:00:17. > :00:24.on CBBC, and this is on the way. Mo Farah challenges Usain Bolt to a
:00:24. > :00:29.race. And Doctor Who's TARDIS in a living room! This is Newsround.
:00:29. > :00:33.OK, first, we are talking about you. We have done a huge survey about
:00:33. > :00:38.your lives and ask you a lot of questions from, who are your heroes
:00:38. > :00:44.to, what job do you want to do when you are older? We spoke to a group
:00:44. > :00:48.of researchers, and they spoke to over 1600 of the children out there
:00:48. > :00:52.all over the UK aged between eight and 12 years old. Some of the
:00:52. > :00:55.children got back to us with the results, and first we want to know
:00:55. > :01:02.what you want to do when you are older?
:01:02. > :01:09.The world of work is a few years off yet, but what do you want to do?
:01:09. > :01:14.Head of a business in the City? Or a career on the football pitch? When
:01:14. > :01:19.it comes to the boys, 24% of those who took part say they want to be a
:01:19. > :01:24.footballer. 6% want to join the police force, only 4% want to be a
:01:24. > :01:30.games designer. And the girls? Most said they wanted to be a teacher,
:01:30. > :01:40.followed by a hairdresser. Only 8% said they wanted to be an actor.
:01:40. > :01:43.Just 7% wanted to be a singer. And we also ask the children, who
:01:43. > :01:50.are your heroes? 41% of children said it was a member of their
:01:50. > :01:53.family. Top of the list was mum and dad. They also said, 13%, said One
:01:53. > :01:59.Direction where their heroes! We also gave them a list of famous
:01:59. > :02:05.people, we asked who they would like to be like? Boys said they wanted to
:02:05. > :02:08.be like David Beckham, girls said they wanted to be like Rhianna.
:02:08. > :02:15.Loads more information on the survey, guys, over on the website,
:02:15. > :02:19.take a look. Next up, we are talking about wet weather for a change! From
:02:19. > :02:24.a heatwave to flood warnings, heavy rain has fallen across parts of the
:02:24. > :02:28.UK, causing problems in areas like Newcastle, Leicestershire, and a
:02:28. > :02:31.mother and her kids had to be rescued from a river in North
:02:31. > :02:36.Yorkshire yesterday. Experts say the extreme weather we have had so far
:02:36. > :02:40.this year has caused a record number of landslides. The rest of the week
:02:40. > :02:44.will see spells of thundery weather with warm sunshine in between. The
:02:44. > :02:49.Met Office says the hot weather could return in August, but it will
:02:49. > :02:53.be unsettled. Typical school holiday weather!
:02:53. > :02:57.One is the world's fastest man, the other is a double Olympic champion,
:02:57. > :03:02.but what would happen if Usain Bolt took on Mo Farah in a race over 600
:03:02. > :03:06.metres? It is a challenge both athletes are up for, and now has
:03:06. > :03:11.been finding out who would come out on top.
:03:11. > :03:15.They were two of London 2012's biggest stars, masters of the track
:03:15. > :03:20.and the best in the world at what they do. Coming second is not
:03:20. > :03:26.something Mo Farah or Usain Bolt are used to hearing, but after the
:03:26. > :03:34.lightning Bolt accepted a challenge from Mo, that is about to change.
:03:34. > :03:39.The Jamaican sprinter has six gold medals, specialising in sprints. Mo
:03:39. > :03:44.is a long distance specialist, winning gold in the 5000 metres and
:03:44. > :03:49.10,000 metres last summer. Mo has proposed a distance of 600 metres,
:03:49. > :03:54.but whose style would be better suited? Every day of the week Mo
:03:54. > :03:59.Farah would win that, because it is, essentially, an aerobic event.
:03:59. > :04:04.He has got to get rid of the lactic acid that will build up, he will do
:04:04. > :04:08.that better than Usain Bolt. Top speed will not be important. For 400
:04:08. > :04:13.metres, Bolt will be 20 metres in front. By 600 metres, he will be
:04:13. > :04:20.gasping, on his knees. So is that if the science, but who do you think
:04:20. > :04:25.will win? Mo Farah, because Usain Bolt will not have the stamina.
:04:25. > :04:30.think Usain Bolt, he was really good, really fast. It depends on
:04:30. > :04:34.what type of race, but Mo Farah is very good at long distance. A date
:04:34. > :04:40.for the race has yet to be set, but if and when it goes ahead, tickets
:04:40. > :04:44.would be likely to sell-out even faster than either of them run.
:04:44. > :04:48.Now, if there is a sporting showdown you want to see, head over to the
:04:48. > :04:55.website and let us know. Next, do you know the name for a Doctor Who
