Arches Half Marathon

Half Marathon and 10K

formerly The Other Half

October 11, 2020

Moab, Utah

Start Time: Half Marathon- 8:10 a.m, 10K- 8:45 a.m.

Course Description

The half marathon race starts at the gravel lot northeast of Moab.  The course parallels the river, amid backdrops of gorgeous scenery, including prominent landmarks Fisher Towers, Castle Rock, and the snow-capped La Sal Mountains. The course is out and back, with miles 8-12 contain some short hills and mile 13 is a fast downhill to the lush green finish at Sorrel River Ranch Resort.

The 10K race starts at the gravel lot and finishes at Sorrel River Ranch, on an out and back course. 

Aid Stations

Located every 3 miles, along the course. We highly recommend that runners race self-supported, as they will have to wait in line at the aid station, to get aid. There will be cones at each aid station, to indicate line up area. Please be patient, as we must social distance in a safe manner to meet all safety guidelines. 

Aid station supplies include:

  • water

  • Gatorade Endurance Formula

  • port-a-potties.  


Medical staff is stationed along the course and at the finish line.

See Google Map, at the bottom of this page, for locations.

Time Limit

There is a time limit of 3 hours and 30 minutes (16 min/mile pace). 

Due to safety concerns and permitting requirements, Arches Half course will have strictly enforced cutoff times at miles 2, 6, and 10. A pace of 16:00/mile or faster will meet the cutoff times. A cushion of 3 minutes is built into the cutoff times to account for the time it takes a runner at the 10+ min/mile pace signs to cross the starting line after the gun has gone off.
