The 100-mile distance is an official Western States Endurance Run lottery qualifier for runners who finish within 32 hours. The race offers cash prizes for the 100M overall podium: $800, $400, and $200 for first through third in male and female categories. All finishers receive distance-specific awards: buckles for the 100M and 100K, medals for the marathon and half marathon.
Course, support and rules
The course uses a loop of about 16.7 miles on wide, mostly flat pathways. The route is described as 99.9% flat, with a single 10-foot rise; surfaces include hard crushed rock, soft shaded hiking trails, and smooth horse trails. There are four staffed aid stations on course (Elm Lake, 40 Acre Lake, Hale Lake, Sawmill) and an unmanned water at the Nature Center for shorter distances. Runners must carry their own hydration device; aid stations do not provide cups. Drop bags for Sawmill are accepted at Elm Lake during packet pickup. Pacers are permitted on final loops only (100M: final two loops; 100K: final loop). Special event park passes are required for attendees age 13 and older; state park camping must be reserved through the official reservation system.
