Course, aid stations and logistics

The 100 Mile course combines one 22.3-mile loop and four 19.45-mile loops; the 100K uses one 22.3-mile loop plus three 19.45-mile loops; the 31K is a single loop. Each loop includes four on-course aid stations: Javelina Jeadquarters, Coyote Camp, Jackass Junction, and Rattlesnake Ranch. Longest aid gaps noted are about 6.5 and 6.6 miles; the organizer recommends carrying at least two water containers for those stretches. The course is marked with orange ribbon (black polka dots), blue-and-white ribbon at non-race junctions, and yellow logo signs; reflective markers are added for night sections. Crewing is permitted only at Javelina Jeadquarters; pacers must be human, on foot, one at a time, and follow the event’s pacer rules. Two drop-bag locations are available (Jeadquarters and Jackass Junction) and drop bags must be labeled. The event is cupless - runners must carry their own reusable cup or bottle. Medical support is available at Jeadquarters, Jackass Junction, and on course. Visit the organization's website for the most recent information.
