Olympic boxer Amir Khan, heptathlete Denise Lewis and cyclist Chris Hoy head the line-up for the new series of BBC One's Superstars in January.
The classic TV show returns to our screens at the start of the year with a men's, women's and for the first time a Masters competition being contested.
"I'm looking forward to taking part and want to do better than the boxers who appeared last time," said Khan.
"I'm also delighted that so many of my Olympic team mates will be there."
Olympic gold medal winnning cyclists Bradley Wiggins and Chris Hoy, relay runner Marlon Devonish, and rowers Ed Coode and Steve Williams are also taking part.
Other medallists competing include badminton's Nathan Robertson, diver Leon Taylor and swimmer Stephen Parry.
Du'aine Ladejo returns to defend his title, and 2003 competitors Jamie Baulch, Iwan Thomas and Alain Baxter are also taking part.
Denise Lewis is clearly excited about the chance to compete against last time's joint women's winners Zoe Baker and world champion snowboarder Lesley McKenna, as well as the likes of Sonia O'Sullivan, Gail Emms and Georgina Harland.
"Any sporty child of the 80s would have grown up with the show and wondered how they would fare, and now I have that opportunity," she said.
The new Masters competition will include the likes of John Barnes, Jonathan Davies, Ellery Hanley and Barry McGuigan.
Superstars competitors take part in six out of eight events - they are ruled out of one event that is their sport or similar to it, and they choose to sit out another.
Events for the heats are kayak, sprint, shot put, swim, football, cross country, gym tests and mountain bike.
For the final, shot put, football and cross country are replaced by tennis, golf and basketball.
