RUN FOR REGIONAL PARKS

Calling all runners, walkers, hikers and nature enthusiasts! Get ready for an exhilarating day of Lakeside Laps at Lake Chabot—a celebration of wellness, community, and the beauty of the East Bay Regional Park District!

Since 2010, this signature summer race (AKA "The Bad Bass Trail Runs") has been a cherished tradition.

This year's event promises to be extra special as we mark the 90th anniversary of the East Bay Regional Parks District and support the invaluable work of the Regional Parks Foundation.

Here's what's in store for you:

  • Scenic Routes Immerse yourself in the tranquility of nature as you run along the picturesque shores of Lake Chabot. Every step is a reminder of the breathtaking beauty that surrounds us.
  • Multiple Distances Whether you're aiming for a half marathon, 10K or a 5K “Trout Trot” sprint, Lakeside Laps has a race for every level of runner. Choose your distance and prepare for an unforgettable journey.
  • Festive Vibes Experience the thrill of accomplishment and the joy of camaraderie as you cross the finish line. Lakeside Laps is more than a race—it's a celebration of community, friendship, and the shared love of outdoor adventure.
  • Supporting Our Parks Nature is essential.  By participating in Lakeside Laps, you're not just challenging yourself—you're also contributing to conservation and access for all to our beloved East Bay regional parks. Together, we can ensure that our communities coexist with the beautiful nature and habitats that we rely on.
