Bay Area 100
Bay Area 100 is a 100-mile point to point ultramarathon in the East Bay, scheduled for June 12, 2027. The race starts at the gates of California Memorial Stadium and covers about 100 miles with approximately 18,000 ft of vertical gain and a 33 hour finish limit. The course runs across ridgelines and through redwood sections and exposes runners to variable weather and long panoramic views that can include the Golden Gate and Mt. Diablo.
The event is listed as a 2028 Western States qualifier. Organizers publish course materials that include routes, pace charts, and GPX files from the 2026 course; an Athlete Guide for 2027 is expected in early September. Supporting programs include a Coaching Collab of 30-minute sessions led by master coaches that provide guidance on building training and racing plans, and a Training Camp consisting of three days of running on the course with a Saturday night gathering at Sports Basement. The Training Camp and coaching sessions are presented as resources for participants preparing for the race. Visit the organization's website for the most recent information.
