Bay Area 100

Bay Area 100 is a 100-mile ultramarathon that runs point-to-point through the East Bay. The 2nd running is scheduled for June 12, 2027, with a 33 hour finish cutoff. The course includes roughly 18,000 ft of vertical gain and traverses ridgelines and redwood sections with variable weather and long views that can extend from the Golden Gate to Mt. Diablo.

The start location is at the gates of California Memorial Stadium. Course materials from 2026 included routes, pace charts, and GPX files. The 2027 Athlete Guide will be published in early November.

A Coaching Collab program offers recorded 30-minute sessions led by coaches that provide training and racing guidance; those sessions are available on the race YouTube channel. The organizers plan to expand the Coaching Collab for 2027.

A Training Camp is scheduled April 16-18 and covers three days of running on the course, including a Saturday night gathering at Sports Basement. The event is listed as a 2028 Western States qualifier.

Additional race content includes race videos and published race results and photos. The event has multiple sponsor partnerships noted by category such as footwear, hydration, nutrition, gear, and apparel. Visit the organization's website for the most recent information.
