Registration is open for the 2026 races; pre-registration is encouraged because the event has limited capacity. Registration fees vary by distance and age and include a well marked course, stocked aid stations, professional chip timing, post-race food, and post-race beer for participants 21 and older. A commemorative gift is provided to all racers; the gift is only guaranteed for registrations completed before July 1, 2026. Packet pickup is handled at Slopeside Hall, and all participants must complete an online waiver to receive a bib.

Course marking will use pink flagging and directional arrows, with course marshals at key junctions. Aid stations are stocked with water, Skratch hydration mix, fruit, and prefilled single-use cups containing snacks; 10k runners have two aid stations, half marathon runners have three, and 5k runners have no aid stations. The races are chip-timed by a professional timing service. Runners should expect mountainous terrain, variable weather, and shared public trails; strollers and pets are not permitted on race day. The 10k and half marathon have an official cut-off time of 10:30am. Visit the organization's website for the most recent information.
