Gabby Logan is to host a one-off revival of 1970s TV hit Superstars, featuring gold medal-winning Olympians Mo Farah, Katherine Grainger and Jade Jones.
Medallists from Team GB are taking part in a BBC One Christmas special of the show which will also see triathlete brothers Alistair and Jonathan Brownlee going head-to-head once more.
Gabby - whose footballer father Terry Yorath once took part in Superstars - said it was one of her favourite shows as a child.
"I am thrilled to be hosting this special edition of Superstars. We have an incredible line-up of Olympic heroes. What an opportunity for them to compete against each other across a range of diverse physical challenges," she said.
The 16 competitors - who also include boxers Anthony Joshua and Nicola Adams - will tackle eight events, in a bid to be crowned the best male and female all-rounders in the Superstars 2012 programme.
Mo - who has already shown his abilities in TV challenges after competing in ITV1 show The Cube - said: "After a hard season it will be nice to compete in a different environment. Some of the events are quite new to me which will make it all the more interesting."
The show, filmed in Bath, will feature track races over 100m and 800m, archery, javelin, a 50m swim, a kayak race, a cycling hill climb and the challenges in the gym tests.
Superstars was a huge hit when first broadcast in the 1970s and continued into the next decade with occasional revivals over the years. It provided thrills and spills when Kevin Keegan had a nasty crash during a cycling heat, hurdler David Hemery injured his ankle during a fall in the steeplechase, and squash player Jonah Barrington stormed out after his squat thrusts failed to meet the judges' approval.
For this year's Olympic special, swimmer Rebecca Adlington will mentor the athletes in the pool and pundits will include athletes Iwan Thomas and Denise Lewis.
