Course and logistics

All races start with a 3/4-mile out-and-back loop around the lake. The route then climbs Green Valley Lake Road onto Forest Service Road 2N13, with a roughly 400 ft climb to a viewpoint near the 5K turnaround. The surface is partly paved (about 1.5 miles) and then transitions to dirt roads and trail. The 10K extends about 1.55 miles beyond the viewpoint before returning. The half marathon follows an out-and-back route that reaches a high point with an additional short scramble trail to a viewpoint; the half marathon includes multiple aid stations on course. Water and aid stations are placed approximately every 1.5 miles. Chip timing will be provided by Itz About Time. Prizes include top-three overall awards per distance and age-group medals 3 deep in five-year spans up to 80+. Prices are listed per distance on the event page.
