Course and race details
Each loop starts at the Pavilion inside the park. The park contains 30+ miles of trails ranging from carriage roads to technical singletrack. The loop includes an initial 5 miles of mostly runnable rolling singletrack with a few small rock scrambles, then a steep rock scramble of 500+ feet in about 0.3 miles. The route continues on the Yellow Trail toward the Chestnut Trailhead, which is the location of an aid station at mile 8, and returns past the same aid station at mile 12. A later ascent follows the Quinnipiac (Blue Trail) to the Observation Tower, then a 1.5 mile carriage road descent on the Tower Path and a final 0.2 mile climb back to the pavilion. The organizer notes the 25K loop includes 3K+ of vertical.
