Challenging hills, paired with stunning views of both the Stinson Beach coastline and the immense, dramatic trees and landscapes of Muir Woods National Monument, await runners at the Muir Woods Marathon, Half Marathon and 7-Mile run, which marks its 31st annual running but makes just its 8th annual running with the 13.1-mile distance this year.

Muir Woods Marathon routes

Icon
The course will be marked with orange ribbon. The 7 Milers will turn at the first aid station. The half marathoners and marathoners will continue to do a loop. The marathoners will do that loop twice and an additional out & back with a sign at the out & back turnaround.

Organizers say that “from the word ‘Go,’ you’ll be heading up” — and they’re right. The course rises more than 1,100 feet in the first three miles, as runners climb through the old-growth redwood forests of Muir Woods, march up both rock and wooden staircases and even climb a wooden ladder from one trail to the next.

FAQs

What is the climate like in the area?

Nestled along the Northern California shoreline of Bolinas Bay, about 15 miles from Sausalito and roughly 24 miles northwest of downtown San Francisco, Stinson Beach typically sees much drier weather in May than in the previous winter months, and has seen record temperatures here as low as 23°F (in 1999) and as high as 102°F (in 2001).

Is there a time limit?

Runners will have 6.5 hours to complete the race.

Can I wear headphones?

Since parts of this race include very narrow trails with steep drop-offs along the course, it is imperative that runners can hear each other in order to pass safely, even if they are running at a slow speed. For safety reasons (and for the enjoyment of your fellow runners) headphones (and any other audio devices) are NOT allowed.
