The race covers roughly 65 miles, climbing the Rim in three separate locations spending a lot of miles along the Rim, on top of the Rim and the challenging climbs up and down with climbs and descents at 30-45% grades at a some points. Expect to climb a total of approximately 13,000 feet along the way, never below 5,200 feet and never above 8,000 feet in elevation. While other races are certainly at higher elevations, and/or with more climbing, they certainly do not contain as rugged a terrain that is found on this course. This is a VERY technical course in many areas, specifically the Highline Trail, Donahue and the soon to be revered, Myrtle Trail. This is one of the most technical 100K’s in North America. That coupled with the terrain, moderate elevation, and intense Arizona sun, this race will certainly take its toll on each runner.
