Event Overview

Welcome to The Big Alta presented by Goldwin! This event is the latest collaborative trail running experience from Freetrail and Daybreak Racing, located in trail-famous Marin County, California! With every step, these thoughtfully crafted single-loop courses provide an unforgettably scenic trail race experience. On the home trails of Freetrail, The Big Alta offers two race distance options: a tough, inspiring 50K, along with a shorter yet equally exhilarating 28K.

A feast for the eyes, these courses will treat runners to seemingly endless vistas that stretch across the entire San Francisco Bay Area. Both the 50K and 28K routes pay homage to course landmarks Loma Alta and Big Rock Ridge, two of the highest points in Marin County. The Big Alta will not only challenge its participants physically, but also reward their efforts with awe-inspiring views, heaps of trail community love and of course, all the electric race weekend vibes and hype!

Through the combined skillsets of Freetrail and Daybreak Racing, we will endeavor to deliver a premium quality race experience for our participants and volunteers, filled with spectacular views, challenging trails, good vibes, and an exciting finish line experience to celebrate human achievement. We hope you'll join us!

Land Acknowledgement: We honor and recognize that we gather for this event on the traditional lands of the native Coast Miwok people, who have occupied and stewarded these lands for countless generations.
