About the race
Many On The Genny is a 45-mile all-trail ultramarathon in Castile, New York, set inside Letchworth State Park’s famed gorge. The course runs on both sides of the gorge, featuring single-track, fields, footbridges, and bridle paths, delivering stunning vistas and challenging climbs. The event preserves a grassroots, old-school ultrarunning vibe and emphasizes self-sufficiency.
Five fully stocked aid stations plus one water stop are spread along the distance, with longer gaps between some segments in remote sections. It celebrates rugged trail scenery, a supportive community, and the shared spirit of endurance running—a classic, self-supported challenge for serious trail runners.
