Terrain includes smooth singletrack, rocky sections, steeper climbs, and flowing descents. One aid station will be located at the Green Bridge. Parking is limited, and carpooling is suggested. Registration opens May 16, 2026, and race day registration will be available. Race swag is guaranteed for the first 200 registrants; remaining swag is first come, first served.
