The annual Baker Trail UltraChallenge is a 50-mile ultramarathon on the Baker Trail. Runners will follow the Baker Trail south for 40 miles to Summerville, then turn east to Brookville and end at the Brookville YMCA. The deadline for finishing is 8:30 PM. Individual and team relays of up to five members may register. Course is mostly a rugged hiking trail through the woods, over rocks, across creeks, and up and down hills, and along some paved and dirt roads.
