Many On The Genny

A 45-mile trail ultra using both sides of the famous gorge in Letchworth State Park. An all trail event, you will traverse single track, fields, footbridges, and bridle paths. You will experience beautiful vistas, quad-busting climbs, and most importantly a grassroots, community-friendly event.

In the style of old-school ultras, this race comes with a need for self-sufficient runners – We have 5 fully stocked aid stations and 1 water stop on the course spread out among the 45 miles. Be prepared to spend up to 8-9 miles between some of the aid stations in some remote sections of the trail.
