0:00:08 > 0:00:11I kayaked 2,000 miles along the Amazon.
0:00:18 > 0:00:23I walked a high wire between the chimneys at Battersea Power Station.
0:00:25 > 0:00:31And this time around, I'm going to be taking on my most physically demanding challenge to date.
0:00:38 > 0:00:40I'll be attempting to get to the South Pole
0:00:40 > 0:00:44entirely under my own steam, and taking everything I need with me.
0:00:44 > 0:00:47I'll be walking, kite skiing,
0:00:47 > 0:00:52and, in a world first, trying to cycle part of my route to the Pole.
0:00:52 > 0:00:56It's the coldest and windiest place on Earth.
0:00:56 > 0:00:59Temperatures drop to as low as minus 50 degrees Celsius.
0:00:59 > 0:01:03I have no idea how people do this. Honestly!
0:01:03 > 0:01:05CRIES OUT
0:01:11 > 0:01:15I don't want to play any more! This is just so frustrating.
0:01:26 > 0:01:29So far, for her Sport Relief challenge,
0:01:29 > 0:01:32Helen's started to learn the kite skills
0:01:32 > 0:01:36that she hopes will get her 500 miles to the South Pole.
0:01:36 > 0:01:39But a nasty fall has shattered her confidence.
0:01:39 > 0:01:42And she's travelled to Sierra Leone
0:01:42 > 0:01:45to see how Sport Relief money really makes a difference.
0:01:50 > 0:01:57In today's programme, Helen's off to New Zealand to turn kite surfing into kite skiing.
0:01:57 > 0:02:00- Ow!- Her sled gets the better of her.
0:02:02 > 0:02:04I knew that was going to happen!
0:02:04 > 0:02:10And she gets to experience just how extreme conditions could be in Antarctica.
0:02:25 > 0:02:29Kite skiing is the fastest and most dangerous form of transport
0:02:29 > 0:02:33Helen will be using on her 500-mile journey to the South Pole.
0:02:33 > 0:02:36She'll be travelling at speeds of up to 22 miles per hour,
0:02:36 > 0:02:40and, watching these guys, it's clear she's got a lot to learn.
0:02:40 > 0:02:44Those guys make it look easy, but even they've had accidents,
0:02:44 > 0:02:47so, if I'm going to stand any chance of getting to the South Pole in one piece
0:02:47 > 0:02:50I'm going to have to get good at this, and fast.
0:02:50 > 0:02:53Teaching Helen the ropes is Sarah McNair-Landry.
0:02:53 > 0:02:57In 2004, she was the youngest person ever to travel unsupported
0:02:57 > 0:03:02from the coast of Antarctica to the South Pole.
0:03:02 > 0:03:07Sarah covered a staggering 684 miles on skis, aged just 18.
0:03:07 > 0:03:11- You must be Sarah?- Yes, you must be Helen!- Nice to meet you!
0:03:11 > 0:03:14I need to download everything you know about the South Pole.
0:03:14 > 0:03:17How did you get there, and what methods did you use?
0:03:17 > 0:03:21I skied to the South Pole from the coast,
0:03:21 > 0:03:24and, once we got to the South Pole, we picked up kites,
0:03:24 > 0:03:27and then we kited back to the coast.
0:03:27 > 0:03:30Am I right in thinking you did this with your mum and your brother?
0:03:30 > 0:03:35Yes, it's a team of five, and on the team was my older brother and my mother was also on the team.
0:03:35 > 0:03:37I need to learn to kite ski.
0:03:37 > 0:03:40You've done it, how easy is it going to be to learn?
0:03:40 > 0:03:42It's basically two skills in one.
0:03:42 > 0:03:46You need to learn to fly the kite, and you need to learn how to ski.
0:03:46 > 0:03:50Helen's already learnt kite surfing in the UK but it wasn't plain sailing.
0:03:50 > 0:03:54She struggled with setting up the equipment and controlling the kite in strong winds.
0:03:54 > 0:04:00But now she's got to transfer those skills on to the ice and snow, which is a lot more dangerous.
0:04:00 > 0:04:04Sarah's taking her into the mountains for her first lesson.
0:04:04 > 0:04:09- It's got quite windy now, hasn't it? - It has, the winds are picking up.
0:04:09 > 0:04:12They're probably a little over 10 miles an hour now.
0:04:12 > 0:04:16- Could that lift me off the ground?- It could, with a big enough kite.- OK.
0:04:16 > 0:04:22The important things to keep in mind are there's a couple of ways to stop the kite.
0:04:23 > 0:04:26It's vital Helen knows how to kill the power in the kite
0:04:26 > 0:04:29so Sarah gives her a quick safety briefing.
0:04:29 > 0:04:33- If you pull this, you're waving goodbye to your kite.- OK.
0:04:33 > 0:04:37- Which isn't the best thing to do when you're in Antarctica.- No.
0:04:37 > 0:04:40I was quite excited, but given that this thing has three brakes,
0:04:40 > 0:04:45that kind of reminds me that it is quite dangerous.
0:04:45 > 0:04:49But there's no time for nerves, as it's on with the skis.
0:04:51 > 0:04:53OK! You're on your own!
0:04:53 > 0:04:55Hey ha-hey!
0:04:56 > 0:04:58Woohoo!
0:05:09 > 0:05:12It's a positive start for Helen
0:05:12 > 0:05:16and, already, things seem to be coming together.
0:05:18 > 0:05:20But suddenly the wind drops
0:05:20 > 0:05:23and Helen's kite skiing training grinds to a halt.
0:05:23 > 0:05:27In New Zealand, just like Antarctica, Helen's progress is dependent on the weather.
0:05:29 > 0:05:33- You did well.- I was doing OK, wasn't I? I was turning round.- Yes.
0:05:33 > 0:05:39I mean I'm a bit frustrated that I only sort of had probably an hour, less even, wasn't it?
0:05:39 > 0:05:44But I feel good that I've done a bit, and at least I know now, yeah,
0:05:44 > 0:05:46in theory I can do it, I can do the basics.
0:05:46 > 0:05:49It's a bit harder than light ones.
0:05:49 > 0:05:52When it's really, really light, it's impossible to come back up.
0:05:52 > 0:05:56On her 500-mile journey to the South Pole, the type of transport
0:05:56 > 0:05:59Helen uses will be dictated by the weather conditions.
0:05:59 > 0:06:03If there's no wind, she won't be able to kite ski,
0:06:03 > 0:06:06and, if there's too much wind, she won't be able to cycle.
0:06:06 > 0:06:12In that situation, Helen will have to rely on the age-old method of polar travel - cross country skiing.
0:06:14 > 0:06:19In Antarctica, Helen will use cross-country skis to pull her sled,
0:06:19 > 0:06:21which is known as man-hauling.
0:06:21 > 0:06:24It's physically demanding and uses all the muscles in the body.
0:06:24 > 0:06:28Captain Scott used this method on his expedition to the South Pole,
0:06:28 > 0:06:31pushing every man to breaking point.
0:06:31 > 0:06:35To build up her strength for this method of transport,
0:06:35 > 0:06:37Helen's been tyre-pulling in the UK.
0:06:37 > 0:06:41Sarah is putting all that training to the test with a challenge -
0:06:41 > 0:06:46to cross country ski up and down a hill, man-hauling a heavy sled.
0:06:46 > 0:06:51- Is it easy to ski uphill?- Erm... - "Yes," I'm looking for! "Yes!"
0:06:51 > 0:06:53It's a lot of work when you're hauling your sled
0:06:53 > 0:06:57because you're going to be dragging this thing behind you.
0:06:57 > 0:07:00And that "thing" will weigh over 80 kilograms,
0:07:00 > 0:07:02the same as a fully-grown man.
0:07:02 > 0:07:06there's nothing for it but to clip in and take to the hills.
0:07:06 > 0:07:08Are you kidding me?!
0:07:09 > 0:07:13If you start slipping back and you can't pull the sled forward,
0:07:13 > 0:07:17- remember to put your skis in a V so you can get more grip.- OK.
0:07:20 > 0:07:22This is really not easy.
0:07:27 > 0:07:30I've gone about 50 metres!
0:07:30 > 0:07:36I mean it's literally going to take me about two years to get to the South Pole in this way, isn't it?
0:07:41 > 0:07:43I think she's doing OK.
0:07:43 > 0:07:46I think she's realising how hard it's going to be in Antarctica.
0:07:46 > 0:07:49I think it's an eye-opener for her.
0:07:52 > 0:07:54Finally, Helen makes it to the top of the ridge
0:07:54 > 0:07:57but what goes up...
0:07:57 > 0:07:58..must come down!
0:08:02 > 0:08:03Next!
0:08:07 > 0:08:10This sled has a life of its own.
0:08:10 > 0:08:13If it clips the back of my heels, I am in trouble.
0:08:15 > 0:08:17Sled!
0:08:17 > 0:08:19Sled! Oh no!
0:08:22 > 0:08:24I knew that was going to happen!
0:08:24 > 0:08:29I didn't know what to do, I was just like, "Oh no, brace yourself!"
0:08:32 > 0:08:36It didn't hit me. Oh dear. Crikey!
0:08:38 > 0:08:40No, what are you doing?!
0:08:42 > 0:08:46Sledge, you and I are going to fall out.
0:08:49 > 0:08:54I've never felt so stupid in all my born days because, trust me,
0:08:54 > 0:08:57it's easy to watch and say, "Don't do it like that!"
0:08:57 > 0:09:00I know what I should and shouldn't be doing, but doing it
0:09:00 > 0:09:05with a huge big weight attached to the back of me makes it a little bit more complicated.
0:09:05 > 0:09:08Enough is enough. The skis are coming off.
0:09:08 > 0:09:12I kind of feel like I'm copping out,
0:09:12 > 0:09:15but then, on the other hand, actually, this is more sensible.
0:09:15 > 0:09:19I can get down in one piece or I can risk breaking my legs.
0:09:22 > 0:09:26Antarctica is about finding the easiest and most efficient way to get there,
0:09:26 > 0:09:29so if it's taking your skis off and walking down the hill,
0:09:29 > 0:09:34- if that's the easiest, then that's the best thing to do.- I got here!
0:09:34 > 0:09:37I have to tell you, I did not enjoy that!
0:09:37 > 0:09:38Oh!
0:09:41 > 0:09:43It was a good day, we had fun.
0:09:43 > 0:09:46It's also really important that Helen gets these skills down
0:09:46 > 0:09:49because, when there's no wind, this is what she'll be doing in Antarctica,
0:09:49 > 0:09:53hauling all her gear and sled, so this is the place to learn,
0:09:53 > 0:09:57when it's still nice and warm outside and we have time to stop and I can teach her.
0:09:57 > 0:09:59When she gets down to Antarctica,
0:09:59 > 0:10:02she'll have to know these skills already.
0:10:02 > 0:10:05Sarah may be feeling positive at the end of day one
0:10:05 > 0:10:08but, for Helen, there's been more downs than ups.
0:10:08 > 0:10:14I feel really stupid because I totally underestimated
0:10:14 > 0:10:19how hard it is to pull a sled full of stuff up the hill on skis.
0:10:19 > 0:10:21I thought this would be the easy bit!
0:10:21 > 0:10:24I know I'm at the start of this journey and I've got a lot to learn,
0:10:24 > 0:10:27and I know I've got a lot of training and practising to do,
0:10:27 > 0:10:32but I feel like I am a million miles away from the South Pole.
0:10:32 > 0:10:38Not in terms of distance, but in terms of mentally and physically where I need to be.
0:10:52 > 0:10:56It's day two of Helen's New Zealand training and the wind has really picked up -
0:10:56 > 0:11:00perfect for her second kite skiing lesson.
0:11:00 > 0:11:04It's time to bring out the big kite.
0:11:04 > 0:11:06Yesterday it was light winds
0:11:06 > 0:11:09and you were doing big movements with the kite.
0:11:09 > 0:11:11Right now it's stronger winds,
0:11:11 > 0:11:14so, the faster you move this kite, the more it's going to pull you.
0:11:14 > 0:11:17You have the brake, your safety releases,
0:11:17 > 0:11:22and if it's too windy you also have a smaller kite that you can put up.
0:11:23 > 0:11:26As soon as the kite takes off, Helen's overwhelmed by the power.
0:11:26 > 0:11:28Ow!
0:11:30 > 0:11:34See, I panicked there, and I just pulled the release. Because I knew...
0:11:34 > 0:11:35Oh!
0:11:35 > 0:11:39See, the trouble is, once you've been hurt with these, you get nervous, don't you?
0:11:39 > 0:11:41Yep.
0:11:41 > 0:11:44Back in the UK, Helen was pulled over while learning to kite surf
0:11:44 > 0:11:46and sustained a painful foot injury.
0:11:46 > 0:11:52- Oh my word!- It's playing on her mind and affecting her confidence.
0:11:52 > 0:11:56To get her back on track, Sarah wants Helen to try a different kite.
0:11:56 > 0:11:59It's a bit smaller, it'll be much easier for her to handle,
0:11:59 > 0:12:03so it'll be great for her to get her confidence back up, get skiing.
0:12:22 > 0:12:25The smaller kite is really doing the trick.
0:12:25 > 0:12:28Helen's making progress fast and building her confidence.
0:12:33 > 0:12:38I am absolutely loving it! I'm just going to land this kite.
0:12:38 > 0:12:40I'm loving it now.
0:12:40 > 0:12:44It's so weird how just the change of a kite size makes the world of difference.
0:12:44 > 0:12:48I love it, and I want to go fast and I want to go downhill.
0:12:48 > 0:12:49We could bring a kite.
0:12:49 > 0:12:53Every time it picked up wind and speed, I was like, "No, I'm not liking this!"
0:12:53 > 0:12:57Now that Helen's getting up to speed with kite skiing,
0:12:57 > 0:13:01Sarah brings back an old friend to end the day with.
0:13:01 > 0:13:04Oh good, the sled's here(!)
0:13:04 > 0:13:06Oh, that thing!
0:13:06 > 0:13:10I know I need to learn it, but this is the worst bit, isn't it?
0:13:10 > 0:13:15Getting used to it and avoiding it and trying to not get hurt.
0:13:15 > 0:13:16It's going to be the hardest bit.
0:13:16 > 0:13:20Sarah clips on the sled and off she goes.
0:13:23 > 0:13:28I've had two days on the skis, and I was pulling the sled.
0:13:28 > 0:13:31I was going uphill, I went upwind,
0:13:31 > 0:13:35so I just need to remind myself that actually I am doing it.
0:13:35 > 0:13:41I don't know why I'm giving myself a hard time, saying it's scary and I can't do it because I am doing it,
0:13:41 > 0:13:43and I'm going to have to keep my nerve in Antarctica.
0:13:43 > 0:13:47Otherwise I'm going to go a few metres and then go "Oh no, I'm just going to put it down!"
0:13:47 > 0:13:50It's going to take me ages to get to the South Pole.
0:13:50 > 0:13:56If I can master this, I'm going to make this journey a whole lot easier.
0:13:59 > 0:14:03It's not just physical skills Helen needs to learn in New Zealand.
0:14:03 > 0:14:07Eating the right food is crucial for big expeditions
0:14:07 > 0:14:10so Sarah's sending Helen to a local supermarket
0:14:10 > 0:14:14to pick up enough food for one day in Antarctica.
0:14:15 > 0:14:21In Antarctica, Helen will need extra energy to keep warm in temperatures of minus 50,
0:14:21 > 0:14:25and to cope with all the physical activity she'll be doing.
0:14:25 > 0:14:28A grown woman needs around 2,000 calories a day.
0:14:28 > 0:14:34On her journey to the South Pole, Helen will be eating up to 6,000 calories a day,
0:14:34 > 0:14:36that's three times her normal amount.
0:14:36 > 0:14:40If she doesn't, it could have life-threatening consequences.
0:14:46 > 0:14:49And so I need things that are light and easy to carry.
0:14:49 > 0:14:52I don't want things I'm going to have to cook or prepare,
0:14:52 > 0:14:55and I need things that have got a lot of calories
0:14:55 > 0:14:58because I'm going to be burning a lot of calories.
0:15:02 > 0:15:04# Doo doo da da! #
0:15:04 > 0:15:08I'm going to have some liquorice allsorts, just because I like them!
0:15:14 > 0:15:20Fruit would be nice, but it'll just get bruised in the bag.
0:15:22 > 0:15:25I am going to want some sort of hot food,
0:15:25 > 0:15:31and I think pasta in a bag is a good idea because I can melt snow and boil it.
0:15:32 > 0:15:35Meat and cheese is good, isn't it?
0:15:35 > 0:15:40I have to look at food as fuel and I need the calories and sugar
0:15:40 > 0:15:43to keep going because it's going to be long days.
0:15:46 > 0:15:49It's not going to happen, is it?
0:15:49 > 0:15:53All I need now is something to drink.
0:15:53 > 0:15:55I'm going to take two.
0:16:00 > 0:16:03Done. I think that will definitely see us through a day in Antarctica.
0:16:03 > 0:16:05Shh!
0:16:06 > 0:16:09Lets just hope Sarah agrees.
0:16:11 > 0:16:13I don't want to be too confident,
0:16:13 > 0:16:17but I'm feeling quite proud of my shopping.
0:16:17 > 0:16:19Let's see what you've got.
0:16:22 > 0:16:24- OK, so we've got breakfast.- Yes.
0:16:24 > 0:16:28- This is during the day?- Yes. - So what's your dinner?
0:16:28 > 0:16:31Some more of this, or maybe another one of these.
0:16:31 > 0:16:34Starting with breakfast, it's definitely not enough calories.
0:16:34 > 0:16:39But in the morning we haven't burnt anything off so why is it important to add more at that stage?
0:16:39 > 0:16:40Because it's the first meal of your day
0:16:40 > 0:16:44and you're trying to start with a lot of energy to last you throughout the day.
0:16:44 > 0:16:49So lunch, first thing is how would you cook these when you're outside?
0:16:49 > 0:16:54- Burning water. But we won't be doing that at lunchtime, will we?- Exactly.
0:16:54 > 0:16:58- So, for lunch, you want a lot of little snacks instead of one big meal.- OK.
0:16:58 > 0:17:00So, dinner...
0:17:00 > 0:17:04- The idea is really good, but just ones with more calories.- OK.
0:17:04 > 0:17:10- So I'm going to calculate out how many calories in total to see if it's enough for a day.- OK.
0:17:10 > 0:17:12Oh! I thought I was doing so well!
0:17:12 > 0:17:17Helen's really underestimated just how much she needs to eat,
0:17:17 > 0:17:21but by how much? Sarah adds up the amount of calories.
0:17:21 > 0:17:28- The final count for this food is 5,000 calories.- Mm-hmm.
0:17:29 > 0:17:35However, for one person, one day, you need to be consuming 6,000 calories.
0:17:35 > 0:17:40- So, for me alone, I'd have to eat all of this and more?- Yep.
0:17:40 > 0:17:44And quite a bit more. Another couple of these!
0:17:46 > 0:17:48# Food glorious food... #
0:17:48 > 0:17:51To get Helen fit for her South Pole trip,
0:17:51 > 0:17:55Sarah is cooking up a meal which contains 2,000 calories -
0:17:55 > 0:17:58the amount she needs for one meal in the Antarctic.
0:17:58 > 0:18:03- Don't forget the chicken. - And it's a huge amount of food!
0:18:03 > 0:18:04Would you like some cake too?
0:18:04 > 0:18:08- To Antarctica!- Cheers!
0:18:08 > 0:18:11# Just eat it! Eat it!
0:18:11 > 0:18:14# Get yourself an egg and beat it!
0:18:14 > 0:18:17# Have some more chicken, have some more pie
0:18:17 > 0:18:21# It doesn't matter if it's boiled or fried,
0:18:21 > 0:18:22# Just eat it
0:18:22 > 0:18:24# Just eat it... #
0:18:24 > 0:18:28Helen can only manage half of what's on her plate,
0:18:28 > 0:18:31but Sarah has some good news in store for her.
0:18:31 > 0:18:36These are all high calories, but also lightweight meals.
0:18:36 > 0:18:40- You add water to them. - Porridge, I like.
0:18:40 > 0:18:44Bulk it up with a little butter to add some fat for breakfast and dinner.
0:18:44 > 0:18:47And in the middle of the day it's just snacky type stuff,
0:18:47 > 0:18:51but enough calories to equate to a meal?
0:18:51 > 0:18:53- Exactly.- OK, well that's good.
0:18:53 > 0:18:57That makes me feel better because it's the volume of all that food that puts me off,
0:18:57 > 0:18:59but porridge for breakfast, if I add water to that.
0:18:59 > 0:19:02So these are condensed high calorie meals
0:19:02 > 0:19:06because you're going for lots of calories and lightweight.
0:19:06 > 0:19:10That is light. Good! That makes me feel a lot better.
0:19:15 > 0:19:19It's time for Helen's final training exercise.
0:19:19 > 0:19:23She'll be spending the night outside in the cold.
0:19:23 > 0:19:26So Sarah shows her how to build a snow hole.
0:19:26 > 0:19:31Snow is a good insulator, keeping heat in as well as providing protection from the wind.
0:19:34 > 0:19:36That is COSY!
0:19:40 > 0:19:44Antarctica is the coldest, windiest, driest continent on Earth.
0:19:45 > 0:19:49It's a land of unpredictable weather.
0:19:49 > 0:19:51Storms and blizzards can come out of nowhere,
0:19:51 > 0:19:56sending the temperature plummeting and bringing on powerful winds.
0:19:56 > 0:20:00Helen will need to be ready for anything to avoid being taken by surprise.
0:20:05 > 0:20:08It's already late afternoon as they set off to a remote spot.
0:20:08 > 0:20:13Sarah tells Helen where she needs to get to by tomorrow morning.
0:20:13 > 0:20:16So I've brought you out here for your last challenge.
0:20:16 > 0:20:20- The goal is to get to the road, which is five miles away.- OK.
0:20:20 > 0:20:24- Here's your GPS.- Got it. - And the end point is in there.
0:20:24 > 0:20:27You can travel whatever method makes the most sense.
0:20:27 > 0:20:32You have food, you have water, you have everything you need. Good luck.
0:20:32 > 0:20:35I'll be fine...hopefully!
0:20:35 > 0:20:40Sarah leaves Helen at the start point. She's now on her own for as long as it takes her to get back.
0:20:40 > 0:20:42I'm quite excited by this
0:20:42 > 0:20:45because I just want to prove to Sarah that I can do it.
0:20:45 > 0:20:50I feel like this is my chance to get stuck in and get on with it.
0:20:50 > 0:20:55This challenge will simulate exactly what Helen will be doing in the Antarctic.
0:20:55 > 0:20:57She'll have to make all the decisions,
0:20:57 > 0:21:02especially when it comes to the right method of transport for the weather conditions.
0:21:02 > 0:21:06At the moment there's good wind, so Helen decides to kite ski
0:21:06 > 0:21:10in the hope of covering some ground before nightfall.
0:21:15 > 0:21:18But, just as Helen gets started, the wind drops
0:21:18 > 0:21:22and there's nothing for it but to go back to basics.
0:21:22 > 0:21:24I'm getting nowhere with the kite.
0:21:24 > 0:21:29It's going to be quicker to walk up the hill.
0:21:29 > 0:21:32And light is fading fast.
0:21:42 > 0:21:44I'm nowhere near the road.
0:21:44 > 0:21:48I've probably only covered about half a mile but I'm not downbeat
0:21:48 > 0:21:50because I was actually kite skiing
0:21:50 > 0:21:54and pulling that sled up a hill so I'm happy about that.
0:21:54 > 0:21:57It does mean I'm going to have to sleep outside,
0:21:57 > 0:22:01which was kind of on the cards so I've mentally prepared myself for that,
0:22:01 > 0:22:04and I've got a sleeping bag and stuff in here.
0:22:05 > 0:22:10But before Helen can get into that sleeping bag she has to build her snow hole,
0:22:10 > 0:22:14which involves digging, digging, and more digging!
0:22:18 > 0:22:19SHE LAUGHS
0:22:21 > 0:22:24The wind is definitely picking up.
0:22:24 > 0:22:26Which means she needs to get a move on
0:22:26 > 0:22:30or face the prospect of being stuck in a storm with no shelter.
0:22:38 > 0:22:40Look, I'm in.
0:22:40 > 0:22:44My legs are out, stretched out, but I'm not going to lie...
0:22:44 > 0:22:50I don't like it! Because I want to be able to see the sky.
0:22:50 > 0:22:57So I'd rather sleep like that, which I probably will.
0:22:57 > 0:22:59There, that's cosy.
0:23:00 > 0:23:03After all that physical exercise, it's dinner time.
0:23:03 > 0:23:10And on tonight's menu, a proper expedition meal. Freeze dried beef stroganoff in a bag. Yum.
0:23:10 > 0:23:15If I had a tent, I'd sit inside the tent and eat this. But I don't.
0:23:18 > 0:23:20Mmm!
0:23:23 > 0:23:25Actually, that's not too bad.
0:23:26 > 0:23:31After dinner, it's time to settle down for the night.
0:23:31 > 0:23:34It's quiet. I can see the moon.
0:23:35 > 0:23:40This is... I don't know, I feel lucky all of a sudden.
0:23:40 > 0:23:42I met loads of boys last year who sleep outside
0:23:42 > 0:23:46in Uganda on the street by the side of a dual carriageway
0:23:46 > 0:23:49among a load of rubbish,
0:23:49 > 0:23:54and they are threatened and intimidated by some really nasty people every day.
0:23:57 > 0:24:00This is a total world away from that.
0:24:00 > 0:24:04People would pay a fortune to experience this kind of environment.
0:24:04 > 0:24:07So, yeah, I'm outside, but I just don't think I can complain.
0:24:22 > 0:24:25Good morning!
0:24:25 > 0:24:30Oh, I've got that thing. You know when you first wake up and you need to stretch, but you can't!
0:24:30 > 0:24:33It's not the most comfortable night's sleep I've had
0:24:33 > 0:24:36but it's far from the worst.
0:24:42 > 0:24:47Snow has fallen overnight and Helen's woken up to a total blizzard.
0:24:47 > 0:24:50There's snow in every direction.
0:24:50 > 0:24:54Sarah said use any means possible to get back to the road
0:24:54 > 0:24:56and, with the weather conditions the way they are,
0:24:56 > 0:25:00Helen chooses to walk, but she's not happy about it.
0:25:01 > 0:25:02This is so annoying.
0:25:02 > 0:25:05I've come half the way around the world to learn to kite ski,
0:25:05 > 0:25:12which I need to do, the skill I need, and the weather has just never played ball.
0:25:12 > 0:25:17It's been too windy, not windy enough, and now it's snowing.
0:25:17 > 0:25:21Honestly, I am boiling inside.
0:25:25 > 0:25:29Putting one foot in front of the other is getting Helen where she needs to go,
0:25:29 > 0:25:33not to mention discovering a new form of polar transport!
0:25:33 > 0:25:35Woo-hoo!
0:25:35 > 0:25:38I wonder if anybody has done this to the South Pole!
0:25:41 > 0:25:45It's not quite the blaze of glory that I wanted to cross the finishing line in,
0:25:45 > 0:25:50but Sarah said get back by any means possible.
0:25:50 > 0:25:52And I'm nearly there.
0:25:53 > 0:25:56Helen did well for the conditions,
0:25:56 > 0:26:01and she just kind of used her best judgement to figure out what the best way to travel was.
0:26:01 > 0:26:04I mean, the ultimate goal is for her to get to the South Pole.
0:26:04 > 0:26:07I'm delighted that I made it through that experience.
0:26:07 > 0:26:1224 hours out there in the snow, making my own way back,
0:26:12 > 0:26:13and I'm really chuffed!
0:26:13 > 0:26:16Her strongest point is she has a really great attitude.
0:26:16 > 0:26:21She's really excited about going, she wants to have fun, she's very, very motivated to train,
0:26:21 > 0:26:26and that's one of the keys of any expedition, just to have that good attitude.
0:26:26 > 0:26:30Antarctica may throw, you know, more than I can deal with,
0:26:30 > 0:26:33and I still don't know whether I will be able to cope at this stage.
0:26:33 > 0:26:36I know I've got some skills that might stand me in a better stead,
0:26:36 > 0:26:40but I'm a long way from the finishing line yet.
0:26:40 > 0:26:43And if you've been inspired by Helen's challenge,
0:26:43 > 0:26:47why don't you go the extra mile and get involved in Sport Relief this year?
0:26:47 > 0:26:50Get a grown-up and sign up to do the Sport Relief mile.
0:26:50 > 0:26:53There are hundreds of events around the country.
0:26:53 > 0:26:54By raising money, you can help
0:26:54 > 0:26:57poor and vulnerable people in the UK and around the world.
0:26:58 > 0:27:04Next time: Helen travels to Iceland to learn how to survive in the extreme cold.
0:27:04 > 0:27:09You couldn't put a tent up in this on your own. Or I certainly couldn't.
0:27:09 > 0:27:13She meets her Norwegian team-mate who will travel with her to the South Pole.
0:27:15 > 0:27:18- You must be Niklas. Nice to meet you.- Nice to meet you.
0:27:20 > 0:27:23And bad weather gives her a taste of what's to come.
0:27:23 > 0:27:29I can honestly say this is the most unpleasant experience of my life.
