Prepare for an unforgettable challenge at the Many On The Genny, a 45-mile ultra that plunges runners into the breathtaking "Grand Canyon of the East" – Letchworth State Park in Castile, NY. On June 20, 2026, you'll embark on a demanding journey across both sides of the Genesee River gorge, tackling upwards of 6,000 feet of elevation gain. The course is an all-trail event, with approximately 90% off-road, guiding you over diverse terrain including single-track, fields, footbridges, and bridle paths. While the first half of the race is known for its scenic beauty and runnable sections, don't be fooled; veteran runners warn that the second half "beats you up" with relentless, quad-busting climbs and remote stretches where a steady rhythm is hard to find. Typical race day conditions in late June bring highs around 80F and lows around 57F, with a 16% chance of precipitation, so prepare for varied conditions amidst stunning waterfalls and panoramic vistas.

Many On The Genny offers a true "old-school ultra" experience, emphasizing self-sufficiency and community spirit. The race features five fully stocked aid stations and two micro-stations, but with distances of up to 8-9 miles between some stops in remote sections, strategic hydration and nutrition are key. Aid stations provide standard ultra fare like chips, pretzels, and electrolytes, and runners are expected to be cupless, bringing their own hydration vessels. This grassroots event, directed by Eric and Sheila Eagan of #TrailsRoc, prides itself on a community-friendly atmosphere, and uniquely, encourages runners to express gratitude by "chucking an aid station"—leaving thank-you notes for the dedicated volunteers. No pacers are allowed, reinforcing the independent spirit of this capped field of 150 runners, and all proceeds directly support trail building and maintenance within Letchworth State Park.

The race starts promptly at 5:30 AM at the Mount Morris Dam Visitor Center, which also serves as the festive finish line. Here, after conquering the challenging loop, you can celebrate your accomplishment with fellow ultrarunners, enjoying post-race vegan "Garbage Plates" from Dogtown and refreshing craft beer from Genesee Brewing Company. With a hard cut-off of 14.5 hours at 8:00 PM, Many On The Genny promises not just a race, but an immersive journey through one of New York's most spectacular natural wonders, culminating in a well-earned celebration.
