Many On The Genny

Many On The Genny is scheduled for June 20, 2026, at Letchworth State Park in Castile, New York. The main event is an approximately 45 mile all trail ultra that uses both sides of the Genesee River gorge. The course runs on single track, fields, footbridges and bridle paths and includes notable climbs and scenic vistas.

Distances and options:

  • 45 mile trail ultra
  • Many On The Genny RELAY

The event follows an old school self sufficient approach. There are five fully stocked aid stations and one water stop spread along the route; runners may travel up to nine miles between some service points in remote trail sections. Time cutoffs apply at each aid station and the official finish requires completion within 14.5 hours or less. The field is capped at 150 entrants and a wait list is maintained.

The race is presented as a grassroots, community oriented event focused on trail running through Letchworth State Park. The course surface and remote sections make planning and self support important for participants. Visit the organization's website for the most recent information.
