Bay Area 100
The Bay Area 100 is a 100-mile point-to-point ultramarathon held on June 13, 2026. The course starts at California Memorial Stadium at UC Berkeley and finishes on the track at Skyline High School in Oakland. The 2026 running is limited to 150 participants.
Course and entry details
The course includes about 18,000 ft of vertical gain and crosses East Bay ridgelines, redwood forest, and lake shore on fire trail. It passes through areas described as Bay View, Las Trampas, Lake Chabot, and Redwood territories. The event uses aid stations and has course cutoffs; a 33-hour overall time limit is applied.
Pre-registration reservations opened on September 1, 2025 and run through December 7, 2025. Pre-registration is offered at no charge while credit-card information is collected; a reservation gives first right of refusal to register and entrants have a week in December to confirm. The organizer recommends a recent 50-mile race as a qualifying performance; participants will be asked for the qualifying race, its date, and finishing time during pre-registration. Exceptions to the qualifying recommendation may be requested. The race is listed as a UTMB index event and is not a Western States qualifier in its first year.
