Tamalpa Headlands 50K
Featuring many of Marin County's most famous trails: Coastal, Miwok, Steep Ravine, Matt Davis and Dipsea. The Tamalpa Headlands 50k, presented by NIKE Trail and the Tamalpa Runners of Marin, provides a spectacular setting for this classic, single-loop ultramarathon founded in 1998.
This year, not only are we the USATF 50k Trail National Champs, but NIKE Trail has thrown down with a spectacular podium purse that the race has never seen!
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.
