Athletics stars Mo Farah and Greg Rutherford have shared their tips for young athletes with Newsround.
Greg Rutherford won gold at London 2012 in the long jump.
He told Newsround: "Listen to your own body. Nobody knows you like you, and it's very easy to push yourself too hard."
"If you go to an athletics club, or even if you're doing it at school, try everything," he added.
"Try a bit of throwing, try a bit of jumping... it's a matter of finding what works for you."
