:00:24. > :00:28.Exactly three days and four hours to the Olympics Opening Ceremony.
:00:28. > :00:34.The countdown is on. I'm Hayley. He's Ricky, and over the next ten
:00:34. > :00:39.minutes Newsround's all about London 2012. Anyone for water polo?
:00:39. > :00:45.The events you might not know much about. And why win one gold when
:00:45. > :00:48.you can win five? We speak to Olympic legend, Sir Steve Redgrave.
:00:48. > :00:55.First though, lots of juicy Olympic nuggets to get through. Athletes
:00:55. > :01:01.from across the world are continuing to arrive in London.
:01:01. > :01:06.With all the equipment he needs. Bikes and canoes are being brought
:01:06. > :01:10.in as excitement builds for Friday. Here's the British swimming team
:01:10. > :01:18.having just flown to London, where Team GB have their official welcome
:01:18. > :01:21.tonight. But will the triple jumper Phillips Idowu, one of Britain's
:01:21. > :01:25.top medal hopes, be joining them? He's pulled out of the training
:01:25. > :01:28.camp in Portugal with a hip injury. Now, Olympic bosses want to see his
:01:28. > :01:31.medical records. The top man at the British Olympic Association says
:01:31. > :01:34.the British team for London 2012 is the best ever. Lord Moynihan said
:01:34. > :01:37.performance is at a level never seen before, and the team is the
:01:37. > :01:40.best prepared in Olympic history. So can they beat the fourth place
:01:40. > :01:44.in the medal table, which is what they got in Beijing? And who's
:01:44. > :01:47.going to get those shiny medals? Everyone knows all about the likes
:01:47. > :01:50.of Chris Hoy, Rebecca Adlington and Tom Daley. But there's an
:01:50. > :01:56.incredible 35 teenagers in Team GB's Olympic squad this summer,
:01:56. > :01:59.each desperate to become a star on the world's biggest stage. It's in
:01:59. > :02:03.the Olympic Stadium, just over there, that some of the Games'
:02:03. > :02:06.biggest fireworks will be set off. The men's 100m final is the
:02:06. > :02:10.showpiece event and Britain has a young star hoping to blast past
:02:10. > :02:15.Bolt. Just eight months ago, Adam Gemili was playing football for
:02:15. > :02:23.non-league side Thurrock. Now, he's the fastest junior sprinter in the
:02:23. > :02:26.world and has Usain in his sights. Next stop the pool. Team GB go into
:02:27. > :02:31.the Games with one of the best-ever British Olympic swimming teams. The
:02:31. > :02:33.women's team is one to watch for medal hopes. Aimme Willmott has a
:02:33. > :02:39.point to prove after missing out on last year's World Championships
:02:39. > :02:42.because the trials clashed with her school exams. She'll have a tough
:02:42. > :02:47.task to medal this summer, but she's got all the skills to pull
:02:47. > :02:51.off a shock. Andy Murray's hopefully wiped those Wimbledon
:02:51. > :02:55.tears away by now. The Scot stands a real chance of gold, especially
:02:55. > :02:59.since Rafael Nadal pulled out through injury. But perhaps it's
:02:59. > :03:04.time to turn Murray Mount in to Robson's Ridge. Laura won her first
:03:04. > :03:07.title when she was just 14 years old. She says she's missed out on a
:03:07. > :03:11.few party's in order to cram in some extra training sessions, so
:03:11. > :03:15.lets hope it pays off. So the stage is set, the athletes are all here
:03:15. > :03:18.and Team GB seem set to take the Games by storm. And with so many
:03:18. > :03:26.young stars in the squad, there should be plenty more medals to
:03:26. > :03:29.come in the future too. So, in just a few days, the eyes of the world
:03:29. > :03:32.will be on the Olympic Park in East London. Billions of pounds have
:03:32. > :03:40.been spent on making it look great. But what was it like before? Leah
:03:40. > :03:46.grew up there and this is her guide to the neighbourhood. Most people's
:03:46. > :03:56.idea of the area where I was brought up was this. Pack your bags,
:03:56. > :03:57.
:03:57. > :04:01.sling your hook and go. But one of the best places to get a real sense
:04:01. > :04:05.of East London is here, Whitechapel market and even though the park is
:04:05. > :04:09.just four miles down the round, it's the East London I've always
:04:09. > :04:13.known. This is a place bursting with a colourful mix of people,
:04:14. > :04:17.food and culture. It's noisy, crowded and sometimes messy, but
:04:17. > :04:22.with influences from all over the world from Bangladesh to Somalia,
:04:22. > :04:25.it's a place like no other. My grandparents settled here in the
:04:25. > :04:29.1950s and whilst it was very different then, it was just as
:04:29. > :04:34.vibrant. They came to work here and settled in the borough of Tower
:04:34. > :04:38.Hamlets. Today, the rez departments are some of the poorest in the --
:04:38. > :04:43.residents are some of the poorest in the city. One of the hopes is
:04:43. > :04:46.that the Games will bring jobs and money, helping to turn around local
:04:46. > :04:50.fortunes and some people are excited at getting the chance to
:04:50. > :04:55.show off their communities, like these school kids who were picked
:04:55. > :04:59.to perform at the closing ceremony. Vs the Games here and getting the
:04:59. > :05:02.teenagers -- having the Games here and getting the teenagers to
:05:02. > :05:06.perform means we are not all stereotypes. No-one gets the
:05:06. > :05:11.opportunity, so it means a lot. biggest sporting event on the
:05:11. > :05:13.planet kicks off in a matter of days right here. For many, it's a
:05:13. > :05:19.life-changing moment. For me, it's a chance to show off my
:05:19. > :05:22.neighbourhood to the rest of the world. Thanks, Leah. Well, we all
:05:22. > :05:25.know abut the running, the swimming and the cycling. But there are some
:05:25. > :05:31.events at London 2012 you probably won't be so familiar with. So bring
:05:31. > :05:34.on the Newsround guide to odd Olympic sports. First up is a
:05:34. > :05:36.seriously sporty mis-match. The modern pentathlon. It involves
:05:36. > :05:40.fencing, swimming and horse riding. Then, three rounds of target
:05:40. > :05:43.shooting and running are chucked in at the end. The event used to be
:05:43. > :05:48.held over four or five days, but now the athletes tackle all that in
:05:48. > :05:52.just one day. Next up, canoe slalom and this is no easy paddle
:05:52. > :05:55.downstream. Competitors have to negotiate a slalom course down
:05:55. > :06:03.white water rapids. An amazing 13,000 litres of water follows down
:06:03. > :06:07.the course every second. And if water sports are your thing, then
:06:07. > :06:10.check out this - water polo - teams race to the middle of the pool for
:06:10. > :06:14.the ball and have only 30 seconds to score. To make it even harder
:06:14. > :06:17.players aren't allowed to touch the bottom - that means they could be
:06:17. > :06:20.swimming for up to three miles every match. But if you're looking
:06:20. > :06:25.for a more unusual Olympic spor,t head back to the history books. Tug
:06:25. > :06:28.of war used to be one of the highlights. At the London Games in
:06:28. > :06:31.1908 it caused a massive row when one team was disqualified for
:06:31. > :06:36.wearing extra heavy steel boots to help them win. Luckily, or sadly,
:06:36. > :06:40.tug of war was ditched as an Olympic sport shortly after that.
:06:40. > :06:43.Let's go back to Leah in East London now. As we heard, billions
:06:43. > :06:47.have been spent on everything from putting in whole new railway lines
:06:47. > :06:56.to building huge stadiums. But what happens to all this stuff, and the
:06:56. > :07:00.people who live there, once it's all over? It's taken seven years
:07:00. > :07:04.for East London to be ready to host the biggest sporting event in the
:07:04. > :07:07.world. It's cost the UK billions of pounds and some of that cash has
:07:07. > :07:11.been spent sprucing up the surrounding neighbourhood and
:07:12. > :07:17.preparing to host the Games. This was the high road in Leighton just
:07:17. > :07:21.around the corner from the Olympics last year. This part of London has
:07:21. > :07:25.had a serious lick of paint, but when everyone leaves, what's next
:07:25. > :07:29.for the area that hosted the world? Wherever in the world the Games
:07:29. > :07:34.arrive, there's always lots of change in store. The people in
:07:34. > :07:38.charge of the 2004 Games in Greece pumped in billions to get things
:07:38. > :07:41.right, but as I saw in November last year, many of the venues lie
:07:41. > :07:48.unused now. Have the organisers of the London Games learnt the lessons
:07:48. > :07:52.of the past? There's a lot of things that are going to happen
:07:52. > :07:56.about the stadium itself. I'm confident that that is going to get
:07:56. > :07:59.a good new owner that will make the best use, and also one that is
:07:59. > :08:04.really committed to community use. Another reason why so much money
:08:04. > :08:09.has been spent bringing the Games here, was to inspire a new
:08:09. > :08:13.generation of sports lovers, but there are no guarantees this will
:08:13. > :08:16.happen. The billions of pounds spent has already changed lives for
:08:16. > :08:20.the good and now everyone will be watching to see what this means for
:08:20. > :08:23.the rest of East London for decades to come. Just time to end the show
:08:23. > :08:33.with a man who's been in five Olympic Games and won a gold medal
:08:33. > :08:34.
:08:34. > :08:39.at every single one. We bring you Sir Steve Redgrave. I'm Sir Steve
:08:39. > :08:46.Redgrave and competed in five different Games from 1984 in LA to
:08:46. > :08:50.2000 in Sydney. It's always very difficult to pick out one moment,
:08:50. > :08:53.but I think the first moment you win your first Olympic gold medal
:08:53. > :08:57.you have a dream to become a champion and that first one is that
:08:57. > :09:03.dream becoming reality. COMMENTATOR: They've crossed the
:09:03. > :09:10.line and there is gold for Great Britain. We were back in the main
:09:10. > :09:13.village at 1pm because we raced so early. And you think, "I'm the
:09:13. > :09:16.champion." It because you have put everything on to that moment in
:09:16. > :09:19.time and not thought about what is happening after, even though you
:09:19. > :09:25.are hugely excited, there is still a real world out there and you are
:09:25. > :09:31.thinking, what will I do next? But, I kept most of the time saying,
:09:31. > :09:37."Let's try to do it again." I did that five times over. How did I do
:09:37. > :09:42.at the Olympics? I didn't do too bad. COMMENTATOR: Five for this man,
:09:42. > :09:48.38 years old. What a British hero. Six medals and five of them gold,
