As well as the main event, Xtreme will also be holding a Plank Challenge, a Push-Up Challenge, a raffle and the Xtreme Bake Off.

James Evans, trainer at Xtreme, said: “We’re really excited for the 24 hour challenge and can’t wait to get stuck in raising money for Sport Relief.

“We want as many people as possible to come down to Waterside and help us with the challenge – whether they jump on the treadmill for 30 minutes, enter the raffle or help us put the calories we’ve burnt off back on by bringing a cake along for the Bake Off, it all helps.

“There really is no excuse for not getting involved, there is something here for everyone to have fun and raise money for Sport Relief.”
