Big Bear Tough Mudder 2026
September 12

The Big Bear Tough Mudder brings obstacle course racing to Bear Mountain at 8,200 feet elevation in the San Bernardino Mountains, with 5k (12+ obstacles) and 10k (20+ obstacles) distances on the mountain’s rugged terrain. Named obstacles include Block Ness Monster, Funky Monkey, and Devil’s Beard — all with the altitude working against you. There’s no competition and no timing; it’s a team-oriented event focused on getting through the course together. Finishers earn a medal, shirt, and the iconic orange headband, plus a beer or seltzer at the finish. A Mudder Village with spectator access and live entertainment runs alongside the event.
