Every top athlete has to start somewhere.
That's why BBC Sport has teamed up with CBBC, launching a brand-new Blue Peter sport badge in a bid to inspire young people to get active and get into sport.
If you are aged between six and 14 this summer, you can get your hands on one of these special, limited-edition badges. All you have to do is pass on your passion for sport by getting someone you know to do something sporty.
Whether it is taking a friend down to your local football club or encouraging a family member to join a dance session, as long as you follow the instructions and fill out an application form on the Blue Peter website, one of these badges could be yours.
Olympic medallists Tom Daley, Victoria Pendleton and Nicola Adams are among the sports stars to have shared their inspirations with Blue Peter.
Daley, who won bronze at London 2012, said he got into diving by chance.
"I started swimming at three and loved being in the water," said Daley.
"I went to a local swimming session with my family and saw people diving, and just thought I would give it a go. From there I have enjoyed it ever since."
Helen Glover, who alongside Heather Stanning picked up Team GB's first gold medal of London 2012, only took up the sport four years before her incredible achievement at Eton Dorney.
Glover explained: "After watching the Beijing Olympics, it made me think, I can do this and I can win a gold medal in this sport."
Double Olympic gold medallist Rebecca Adlington said it was healthy family rivalry that got her to where she is today: "My two big sisters inspired me and, being the baby of the family, I just wanted to keep up with them and rival them, which luckily I did."
As this is a limited edition badge, application forms must be submitted by 1400 BST on 30 September 2013.
