The event is a point-to-point Half Marathon held on Saturday, May 16, 2026, in Almaden Quicksilver County Park. The course begins at the Mt. Umunhum parking lot and descends to the Hacienda Entrance parking lot on Almaden Road.
The route covers approximately 13.4 miles with a total ascent of 1,909 feet. The first 3 miles are on single-track Mt.

The course includes toilets at the start, at the finish, and at all aid stations.
Aid and water stations are located at these approximate mile markers: Mile 3.2 (Mt. Umunhum and Barlow Trail intersection), Mile 5 (Sierra Azul Woods and Barlow Trail intersection), Mile 7.9 (Woods Parking Lot aid station), and Mile 10.9 (Mine Hill and Catamount Trail intersection). The Woods Parking Lot aid station and the finish both have toilets. Cutoffs will be strictly enforced and the race has a 5.5-hour time limit.
