Reesor 50 Ultraranch Festival
The Reesor 50 is an unforgettable adventure through the rugged beauty of the Cypress Hills. The journey takes you across rolling meadows, winding trails, and beneath the towering conglomerate cliffs that stand as silent guardians of the land. Each step reveals new sights: wildflowers, grazing deer, and the calls of distant hawks. The terrain tests your endurance, with challenging climbs rewarded by sweeping vistas.
The race begins and ends at the Historic Reesor Ranch.
This event offers three distances, the Sundown 10 on Friday night, followed by the Reesor 50 and the Reesor Mountain Marathon on Saturday.
