Welcome!

The Bay Area 100 is here! The Bay Area 100 isn't just a race—it's an epic odyssey through some of California's most breathtaking terrain. Starting beneath the iconic UC Berkeley Memorial Stadium on June 13, 2026, you'll embark on a 100-mile journey that will test every fiber of your being.

This isn't your average ultramarathon. You'll traverse the dramatic ridgelines of the East Bay hills, where panoramic views of Marin, San Francisco, the South Bay, Mt. Diablo and beyond will either inspire you to greatness or remind you just how small you are against nature's grandeur. Every grueling mile leads to moments of pure transcendence.
