Are you tough enough?

Tough Mudder is a series of hardcore obstacle races designed by the British Special Forces to challenge the toughest of the tough. Obstacles include crawling under razor wire, scaling inverted fences, reaching the summit of "Mount Everest" and getting a buzz out of electroshock therapy.

Sound too tough? Give the Tough Mudder 5k a go – a 5k obstacle course without fire, ice or electricity, it’s all the mud and a third of the distance. Are you tough enough to join the team?
