Formula One world champion Lewis Hamilton and Britain's triple Olympic gold medal-winning cyclist Chris Hoy will go head-to-head as part of the build-up to the Race of Champions at Wembley next month.
The race will take place on a parallel track with Hamilton driving a Mercedes-Benz and Hoy pedalling his bike.
Hamilton said: "This is going to be something very special. The atmosphere is going to be crazy. It's going to be a great way to end a fantastic year, and I'm really looking forward to putting on a show."
Hoy, who won gold in the keirin, sprint and team sprint in Beijing realises that although he can "kick out about two and a half brake horsepower" he will fail to meet the power of the car.
"I think they'll make the race as close as possible and I'll be giving it absolutely everything; I'm really looking forward to it."
Hamilton, who became the youngest driver to win the Formula One world title, will also perform a demonstration run in his title-winning McLaren.
The Race of Champions takes place on 14 December featuring the likes of seven-time F1 world champion Michael Schumacher and F1 race winners David Coulthard, Sebastian Vettel and Jenson Button.
