Green Monster Trail Challenge 2026

The Green Monster Trail Challenge is a trail race and hike in Wellsboro, Pennsylvania, offering 15K, 25K, and 50K distances, all starting from Straight Run Road. The name aligns with the distances: the 15K gains approximately 1,700 feet, the 25K gains approximately 4,000 feet, and the 50K gains approximately 7,800 feet. The 50K begins first in the morning, followed by the 25K, and then the 15K, structuring the day around distinct distances within the same mountain environment. The routes traverse the trails of Tioga State Forest, providing participants with maintained aid stations instead of a basic backcountry experience. Registration is limited to 350 runners, making it a more intimate event compared to larger trail races and emphasizing the importance of early sign-ups. Following the race, the venue transitions to include lunch, music, entertainment, event merchandise, and finisher awards, fostering a comprehensive post-run gathering rather than an immediate departure.
