Course, support and race features
The course is described as almost entirely flat with an approximate loop length of ~16.7 miles composed of hard crushed rock, soft shaded hiking trails, and smooth horse trails. Under dry conditions many runners choose road shoes. The event uses four staffed aid stations on course and a main start/finish aid area. All runners must carry their own hydration device; aid stations will not provide cups. Drop bags, pacer rules, and crew access are specified: pacers are allowed for the final loops of the ultra distances, while pacers are not permitted in the marathon and half marathon. Crew access to aid stations is limited and crew may not use aid station supplies. Finishers receive event-specific awards, and a cash prize purse is listed for the 100-mile event. Special event park passes and camping rules apply for park entry and overnight stays. Visit the organization's website for the most recent information.
