Entertainer Timmy Mallett pulled on his gym kit on Friday as he took on the Cracker 10:10 Challenge.
The Magnet Leisure Centre has been inviting fitness fans to take part in the rigorous gym session since September.
It includes spending 10 minutes running and 10 minutes cycling, with prizes awarded to those who can travel the furthest distance.
Timmy said he had really enjoyed taking part in the challenge and helping to raise some valuable cash.
"The Cracker Appeal is a great cause," he added.
"It is always nice to do something for someone else, it is a really powerful thing to do."
Former X Factor contestant and girlband member Daizy Dance will be getting sweaty in support of the appeal on Friday.
