The Green Monster is a trail challenge designed for both runners and hikers of all ages and abilities, offering a 15k, 25k and Monsterous 50k option for the overachieving sadists among us. This course is nestled in the mountains of the Tioga State Forest just North of the PA Grand Canyon and is the mission of the Tyoga Running Club to showcase the beauty and difficulty of this terrain. You will be confronted with beautiful rolling single track trails, hellacious steep climbs, abundant stream crossings, and some gnarly technical descents - all of which add to your wild experience and the joy of dragging your haggard soul across the finish line! This course is not for the faint of heart and will challenge even the most conditioned athlete!
