OLYMPIC champion Greg Rutherford striped down to just his pants and gold medal for a group of lucky competition winners to draw.
Almost 1,000 people bid for a place in the exclusive class arranged by Groupon to raise awareness of testicular cancer for the Male Cancer Awareness Campaign.
Among the select few was Michaela Firth from Milton Keynes, who posed with the long-jump gold medallist for pictures and even got him to sign her attempt.
The Male Cancer Awareness Campaign is a charity close to Greg’s heart, after one of his friends was diagnosed with the disease.
Greg said: “I’ve got a mate who’s been suffering with testicular cancer and he’s in remission now so he’s come out the back end of it, he’s recovered.
“He was a massive inspiration to me because when you see somebody who’s ill like that but still training and still working hard, it’s brilliant to look at them and think you’re dealing with something so severe like this.”
