About the race
The 2026 Stinson Beach/Muir Woods Marathon, Half Marathon & 7 Mile is a challenging trail event launching from Stinson Beach Park in California. Runners follow the Dipsea Trail into Muir Woods, ascending to Steep Ravine where a wooden ladder and natural stairways test movement among towering redwoods and oaks, with streams and waterfalls adding atmosphere along the way. Distances offered are marathon, half marathon, and 7 miles, with a field limited to 300 participants.
The course features loops and an out-and-back segment, marked by orange ribbons and multiple aid stations. Headphones are not allowed for safety, and finishers receive medals for the marathon and half marathon, plus a participant T-shirt. Visit the organization's website for the most recent information.
