The 50-mile course lists 11,100 feet of elevation gain and a 20-hour cutoff. The 100K follows the 50-mile course with an extension south of Granite Peak and remains primarily trail with minimal dirt-road sections.

The 50K (Sweet 50k) is a lollipop-style course with about 7,000 feet of elevation gain and a 12-hour cutoff. The 29K (Tall Trees) uses the out-and-back section to Granite Peak, with about 2,500 feet of vertical gain and an 8-hour cutoff. Herman's Half-ish is a point-to-point mostly downhill course with a 5-hour cutoff.

The memorial ruck relay is a 2-5 person relay over the 50-mile course.
