Get ready for an unforgettable trail running experience at the Stinson Beach Half Marathon and 7-Mile on May 9, 2026, in picturesque Stinson Beach, California. This challenging event, celebrating its 36th annual running, plunges you into the breathtaking landscapes of Muir Woods National Monument, starting and finishing at Stinson Beach Park. With typical race day conditions seeing highs around 72°F and lows around 49°F, and only a 4% chance of precipitation, the weather often complements the stunning scenery.

Prepare for a demanding course that promises to test your limits. Right from the start, you'll embark on a significant ascent, gaining over 1,100 feet in the initial three miles and tackling a total elevation gain of approximately 4,790 feet for the half marathon. The entirely unpaved trail leads you through old-growth redwood forests, up natural rock and wooden staircases, and even requires navigating a wooden ladder and scrambling under tree trunks. As you climb, you'll be rewarded with panoramic vistas of the Stinson Beach coastline and the majestic Muir Woods, a landscape so iconic it served as a filming location for "Return of the Jedi." The course features abundant waterfalls, creeks, and the fresh scent of towering redwoods and oaks, offering a serene escape amidst the physical challenge.

This limited-entry race fosters a strong sense of community, with a cap of 300 participants across all distances. Aid stations, located at miles 3.8, 7.5, and 10.5 for the half marathon, are well-stocked with essentials like Gu products, trail mix, pretzels, PB&J, and Skratch Hydration Mix, along with general first aid. However, this is a cupless event, so runners must carry their own water bottles or reusable cups. Previous participants rave about the amazing views and positive atmosphere, noting the friendly people and encouraging vibes on the trails. Whether you're navigating the steep uphills or flying down the descents, the Stinson Beach Half Marathon offers a uniquely challenging and incredibly rewarding journey through one of California's most beautiful natural treasures.
