Hundreds of contestants, from top cross-running athletes to  couch potatoes gathered in Peats Ridge for the first Mud Run race in Australia. On December 5, over 750 Aussies showed up in Glenworth Valley to participate in one of the dirtiest races on Earth. Each of the two available courses (one 6 km, the other 12 km long) featured mud pits, bog-holes, mud rivers, grasslands and creek crossings. The 2009 Mud Run in Peats Ridge was meant to be a competition for everyone, so any person over 12 years-old was free to register and because there was no time-limit they could run or walk the entire race. Competitors were encouraged to enter the Mud Run for a chance to help their favorite charity. Getting down and dirty Down-Under, now that’s got to be a memorable experience. via Zimbio Photo by Robert Gray/Getty Images AsiaPac Photo by Robert Gray/Getty Images AsiaPac Photo by Robert Gray/Getty Images AsiaPac Photo by Robert Gray/Getty Images AsiaPac Photo by Robert Gray/Getty Images AsiaPac Photo by Robert Gray/Getty Images AsiaPac Photo by Robert Gray/Getty Images AsiaPac Photo by Robert Gray/Getty Images AsiaPac Photo by Robert Gray/Getty Images AsiaPac Photo by Robert Gray/Getty Images AsiaPac Photo by Robert Gray/Getty Images AsiaPac Photo by Robert Gray/Getty Images AsiaPac Photo by Robert Gray/Getty Images AsiaPac Photo by Robert Gray/Getty Images AsiaPac
