The Dirty Burg is held at Cannonsburg Ski Area in Southwest Michigan. What makes this race special is the ski hill! The course is a 10k loop consisting of about 5.5 miles of beautiful rolling single track plus a .7 mile run up and down the ski hill. The 5k is the same loop with a shortcut and includes the ski hill at the end. 25k runners do one 5k loop and two 10k loops. 50k runners get to do the 10k loop five times!
