Experience a uniquely strategic and joyful running format along the stunning San Francisco Bay at the **Marina Double and 10K on Saturday, March 21, 2026**. This vibrant event, part of the official Double Road Race Federation series, invites runners of all abilities to choose their challenge on a famously flat, fast, and beautiful paved course on the Bay Trail.

Starting and finishing at the Brisbane Marina, the route offers breathtaking waterfront views, passing by multiple marinas and providing the perfect early-spring racing conditions.
More than just a race, it's a festive community celebration complete with medals for all finishers, quality shirts, age-group awards, cash prizes for Double winners, and plentiful post-race food and raffles. The professionally organized schedule ensures a seamless experience from packet pickup to the final celebration, making it an ideal event for families, first-timers, and competitive runners seeking a personal best on a guaranteed PR course. By joining this Bay Area tradition, you become part of a welcoming running community dedicated to fun, fitness, and fantastic scenery.
