The Sehgahunda Valley (“Vale of Three Falls”), which encompasses the portion of the Genesee River Valley, was comprised of several villages settled by the Seneca People. The locations of these villages make up the current boundaries of Letchworth State Park.
Letchworth State Park spans over 14,000 acres, with miles and miles of trails - all with varying degrees of technicality to challenge both experienced runners and casual hikers. Many of the trails that make up this race are the very trails used by the Seneca Indians to access the Genesee River, which bisects this valley, giving rise to its nickname “The Grand Canyon of the East.”
We dare you to experience the beauty, history, and challenge of this unique event!
