Event Overview

Welcome to The Big Alta, the latest collaborative trail running event from Freetrail and Daybreak Racing, 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 summit 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!
