Make a note of these 10 names. They all have the potential to be on medal podiums for years to come.
Their achievements in 2015 have earned them a place on the shortlist for the BBC Young Sports Personality of the Year.
One of these teenagers will follow in the footsteps of past winners, Claudia Fragapane, Ellie Simmonds, Wayne Rooney, Amber Hill, Tom Daley and Andy Murray.
The top three, chosen by an expert panel, will be named on Blue Peter on Thursday, 10 December (17:00 GMT, CBBC).
The overall winner will then be announced live on Sunday, 20 December, when Belfast hosts Sports Personality of the Year 2015.
