Course and logistics
Courses are primarily single-track trail in foothill terrain, with approximately 2,500 feet of elevation gain and sections of steep hills and rough footing. Aid stations are placed as follows: the 10K has one aid station near mile 4; the half marathon has aid stations around miles 4, 6, 9.6, and 11.7. Aid stations will offer water, sports drink, GU gels, Skratch, and snacks. Runners are encouraged to carry personal hydration and nutrition. The route will be marked with directional signs and orange ribbon. Parking is available near the start/finish in the Aholul Campground, in lower and upper lots, and on cleared roadside areas; participants are asked to carpool if possible and not to park in the equestrian area. Volunteers will direct traffic on arrival. Refreshments will be available after the race. Visit the organization's website for the most recent information.
