About This Race
The Sinnemahone Ultra Marathon stands as the culminating challenge of Pennsylvania's unique Sinnemahone Triple Crown, a year-long multisport series that tests participants across water, gravel, and trail. This 50K trail run through the forests of north-central Pennsylvania has built a devoted following since 2013, drawing runners who appreciate both the technical demands of the course and the intimate, community-driven atmosphere. What sets this race apart is its integration into a broader athletic narrative. Runners who complete the canoe race in April and gravel bike challenge in September earn the coveted Triple Crown distinction with their October trail effort. This context creates a uniquely motivated field where many participants arrive having already invested months in the series, fostering camaraderie and shared purpose that extends well beyond typical race day interactions. The October timing captures Pennsylvania's peak fall colors, offering runners a visual reward for their efforts through dense hardwood forests and rolling terrain. With over a decade of consistent operation, the race has established itself as a reliable fixture in the regional ultra calendar, though specific course details and elevation profiles require direct inquiry with organizers.
