From the start at Rock Springs, the course follows Ridgecrest Blvd. along the spine of Bolinas Ridge separating East and West Marin County. 10K runners will take a left at Willow Camp Trail and head back to Rock Springs along the Coastal Trail. The Half Marathon course continues along Ridgecrest Blvd. to Bolinas/Fairfax Road and also returns via the Coastal Trail. The event is limited to 300 participants so don't wait too long to register!

Waiting at the Stinson Beach start line will be the only time you spend at sea level during this challenging trail run. From the word "Go" you'll be heading, up, up and away into the thick wooded trails of Muir Woods. You'll follow the legendary Dipsea trail to Steep Ravine, where you'll climb a wooden ladder, march up natural rock and wooden staircases and scramble under tree trunks. Along the way, enjoy the sounds of babbling brooks and waterfalls. Drink in the fresh smell of the towering redwoods and oaks that surround you. Your summit will be rewarded with panoramic vistas as you begin your descent back into Stinson Beach. The event is limited to 300 participants so don't wait too long to register!
