One... Two... Three... GO!

Quick! Ring round your mates and rellies - you’re going to need a team of three for this mad and muddy caper.

Think of peeps who don’t mind getting their hands, face, arms, legs, feet and torso dirty. The types who are up for off-road running, mountain biking, kayak canoeing and a right good giggle.

They can be male, female or even a bit a both - ooh! And while none of you need be Olympians, you’ll have enough puff to run 10km and, between you, cover 25km in the saddle and about 1.5km on the water. (We’ll also be chucking in another couple of challenges. But we’ll tell you about those on the day).

Finally, your fellow team members will need a serious appreciation of breath-taking countryside and a bloomin’ good sense of humour. Oh, and they’ll need to be free at some point between 18th October 2009 and 21st March 2010 (depending on which of the four stunning locations you choose to take the challenge in)

So, who’s as crazy as you?!
