Warm start, big temp swing

A warm 73°F start means heat management is critical — consider dialing back your goal pace by 10-20 sec/mi. Temps will climb significantly to 90°F by later miles, so expect fading conditions as the race progresses. Light winds shouldn't be a major factor for pacing.

Race Info

The Six-O Trail Run 50K covers two clockwise laps of a roughly 15.5-mile loop at the Six-O Ranch, a working cattle ranch outside Cleburne, Texas. The loop mixes single track, dirt ranch roads and open-field crossings, with a couple of water crossings and about 1,300 feet of climbing on each lap. The 50K starts first on the Saturday of race weekend and shares the start and finish area with the shorter distances.
