The Big Alta

Event Overview

Welcome to The Big Alta, a collaborative trail running event from Freetrail and Daybreak Racing, in trail-famous Marin County, California! With every step, these thoughtfully crafted courses provide an unforgettably scenic trail race experience. On the home trails of Freetrail, The Big Alta offers three race distance options: a tough, inspiring 50K single loop, a world-class point-to-point 100K, along with a shorter yet equally exhilarating 28K single loop. A feast for the eyes, these courses will treat runners to seemingly endless vistas that stretch across the entire San Francisco Bay Area. All three courses summit many 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 support, along with all the electric race weekend vibes and hype!
