Olympic rowing stars from the Westcountry swapped boats for beats in a bid to raise money for Children in Need.
Gold medallist Helen Glover, from Penzance, joined crewmate, Heather Stanning, from Yeovil, and Team GB members Katherine Grainger and Anna Watkins in a performance of street dance to be screened at the charity event next week.
Plymouth diving sensation Tom Daley also joined in the fun. The 18-year-old, who won a bronze medal at London 2012, has filmed a music video with his fellow Olympians to Basement Jaxx's song Do Your Thing for Children In Need.
He told the Radio Times: "As you can see, I'm not a great dancer.
"But I love making a fool of myself."
Also reflecting the British successes during the summer will be the Queen's granddaughter Zara Phillips, who will perform a musical dance routine which enjoyed phenomenal success and sparked dozens of celebrity imitations this summer.
The event rider, who is married to England rugby star Mike Tindall, will pick up the reins as a Gangnam Style dancer in a video for the BBC's marathon fundraiser on Friday night. She joined Team GB equestrian members Nicola Wilson and Tina Cook to perform the cheeky riding routine, originated by Korean star PSY, but copied by fans, including Boris Johnson and David Cameron.
