:00:15. > :00:17.would like to think his immortality as an athlete.
:00:18. > :00:20.There's just no stopping him - Usain Bolt wins his second gold
:00:21. > :00:24.While there was triple gold for Team GB on day 13 of the Games.
:00:25. > :00:33.Good morning, I'm Jenny and this is your Olympic Newsround.
:00:34. > :00:38.Team GB have won three more gold medals on day 13
:00:39. > :00:42.But all eyes on were the superstar of the Games
:00:43. > :00:49.After winning gold in the 100 metres,
:00:50. > :00:53.to strike again, this time in the 200 metres.
:00:54. > :01:09.19.7 nine. It's his eighth goal. Something that you work so hard for
:01:10. > :01:13.throughout the years. When this moment comes, you are happy but also
:01:14. > :01:18.relieved to have done it because you really wanted it. So many things
:01:19. > :01:19.could have gone wrong but I came here and executed. Everything worked
:01:20. > :01:22.out. It's a brilliant feeling. But it was heartbreak
:01:23. > :01:24.for Team GB's Adam Gemili, who was just three thousandths
:01:25. > :01:28.of a second off the bronze medal. Now to winning with your feet
:01:29. > :01:30.in a different way. Reigning taekwondo champ
:01:31. > :01:42.Jade Jones defended her title I still can't believe it, you know,
:01:43. > :01:47.from London, that I'm Olympic champion and to do it again. I just
:01:48. > :01:48.feel like I was under so much pressure and to do it again is
:01:49. > :01:50.surreal. Earlier on, another
:01:51. > :01:51.champ from London 2012 was out to win again -
:01:52. > :01:54.triathlete Alistair Brownlee, who was competing alongside
:01:55. > :01:56.his brother Jonny. The pair swam, cycled and ran
:01:57. > :02:11.their way to gold and silver. It will be a glorious golden 44
:02:12. > :02:17.Alastair Brownlee. The Olympic triathlon champion for the second
:02:18. > :02:21.time. Our training has been so hard. I've finished so many sessions just
:02:22. > :02:26.trying to keep up with Johnny, basically I've raced three or four
:02:27. > :02:27.times a week and I've hardly been able to sleep at night because my
:02:28. > :02:29.legs hurt so much. The day's other British gold came
:02:30. > :02:31.from sailors Hannah Mills and Saskia Clark in
:02:32. > :02:33.the women's 470 event. Also on the water,
:02:34. > :02:35.Jon Schofield and Liam Heath powered to a silver
:02:36. > :02:37.in the men's kayak double. There was a bronze in
:02:38. > :02:41.another doubles event - the men's badminton,
:02:42. > :02:43.from Chris Langridge So, all that means we stay in second
:02:44. > :03:02.place on the medal table. Team GB has dominated the track
:03:03. > :03:05.cycling at the Games - and today, the finals of the BMX
:03:06. > :03:07.cycling takes place. But there's been bad news
:03:08. > :03:10.for Team GB medal hopeful Liam Phillips, who is out
:03:11. > :03:12.after having a crash Thankfully, he was OK
:03:13. > :03:18.to walk away afterwards, and later tweeted this selfie of him
:03:19. > :03:22.in hospital to say he was alright. BMX is a relatively new Olympic
:03:23. > :03:25.sport - first appearing So we sent Ayshah to a BMX
:03:26. > :03:38.track to find out more. BMXing is a sport where you jump
:03:39. > :03:41.over stuff and hope that And the riders at the Olympics
:03:42. > :03:45.will have to get around They will be jumping over huge bumps
:03:46. > :03:49.and riding at speeds of over 30 The whole race takes
:03:50. > :03:55.just 30 to 40 seconds. These guys aren't Olympics ready yet
:03:56. > :03:58.but they are starting out learning I love the BMXing best because it's
:03:59. > :04:06.flicks and racing. You have to jump and go really fast
:04:07. > :04:10.but it hurts when you fall. The coolest thing is
:04:11. > :04:12.when you go down ramps. I love how you can
:04:13. > :04:20.jump over the bumps. I just think it's cool
:04:21. > :04:25.because you can go Well, I can't be here without having
:04:26. > :04:41.a go myself. I won't be a BMX
:04:42. > :04:43.champion any time soon. But I can't wait to watch the pros
:04:44. > :04:50.doing their thing in Rio. That's all from me, Newsround's back
:04:51. > :04:53.right here at 8.15 with news about one of the country's
:04:54. > :04:56.most endangered animals.
