Arches 50K
Race Day Weather
Cool start — fast day potential, big temp swing
A cool 46°F at the start line is ideal for fast times — expect to warm up quickly once you're moving. Temps will climb significantly to 67°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 Arches 50K is the longest distance on the Behind the Rocks Trail course south of Moab, Utah, with roughly 3,000 feet of climbing between about 4,500 and 5,700 feet. It runs sandy double track, jeep road and desert meadow trail, loops past Picture Frame Arch, and returns to the start and finish area after an added loop through the dunes. Runners get views of the La Sal Mountains on the climb to the first aid station.
