Are you tough enough for 'The Challenge'?Ever watched elite athletes climbing the worlds' toughest mountains, racing rally cars through the desert or trekking to the North Pole and thought, "I could do that."
Now's your chance to prove it...
BBC Television is looking for Britain's fittest and mentally toughest athletes to take on the biggest challenges in the world of adventure sports and they think some of their toughest challengers could come from the world of mountainbike racing.
Have you got what it takes to attempt a trans-Atlantic yacht record, run a 200 mile desert ultra-marathon or race non stop for 5 days and nights through the frozen Yukon?
If you think you have and you're over 18 years of age (male or female), write with a short biog and a few lines on why you're up to The Challenge to:
