Competitors at the annual Raw Challenge Doyalson 2013, in New South Wales, Australia, got a little more than they bargained for when windy conditions blew over one of the obstacle slides. Known as the “Mud Slide”, the 25ft tall obstacle took off in the gust, though thankfully nobody was on it at the time. Raw Challenge Doyalson consists of a 6km course, boasting over 30 testing obstacles. Credit: JollyStunts.
