Course and logistics

The main event is a 45-mile trail ultra that uses both sides of the gorge in Letchworth State Park. The course is entirely on trail and includes single track, fields, footbridges, and bridle paths. The route contains viewpoints and steep climbs in places. The event provides five fully stocked aid stations and one water stop on course. Some remote sections place aid stations up to 8-9 miles apart, requiring participants to be prepared for long sections without support. The event is organized in a grassroots community style.
