Billed as "the toughest race in the world," the Tough Guy 2012 competition took place yesterday in Perton, England. Every year, thousands of men and women tackle the course, which is described on the Tough Guy website as eight country miles filled with freezing mud and "barbed wire, cuts, scrapes, burns, dehydration, hypothermia, acrophobia, claustrophobia, electric shocks, sprains, twists, joint dislocation and broken bones." Gathered here are some images of the fun had by the tough competitors in this year's event.
