Bay Area 100 - June 12, 2027
The Bay Area 100 is a point-to-point, 100-mile trail race in Berkeley, California, organized by Scena Performance. The course begins at the gates of California Memorial Stadium and traverses varied Bay Area terrain, including exposed ridgelines, redwood forest, lake shore fire trails, and sections through Bay View, Las Trampas, Lake Chabot, and Redwood territories. Runners encounter panoramic views that can include sights from the Golden Gate to Mt. Diablo.
The course profile includes approximately 18,000 ft of vertical gain and a 33-hour finishing time limit. The event uses cutoffs at intermediate points; aid station locations will be published in the 2027 Athlete Guide, available mid-August.
Entry is limited to a capped field of 300 runners. The organizer will use a staged registration process: pre-registration for deferrals and 2026 alumni, an open enrollment phase that admits up to 200 runners, and a waitlist with offers allocated on a specified date known as Waitlist Wednesday. After initial offers, a rolling waitlist will remain in effect. Entrants may defer their entry up to 30 days before race day, with deferrals rolling over to the next year.
The Bay Area 100 is designated as a Western States qualifier for 2028 and is listed on the UTMB Index. Visit the organization's website for the most recent information.
