Overview
Course Description
The park offers courses that are great for novice and experienced trail runners, with rolling landscapes, roots, and rocks. The 50M and 50K races begin at 6 am (before sunrise), so runners need headlamps or lighting. The 20M, half marathon, and 10K races start at 8 a.m. The longer distances are looped, with 50M/50K participants completing multiple 10-mile loops, including an additional loop around the open field for the 50K. The 20M runners will run the 10-mile loop twice. The half marathon and 10K participants will follow a 10K loop, with half marathoners doing an additional loop around the open field at the start. There are regularly placed aid stations on the courses that have vegan-friendly options. The race is held on traditional Musketaquid Indian lands and offers many community and inclusivity initiatives, including partnerships with the USATF Mountain/Ultra/Trail Running Youth Initiative for discounted youth entries, Trail Sisters for equal opportunities and amenities for women participants, and Pride on Foot for inclusivity of transgender and non-binary participants.
