The forested slopes and steep, cool canyons of Huddart Park and Purisima Creek Redwoods Open Space Preserve comprise a trail running paradise within the heart of the San Francisco Peninsula. Participants will enjoy the beautiful trails under the canopy of towering 2nd and 3rd generation, moss covered redwoods as they clip past the many small streams and gullies along the way. As runners make their ascent, they’ll enter the mixed evergreen forest, which leads to the drier Chaparral and Manzanita covered area of the ridge-line. Intermittent views offer well-deserved rewards throughout the twisting single-track trails and hills, which including the renowned Crystal Springs and Skyline Trails. Keep your eyes open, as you’ll probably be sharing the trails with black-tailed deer, coyotes, bobcats and gray foxes. Distances of 10K, Half Marathon, 35K and 50K make for the perfect proving grounds for runners, and hikers, of all abilities–from the first time trail runner to the grizzled, ultra-marathon veteran.

Sorry, no dogs are allowed in the park or on the trails.
