The 300-participant Coastal Ridge Trail Run at Mt. Tam is a rare opportunity to enjoy trails and views of the Pacific Ocean with a close-knit running community.

Beginning at Rock Springs, the Half Marathon and 10K courses combine single-track dirt trails and paved roadways with the Marin County watershed’s mountain and ocean views.

Prepare for a trail running experience that’s nothing short of breathtaking – the Coastal Ridge Trail Run is back, and it’s promising a day of exhilarating adventure and unparalleled views. If you’ve been waiting for the perfect opportunity to lace up your running shoes and explore the stunning landscapes of Mt. Tam, this is it.
Nestled high up on Mt. Tam, this coastal ridge trail run takes you through rolling singletrack, offering vistas of the Pacific Ocean that will leave you awe-struck. It’s an event that combines the best of both worlds – the tranquility of dirt singletrack trails and the picturesque beauty of paved roadways.
As you start your journey at Rock Springs, you’ll be greeted with panoramic views of Bolinas Lagoon, the Pacific Ocean, and the pristine Marin County watershed. The course follows Ridgecrest Blvd., tracing the spine of Bolinas Ridge, which separates East and West Marin County. It’s a route that’s designed to immerse you in the natural beauty of the area, making every step a delight.
For those tackling the 10K race, your journey will take you on a memorable adventure. After following Ridgecrest Blvd., you’ll turn onto the Willow Camp Trail, guiding you back to Rock Springs along the enchanting Coastal Trail. It’s a route filled with surprises and opportunities to connect with the beauty of nature.
If you’re up for a bigger challenge, the Half Marathon course awaits. It continues along Ridgecrest Blvd., leading you to Bolinas/Fairfax Road. The return journey is equally spectacular, as you make your way back via the Coastal Trail, a path that promises even more breathtaking views.
What sets this year’s event apart is its exclusivity. The Coastal Ridge Trail Run is limited to just 300 participants. With such a small and intimate gathering, you can expect a more personal and memorable experience. It’s a rare opportunity to enjoy the serenity of the trails and the views of the Pacific Ocean in a close-knit community of fellow trail runners.
