Many On The Genny

Many On The Genny is an all-trail ultramarathon held in Letchworth State Park near Castile, NY. The course uses both sides of the park's gorge and travels across single track, open fields, footbridges, and bridle paths.

Runners encounter a variety of terrain and scenery, including notable vistas and steep, sustained climbs. The event is presented in the style of old-school ultras and emphasizes self-sufficiency on the trail.

Support on course includes five fully stocked aid stations and one water stop. Some remote sections of the route may require runners to cover up to eight to nine miles between aid points, so participants should plan for extended unsupported stretches.

Distances available:

  • 45 Miler
  • Many On The Genny RELAY

The event location is listed as 6103 Visitor Center Road, Castile, NY. The organizer describes the race as a grassroots, community-friendly event that focuses on trail running within the park. Visit the organization's website for the most recent information.
