COURSE

Set in Owen-Putnam State Forest and beginning at Horse Campground, runners traverse a 14-mile course consisting of 90% single track and horse trails with a few sections of fire road. The course is a lollipop: Start/Finish to Aid A is the “stick” and a loop from Aid A through Aid B and back to Aid A is the delicious “pop”. Aid A to the Start/Finish completes the lollipop. The 10K loop is a single loop.

Trails are rugged and there will be mud! It’s the toughest trail race in Indiana!
