Lake Chabot, where the race takes place, is a 315-acre lake whose history dates back to the 1870s, when it was built as a primary water source for nearby towns in the East Bay. While today it’s a popular place to go fishing, hiking, boating, swimming, golfing and canoeing — as well as running and cycling along its trails — what is now the park was closed for more than 90 years, until it was opened up for recreation in the 1960s.

Today, of course, it’s home to more than 20 miles of walking, hiking and bicycling trails, and it’s along these that you’ll run the race, starting near the southern end of the lake, where the park’s West Shore Trail and East Shore Trail meet. From there, you’ll follow a clockwise route along the shore of the lake, passing by the dam, the Lake Chabot Golf Course, some Castro Valley neighborhoods and more, all with the area hills off in the distance. Here’s how the race organizers describe it: We cannot promise you’ll encounter any cryptic, aquatic creatures at Loch Chabot, but you might! We DO promise a gorgeous trail run on the scenic trails of Loch Chabot Regional Park, some quality nature therapy, and some incredible views! If you’re not up for running the event in person, organizers also are offering virtual events at discounted rates.
