The inaugural Dipsea 10 Mile has been added to the Enviro-Sports trail series. This event will feature the iconic Dipsea trail as you traverse Mt. Tam from Stinson Beach to Muir Woods and back. The entire route stays within GGNRA, Mt. Tamalpais State Park and Muir Woods National Monument and includes the panoramic vistas, redwood and oak forests, challenging hill climbs and descents and landmarks that the Dipsea trail is noted for. There will be one major difference between this event and the annual Dipsea and Double Dipsea races: There will be no age handicaps for the start. The fastest runners will start up front and slowest in the back making for a much safer race as there should be minimal passing on the narrow sections of the trail. We look forward to welcoming you to this new classic event.

CANCELLATIONS: Registrations are non-refundable and non-transferable, unless you choose to protect your purchase with the optional “Purchase protection policy” offered at checkout. You can read the protection policy terms online here. Even if you choose to purchase it, you have 72 hours to cancel the policy if you decide you don’t want it. But you cannot purchase it AFTER you have completed your checkout. Otherwise if you email us by September 15, 2023 you may receive a rollover credit (the amount you paid minus a $20 fee) to use toward any future Enviro-Sports race.

HEADPHONES POLICY: 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.
