Race at the Rez
This amazing run course around the Boulder Reservoir is astonishing and remains mostly on dirt roads and trails. The course is flat with only 200 feet of elevation gain. The route will take you around the the Boulder Reservoir, where you will experience iconic views of the mountain range to the west.
The Half Marathon will complete 2 loops, and the 10K will complete one loop. 5K runners will run counterclockwise for 1.55 miles and then head back to the finish line in the parking lot area.
Aid Stations will be stocked with water, gels and a hydration drink. Snacks, music and other goodies will be available at special aid stations. Fluids will be available in small disposable cups, though the aid stations will be happy to refill your own water bottle as well, should you chose to carry one. Please dispose of cups in designated drop areas. We are a green event that will recycle all cups after the race!
Aid Station Mile Markers along the course: 1.0, 2.0, 3.1, 4.2, and 5.
Remember, the Half Marathon course makes 2 laps around the Rez, so you will hit these aid stations multiple times during the Half Marathon.
