The Rubicon

About the event

The Rubicon is an arduous and remote foot race that challenges runners to push beyond their limits deep within the rugged backcountry of the northwestern Sierra Nevada. This non-sanctioned, self-supported adventure offers three distinct routes: The Requisite (approximately 15 miles with over 6,500 feet of elevation gain), The Resonant (over 30 miles and nearly 12,700 feet of ascent), and the grueling The Revenant (43+ miles and an astounding 19,300 feet of climb). Each route features multiple hill climbs and water crossings, with no course markings or aid stations to rely on. Runners must be prepared for a solo journey that demands meticulous planning and resilience. Drop bag locations are the only support provided along these treacherous trails, making The Rubicon an unparalleled test of endurance and self-reliance. For those seeking extreme challenges in one of nature's most unforgiving landscapes, this event offers an unforgettable experience on November 6, 2027.
Participants must complete the preceding shorter route before qualifying for a longer distance attempt in future editions.
