The Race

Featuring many of Marin County's most famous trails: Coastal, Miwok, Steep Ravine, Matt Davis and Dipsea. The Tamalpa Headlands 50k presented by the Tamalpa Runners of Marin and UltraRunning Magazine provides a spectacular setting for this classic, single-loop ultramarathon founded in 1998.

Just a hop and a skip from downtown San Francisco, the Tamalpa Headlands 50k is a demanding ultramarathon with approximately 6,500-feet of elevation gain featuring fast fire road running, steep climbs, flowy singletrack, technical sections and stunning views of the Bay Area, Pacific Ocean and beyond. The idyllic and beloved Santos Meadow, just south of Muir Woods, is home to the start and finish after-party of the 22nd edition of this iconic Northern California Classic.

Please join us on Saturday, August 17th 2024, to enjoy all the splendor that the Marin Headlands and Mount Tamalpais has to offer in one of the country's most stunning places to celebrate the sport of ultrarunning.
