The Archers, Radio 4’s everyday story of country folk, has seen some pretty jaw-dropping cameo appearances in its 64 years on air.
Camilla Duchess of Cornwall, Princess Margaret, Dame Judi Dench, cricketer Mike Gatting, Terry Wogan and even Chris Moyles have all appeared in the veteran drama.
But an Olympic gold medallist Mod is a new one for the programme.
Cyclist Bradley Wiggins, Tour de France and four-time Olympic gold medal winner, recorded his appearance for Sport Relief.
He will make a cameo as himself in a special episode at 7pm on Friday 21 March, in which Sport Relief fever takes hold of the Archers village of Ambridge.
As the locals prepare for their own fundraising event, Sir Bradley arrives to crown the village winner – but not before the cycling hero has an amusing encounter with local busybody Lynda Snell and her rusty old bike.
Wiggins said: “When I was asked to record a Sport Relief special for The Archers, there was no way I could turn it down. I grew up with it on the radio in the house, and it’s not every day you get to star in the world’s longest running soap opera.
“Meeting the cast, the writer and the director was an honour and I really hope the story line will raise awareness about Sport Relief’s amazing work, and that it shows people that everyone can get involved in Sport Relief this year.”
The Sport Relief Games take place from Friday 21 to Sunday 23 March and Wiggins' appearance is designed to highlight the fact that the public will be able to take part in cycling events as well as running and swimming.
Since 2002, Sport Relief has raised over £195million to help people living in the UK and across the world.
