Red Rocks of Sedona

Red Rocks of Sedona is held in Sedona, Arizona, on October 17, 2026. The marathon (26.2 miles) and the 20-mile (32.2 km) start together at 7:45 a.m., and the 10-mile (16.1 km) follows at 8 a.m. All three are trail races through the red rock country of northern Arizona, and Sedona itself sits well above 4,000 feet.

A trail marathon on this terrain is not a course for a personal best, and that is worth accepting before you start: your mile splits will be slower than on the road, and the sensible approach is to run by effort and hike the steep sections. The 10-mile is a good way in for anyone with a half marathon of road fitness. For the marathon or the 20-mile, build over twelve to sixteen weeks with weekly long runs on climbing terrain.
