 0:26:52- I'm experiencing - some very negative emotions...
0:26:52 > 0:26:55- ..and I don't think I can do this...
0:26:55 > 0:26:59- ..but I've given my all - to this challenge.
0:27:00 > 0:27:04- Right, it's up to me. I must - keep going but I feel so frustrated.
0:27:05 > 0:27:08- Just, just carry on going!
0:27:09 > 0:27:15- I need to pull myself together now.
0:27:17 > 0:27:20- I can't let this race beat me.
0:27:20 > 0:27:22- Right, OK.
0:27:24 > 0:27:26- Right.
0:27:28 > 0:27:31- There are 40 miles left...
0:27:32 > 0:27:36- ..before I can get about - three hours sleep.
0:27:36 > 0:27:39- Then there will be 30 miles...
0:27:40 > 0:27:41- Oh, it's never-ending.
0:27:42 > 0:27:47- The monotony of it all - is playing havoc with my mind.
0:27:47 > 0:27:50- My feet are in so much pain.
0:27:50 > 0:27:52- I can cope with the muscle pain...
0:27:52 > 0:27:57- ..but the pain in my feet - is shooting up my legs.
0:27:57 > 0:28:02- But I'm lucky - to be going with Tony.
0:28:02 > 0:28:05- We spur each other on.
0:28:06 > 0:28:08- It's an extremely - emotional experience.
0:28:09 > 0:28:12- Sadness becomes elation - in the blink of an eye.
0:28:12 > 0:28:17- The conditions and pulk mean every - step is slower and more difficult.
0:28:17 > 0:28:22- In Wales, Lowri can complete - a marathon in 3 hours, 15 minutes.
0:28:22 > 0:28:25- In the Arctic, - it takes three times longer...
0:28:25 > 0:28:29- ..and the mind - struggles to comprehend this.
0:28:36 > 0:28:40- Suddenly, - fate deals Tony an almighty blow.
0:28:41 > 0:28:44- Unfortunately, - Tony has had a puncture.
0:28:45 > 0:28:47- He's been dragging the pulk...
0:28:47 > 0:28:52- ..for about seven miles or so, - I think.
0:28:52 > 0:28:55- As a result, he's injured his foot.
0:28:55 > 0:28:59- He isn't comfortable - with deconstructing...
0:28:59 > 0:29:03- ..and rebuilding the pulk - in these conditions.
0:29:03 > 0:29:09- I'm upset for Tony - because this is strenuous work...
0:29:09 > 0:29:15- ..and I know that this - has upset him quite a bit...
0:29:15 > 0:29:17- ..because we were making good time.
0:29:18 > 0:29:19- It's one of those things.
0:29:19 > 0:29:24- We ran out of snow on the road so - I couldn't drag it on the sleigh.
0:29:27 > 0:29:29- I think it had enough.
0:29:31 > 0:29:35- But apart from that, - we're all good.
0:29:37 > 0:29:41- The pulk has been repaired - and the pair continue...
0:29:41 > 0:29:44- ..but it's obvious - that Tony is limping.
0:29:45 > 0:29:49- They venture into the darkness - but Tony needs to rest.
0:29:49 > 0:29:55- Lowri agrees to stay with him - and the pair sleep outside.
0:29:57 > 0:29:59- Tony was utterly exhausted.
0:29:59 > 0:30:01- As the sun rises an hour later...
0:30:02 > 0:30:07- ..it's apparent that their choice - of site could have proved fatal.
0:30:08 > 0:30:11- When I woke up this morning - and realized where we were...
0:30:12 > 0:30:14- ..I was really annoyed with myself.
0:30:15 > 0:30:17- The choice of location - was complete stupidity.
0:30:19 > 0:30:23- When you've only had - an hour's sleep in 24 hours...
0:30:23 > 0:30:28- ..it's inevitable - that mistakes are going to happen.
0:30:29 > 0:30:32- Tony and I - have separated for a while...
0:30:32 > 0:30:37- ..because we're following - different paces at the moment.
0:30:37 > 0:30:41- However, I know that I need - more sleep than he does.
0:30:42 > 0:30:47- It's our intention - to meet at the next checkpoint...
0:30:47 > 0:30:51- ..and start the next stage together.
0:30:52 > 0:30:55- We'll cross that finishing line.
0:30:57 > 0:30:59- Welsh competitors together.
0:30:59 > 0:31:01- Well, that's the aim!
0:31:07 > 0:31:08- It's so picturesque.
0:31:08 > 0:31:12- It's a privilege to be here.
0:31:13 > 0:31:18- There's something spiritual - about the place.
0:31:21 > 0:31:26- I'm not an emotional person, but - I'm full of emotion at the moment.
0:31:43 > 0:31:48- As she completes - the 51 miles to Caribou Creek...
0:31:48 > 0:31:51- ..Lowri is welcomed - by her fellow competitors.
0:31:51 > 0:31:52- Go, Lowri.
0:31:53 > 0:31:55- She's incredible.
0:31:56 > 0:32:02- Lowri's performance and perseverance - is admired by everyone in the race.
0:32:02 > 0:32:05- They all want to see her succeed.
0:32:07 > 0:32:11- Her feet are badly bruised, - so she cools them in the snow...
0:32:11 > 0:32:16- ..before David Smale, who retired - from the race after 120 miles...
0:32:17 > 0:32:21- ..relieves the pain of her blisters - with a needle!
0:32:28 > 0:32:32- But, Lowri receives some bad news.
0:32:32 > 0:32:35- It's bad news, Lowri. Tony's out.
0:32:35 > 0:32:37- It's bad news, Lowri. Tony's out.- - Oh, no.
0:32:42 > 0:32:47- After Lowri left Tony, his - energy levels dropped dramatically.
0:32:47 > 0:32:50- He sat down - to rest on the roadside...
0:32:50 > 0:32:54- ..but failed to get up - to continue the race.
0:32:57 > 0:32:59- It's a bittersweet feeling.
0:33:07 > 0:33:10- There are 150 miles - left to complete...
0:33:11 > 0:33:14- ..in 48 hours.
0:33:16 > 0:33:18- Day 5.
0:33:18 > 0:33:22- There are 30 miles from Caribou - Creek to the new town of Inuvik...
0:33:22 > 0:33:25- ..the administrative centre - for the region.
0:33:25 > 0:33:29- There's only one runner - left in the race.
0:33:29 > 0:33:33- This is a very strange feeling...
0:33:34 > 0:33:37- ..and it's quite unnerving.
0:33:37 > 0:33:39- I'm the only one left.
0:33:39 > 0:33:44- The race is only continuing - because I'm still competing.
0:33:46 > 0:33:51- I'm very nervous, but that's how - it is so I must keep going.
0:34:05 > 0:34:07- About a fortnight ago...
0:34:07 > 0:34:13- ..I was complaining - that I was tired of all this work...
0:34:13 > 0:34:16- ..of jumping into the bivvy...
0:34:16 > 0:34:20- ..eating the dehydrated food - and so on.
0:34:20 > 0:34:25- By now, the pulk and its contents - are an integral part of my life.
0:34:26 > 0:34:31- I love my sleeping bag - and I even like the food.
0:34:31 > 0:34:36- They are my shelter. - They provide energy.
0:34:36 > 0:34:39- These factors drive me on.
0:34:41 > 0:34:45- The scenery in the Arctic Circle - is magnificent at times...
0:34:45 > 0:34:49- ..but the journey from Caribou Creek - to Inuvik is very monotonous.
0:34:52 > 0:34:57- Lowri strides on - and finds a good rhythm.
0:34:58 > 0:35:03- As night falls and the temperature - drops to -30 degrees Celsius...
0:35:04 > 0:35:06- ..she's totally exhausted.
0:35:06 > 0:35:10- She welcomes the company of David - Smale who offers some encouragement.
0:35:13 > 0:35:16- The stage is difficult.
0:35:19 > 0:35:24- The walking sticks take her weight - to ease the pressure on her legs.
0:35:24 > 0:35:29- She's literally - sleeping on her feet.
0:35:35 > 0:35:38- But, she finds the strength - to carry on...
0:35:38 > 0:35:42- ..and miraculously reaches Inuvik...
0:35:42 > 0:35:44- ..though her emotions are in shreds.
0:35:55 > 0:35:57- I can't stop crying.
0:35:57 > 0:36:00- People are so kind.
0:36:02 > 0:36:08- David walked with me - for the last 15 miles today.
0:36:08 > 0:36:13- He gave up a night's sleep - to help me through this.
0:36:14 > 0:36:18- It's just so humbling.
0:36:22 > 0:36:25- I don't know why people - are willing to do it...
0:36:25 > 0:36:29- ..but I am so grateful to them.
0:36:30 > 0:36:31- There you are.
0:36:32 > 0:36:33- I've done...
0:36:34 > 0:36:37- I'm going to bed now...
0:36:38 > 0:36:42- ..but I'm trying to relieve - the pressure in my bones and joints.
0:36:45 > 0:36:48- Lowri is exhausted as she leaves - the Dempster Highway...
0:36:49 > 0:36:51- ..to face the famous Ice Road...
0:36:52 > 0:36:55- ..but how will she cope?
0:36:55 > 0:36:58- I'm going to fail here. I know I am.
0:37:01 > 0:37:01- .
0:37:03 > 0:37:03- 888
0:37:03 > 0:37:05- 888- - 888
0:37:08 > 0:37:13- Following an eight-hour break - at Inuvik for her body to recover...
0:37:14 > 0:37:16- ..Lowri is back in the race.
0:37:16 > 0:37:19- But will she finish in time?
0:37:25 > 0:37:26- Give it stick!
0:37:26 > 0:37:29- Give it stick!- - CHEERING
0:37:31 > 0:37:34- Day 5 is a 70-mile stage...
0:37:34 > 0:37:39- ..from Inuvik to Swimming Point, - the penultimate checkpoint.
0:37:42 > 0:37:46- She has left the Dempster Highway - and is now on the famous Ice Road.
0:37:46 > 0:37:51- Hard, cold ice - from now until the end.
0:37:52 > 0:37:55- Lowri is in tremendous pain.
0:37:55 > 0:37:58- She's also battling - against the clock.
0:37:58 > 0:38:03- In order to succeed, she must reach - Tuktoyaktuk by Saturday morning.
0:38:04 > 0:38:09- She has 72 hours - in which to complete 117 miles...
0:38:10 > 0:38:12- ..or she will be disqualified - from the race.
0:38:13 > 0:38:16- This is truly a race against time.
0:38:19 > 0:38:22- I know - that there are two stages left...
0:38:22 > 0:38:25- ..but I feel - as if I'm on the home run!
0:38:25 > 0:38:30- The magnitude of this event - has certainly struck home.
0:38:30 > 0:38:33- I just want to cry all the time.
0:38:34 > 0:38:37- I know - that it's all down to fatigue.
0:38:39 > 0:38:44- I've probably only had - about 12 hours of sleep...
0:38:44 > 0:38:47- ..in the last six days.
0:38:48 > 0:38:52- On top of that, - I've had to walk many miles.
0:38:53 > 0:38:57- Put me back in the Amazon any day!
0:38:58 > 0:39:00- Having said that...
0:39:00 > 0:39:06- ..being out here has made me realize - how simple life can be.
0:39:07 > 0:39:10- I've got everything I need - either on my back...
0:39:10 > 0:39:13- ..or being dragged behind me.
0:39:14 > 0:39:17- I don't need anything else.
0:39:18 > 0:39:19- Do you know what?
0:39:19 > 0:39:24- I'm happy here. - This is what makes me feel alive.
0:39:25 > 0:39:28- I know that I've been emotional...
0:39:28 > 0:39:31- ..but a lot of that - is down to happiness.
0:39:52 > 0:39:57- As night falls, the wind picks up - and temperatures drop dramatically.
0:39:57 > 0:40:00- In daylight, - it's -15 degrees Celsius...
0:40:01 > 0:40:04- ..but it quickly falls - to -30 degrees Celsius.
0:40:04 > 0:40:08- Lowri is exhausted - and decides to rest for a while...
0:40:08 > 0:40:12- ..after completing 35 miles.
0:40:14 > 0:40:17- I'm so tired.
0:40:18 > 0:40:22- I was staggering all over the road - and I had to stop.
0:40:22 > 0:40:28- Battling against exhaustion - is a waste of time...
0:40:29 > 0:40:33- ..so I'll sleep by the roadside - for a few hours.
0:40:34 > 0:40:39- The walking sticks will remind me - which way to go in the morning.
0:40:39 > 0:40:43- I have heard tales - about past competitors....
0:40:43 > 0:40:48- ..who walked the wrong way - for five hours after bivvying...
0:40:49 > 0:40:53- ..only to meet another competitor - coming towards them.
0:40:54 > 0:40:58- As a result, they lost ten hours - and I don't want that to happen.
0:40:58 > 0:41:03- OK, four hours sleep - on the roadside...
0:41:03 > 0:41:06- ..before I restart this stage.
0:41:07 > 0:41:10- I hope I'll feel better by then.
0:41:20 > 0:41:23- As Lowri - takes a well-deserved rest...
0:41:23 > 0:41:28- ..the Northern Lights - smile down upon her.
0:41:32 > 0:41:38- Four hours later, - and Lowri is back on the Ice Road.
0:41:39 > 0:41:43- Last night, I was so tired...
0:41:43 > 0:41:48- ..I was trying to find a way - to sleep and run at the same time.
0:41:48 > 0:41:53- I tried to close my eyes and run...
0:41:54 > 0:41:56- ..but it wasn't very successful.
0:42:00 > 0:42:04- In every sport, - you need an element of luck.
0:42:04 > 0:42:08- It's been a real blessing that - the strong winds have kept at bay.
0:42:09 > 0:42:11- This race is difficult enough - as it is!
0:42:12 > 0:42:17- Lowri reaches the final checkpoint - before the finishing line.
0:42:17 > 0:42:21- At Swimming Point, she's had enough - of the pain in her feet.
0:42:21 > 0:42:26- She opts for an extreme remedy.
0:42:27 > 0:42:33- I've got a massive blister - all the way around my big toe.
0:42:34 > 0:42:37- She bursts the blister with a pin...
0:42:37 > 0:42:41- ..knowing full well that it will - cause serious problems later...
0:42:42 > 0:42:44- ..as her toe turns septic.
0:42:44 > 0:42:46- Ouch!
0:42:46 > 0:42:48- Oh, that's nice.
0:42:49 > 0:42:51- Relief!
0:42:51 > 0:42:54- She prefers this - to the nagging pain.
0:42:56 > 0:43:00- Before she leaves, an old friend - offers some encouragement.
0:43:00 > 0:43:02- It's Tony Kelly from Abergavenny.
0:43:03 > 0:43:06- It's time for me...
0:43:07 > 0:43:11- ..to dig deep into my soul - and think of home.
0:43:14 > 0:43:17- It's the final 50 miles - of the race...
0:43:18 > 0:43:20- ..and the final 15 hours - of the race...
0:43:21 > 0:43:25- ..and then I'll cross - the finishing line.
0:43:26 > 0:43:30- It's something I've dreamt about - for the last year.
0:43:32 > 0:43:34- It's unbelievable.
0:43:34 > 0:43:36- After a year of training...
0:43:36 > 0:43:42- ..Lowri starts the final stage - from Swimming Point to Tuktoyaktuk.
0:43:43 > 0:43:47- # The day will come when the - meaning of your life becomes clear
0:43:48 > 0:43:51- # We'll extract the juice - from the fruit
0:43:52 > 0:43:56- # We will all be free #
0:43:56 > 0:44:01- This is the final sunset - of my journey.
0:44:02 > 0:44:06- I feel very sad...
0:44:07 > 0:44:12- ..but this is an experience - that I'll never forget.
0:44:13 > 0:44:17- # Simple philosophy
0:44:18 > 0:44:24- # I've got an easy philosophy #
0:44:24 > 0:44:29- I'm coming to the end of my journey. - There's only five miles left.
0:44:29 > 0:44:35- Earlier, I spent about five minutes - alone on the Ice Road.
0:44:35 > 0:44:37- I couldn't hear a thing...
0:44:37 > 0:44:42- ..and was completely in awe - of the scenery surrounding me.
0:44:43 > 0:44:49- Just me and my thoughts - about this personal journey.
0:44:50 > 0:44:53- # To repent
0:44:54 > 0:44:58- # There's no hurry, - I hate breaking into a sweat #
0:44:59 > 0:45:02- It's been a physical...
0:45:03 > 0:45:05- ...emotional and mental battle...
0:45:06 > 0:45:09- ..but it was worth it.
0:45:10 > 0:45:15- # Simple philosophy #
0:45:17 > 0:45:20- I've been at rock bottom...
0:45:20 > 0:45:22- ..but I'm approaching the end now.
0:45:23 > 0:45:26- I can't believe - that this is almost over.
0:45:27 > 0:45:31- I've trained hard for over a year - for this race...
0:45:33 > 0:45:37- ..and I'm already mourning its loss!

0:46:37 > 0:46:43- I want to gather all the emotions - I've experienced this week...
0:46:43 > 0:46:49- ..take the euphoria of this moment - and bottle it to keep forever...
0:46:49 > 0:46:53- ..because this will never happen - to me again.
0:46:53 > 0:46:57- I can't cry any more. - I don't have any tears left.
0:46:58 > 0:47:01- Dreams can come true.

0:47:24 > 0:47:29- I've had endless support - from friends and family back home...

0:47:37 > 0:47:42- I feel as if I've become - a stronger and a better person.
0:47:43 > 0:47:48- This race tore my soul - into tiny pieces...
0:47:48 > 0:47:51- ..but then gradually rebuilt it.
