Bay Area 100 - June 13, 2026
The Bay Area 100 is a 100-mile point-to-point ultramarathon that begins at California Memorial Stadium (UC Berkeley) and finishes on the track at Skyline High School in Oakland, California. The course accumulates about 18,000 feet of vertical gain and passes through varied terrain including exposed ridgelines, redwood forest, and lake-shore fire trails. It traverses areas identified as Bay View, Las Trampas, Lake Chabot, and Redwood territories.
The event has a 33-hour time limit and uses scheduled cutoffs; organizers provide detailed information about aid station locations, crew accessibility, and cutoff times. The race is a UTMB index event and finishing times will be entered within two weeks of completion. It is not a Western States qualifier in its first year.
Pre-race requirements include a recommended qualifying performance of a 50-mile race within the prior year; entrants provide their qualifying race and time during pre-registration and may request an exception. Pacer registration, Pacer Central, and Crew Central are active. The 2026 edition is sold out, with additional runners accepted from the waitlist as space becomes available. Related activities announced by the organizers include a Training Camp (April 17-19) covering 70+ miles with some free options, a Coaching Collab livestream beginning January 15, and a published athlete guide. The event is organized by Scena Performance. Visit the organization's website for the most recent information.
