Event
The Bay Area 100 is a point-to-point ultramarathon of 100 miles held on June 13, 2026. The course begins at California Memorial Stadium at UC Berkeley and finishes on the track at Skyline High School in Oakland, California. The 2026 running is limited to 150 participants. Pre-registration reservations for 2026 open September 1, 2025 and run through December 7, 2025. Reservations are free but require credit card information and grant a first right of refusal to register; registrants have a week in December to decide. The organizer recommends a 50-mile qualifying race within the prior year and will request the race name, date, and time during pre-registration; an exception request option is available. The Bay Area 100 is listed as a UTMB index race and finishing times will be entered within two weeks of completion. It is not a Western States qualifier in its first year.
