This year’s Tamalpa Headlands 50K was another giant success,!  The race saw 274 starters with 258 finishers!   The 2026 Tamalpa Headlands 50k is in the records books now.  Tamalpa gives a giant congratulations to Race Director, Victor Ballesteros for pulling off another Hurculeneam accomplishment.  On behalf of the Directing Team, Course Director Ken Michal and Volunteer Director Lorna Doone our hearts are full with what an amazing day it was!

So many beautiful memories of the day for all the runners and volunteers! 

While it wasn’t a huge feild, it certainly was a stacked one! Sisters, Ada and Clara ran with unbridled energy holding tightly to mom’s hands! Even with a photo finish, it was too close to tell the victor. Both raised their hands as champions!

Originally founded in 1995 as the Pt. Reyes 50k and reimagined as the current course in 1998, the Tamalpa Headlands 50K presented by Arc’teryx and the Tamalpa Runners features many of Marin County’s most iconic and challenging trails: Coastal, Miwok, Matt Davis and Dipsea. The idyllic and beloved Santos Meadow near Muir Woods is the location of the start and finish line after-party.

Just a hop and a skip from San Francisco, the course traverses approximately 6,600 rugged feet of elevation gain featuring a mix of steep climbs, fast descents, flowy singletrack, and on a clear day, stunning views of the Bay Area, Pacific Ocean and beyond. You’ll experience all the splendor that the Marin Headlands and Mount Tamalpais has to offer in one of the country’s most stunning locations to celebrate the sport of ultrarunning.

NOTE: 

We WILL NOT BE the 2026 USATF 50k Trail Championship. The committee wanted to award it to an event that’s never held it before and we’re stoked to share the love! 

BUT, We WILL STILL be part of the USATF PA Grand-Prix.

And, once again, we’ll “show you the money!” with our $10,000 podium purse!!! Get in for the 27th edition of this Northern California Classic, because this party’s gonna’ blow up!
