Course, logistics and services
The trail passes through meadows, creek crossings, scenic overlooks, and a large granite dome, including exposed granite sections where participants may need to carry water. Course markings include caution tape, arrows, and confidence markers; markings are not color-coded by distance, and signs indicate the correct route at intersection cutoffs. Aid stations are staffed at the start/finish/next-lap location and at JACK A.S.; ROAD A.S. and GATE A.S. provide at minimum water, Tailwind, ice, and snacks. Some unstaffed stations may not have ice all day. Drop bags may be placed at the lake area and at the 360 Bridge/GATE spot; participants must deliver and retrieve their own items. All races are chip timed with ankle-mounted chips that must be worn on the ankle and returned if a runner leaves the course. Pacers are allowed under specified rules; overall awards include top finishers and masters categories. Camping and day-use fees apply at the ranch.
