Star City San Bruno Mountain Half Marathon
The Excelsior Running Club presents the 8th annual Star City San Bruno Mountain event on October 3, 2026 in Brisbane, California. The start and finish are at the crosswalk at Visitacion Avenue and San Francisco Avenue in the village of Brisbane. The half marathon course is primarily on trails and reaches about 2,400 ft of cumulative elevation gain, while a 5K option has about 250 ft of gain.
The route begins on local streets, includes stairs, then moves onto fire roads and single-track trails that reach a summit with views of the Pacific, the Bay, and San Francisco. Runners encounter a long, fast single-track downhill of almost two miles and several rolling sections on the ridge before returning to Brisbane. The course is marked with red ribbons the night before and will have volunteers and cones at decisive intersections.
Aid stations are positioned along the half marathon (notably near 3.4, 7.4, and 10.1 miles) and are stocked with gels, water, and sports drinks. The event is a cupless race; participants are advised to bring a water bottle or collapsible cup. Sensitive habitat surrounds much of the course, and volunteers have the authority to disqualify anyone who leaves the trails.
Registration for the half marathon includes a t-shirt if registered by 9/20/2026, a finishers medal, and a meal. A portion of registration fees supports local community organizations. Visit the organization's website for the most recent information.
