    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!
