The Rubicon

The Rubicon is a very difficult, remote on- and off-trail foot race set in the backcountry of the northwestern Sierra Nevada, near Oxbow Reservoir, California. It offers three route options: The Requisite (15+ miles, about 6,700 ft of gain, 3 hill climbs and 2 water crossings); The Resonant (30+ miles, about 12,700 ft of gain, 6 hill climbs and 6 water crossings); and The Revenant (43+ miles, about 19,300 ft of gain, 8 hill climbs and 8 water crossings). This is not an official event—there are no course markings, aid stations, staff, or medical support.

Completing The Requisite is required before attempting The Resonant, and The Resonant before The Revenant. Visit the organization's website for the most recent information.
