Race Details

A trail half through the Marin Headlands: coastal singletrack, big views, one honest climb, and a finish at San Francisco Running Company. Every registered runner gets a training plan and coaching from Integrated Stride, 20 childcare grants are on offer, and there's a $25,000 prize purse.

Spots are limited and the race is close to selling out. If you can't run it this year, we'd love your help on race weekend.
