Usain Bolt, running away from everyone, running towards what he

would like to think his immortality as an athlete.

There's just no stopping him - Usain Bolt wins his second gold

While there was triple gold for Team GB on day 13 of the Games.

Good morning, I'm Jenny and this is your Olympic Newsround.

Team GB have won three more gold medals on day 13

But all eyes on were the superstar of the Games

After winning gold in the 100 metres,

to strike again, this time in the 200 metres.

19.7 nine. It's his eighth goal. Something that you work so hard for

throughout the years. When this moment comes, you are happy but also

relieved to have done it because you really wanted it. So many things

could have gone wrong but I came here and executed. Everything worked

out. It's a brilliant feeling. But it was heartbreak

for Team GB's Adam Gemili, who was just three thousandths

of a second off the bronze medal. Now to winning with your feet

in a different way. Reigning taekwondo champ

Jade Jones defended her title I still can't believe it, you know,

from London, that I'm Olympic champion and to do it again. I just

feel like I was under so much pressure and to do it again is

surreal. Earlier on, another

champ from London 2012 was out to win again -

triathlete Alistair Brownlee, who was competing alongside

his brother Jonny. The pair swam, cycled and ran

their way to gold and silver. It will be a glorious golden 44

Alastair Brownlee. The Olympic triathlon champion for the second

time. Our training has been so hard. I've finished so many sessions just

trying to keep up with Johnny, basically I've raced three or four

times a week and I've hardly been able to sleep at night because my

legs hurt so much. The day's other British gold came

from sailors Hannah Mills and Saskia Clark in

the women's 470 event. Also on the water,

Jon Schofield and Liam Heath powered to a silver

in the men's kayak double. There was a bronze in

another doubles event - the men's badminton,

from Chris Langridge So, all that means we stay in second

place on the medal table. Team GB has dominated the track

cycling at the Games - and today, the finals of the BMX

cycling takes place. But there's been bad news

for Team GB medal hopeful Liam Phillips, who is out

after having a crash Thankfully, he was OK

to walk away afterwards, and later tweeted this selfie of him

in hospital to say he was alright. BMX is a relatively new Olympic

sport - first appearing So we sent Ayshah to a BMX

track to find out more. BMXing is a sport where you jump

over stuff and hope that And the riders at the Olympics

will have to get around They will be jumping over huge bumps

and riding at speeds of over 30 The whole race takes

just 30 to 40 seconds. These guys aren't Olympics ready yet

but they are starting out learning I love the BMXing best because it's

flicks and racing. You have to jump and go really fast

but it hurts when you fall. The coolest thing is

when you go down ramps. I love how you can

jump over the bumps. I just think it's cool

because you can go Well, I can't be here without having

a go myself. I won't be a BMX

champion any time soon. But I can't wait to watch the pros

doing their thing in Rio. That's all from me, Newsround's back

right here at 8.15 with news about one of the country's

most endangered animals.
