Step into history at the Dick Collins Firetrails, returning on September 26, 2026, to the scenic East Bay hills of Castro Valley, CA. This iconic event, hosted at Lake Chabot Marina, offers a challenging yet rewarding experience with distances including a 50-mile ultra and a full Marathon. Runners also have the option of tackling the Bay Ridge 100k. You'll trace routes through a series of stunning East Bay Regional Parks, including sections of Lake Chabot, Skyline Park, Sibley, and Tilden Regional Parks, featuring panoramic views of Mt. Diablo and the San Francisco Bay.

The course is renowned for its diverse terrain, presenting a true test of trail prowess with roughly 7,800 feet of elevation gain and loss for the 50-mile race. Expect a mix of wide, flat fire roads that invite speed, interspersed with steep, narrow climbs over roots and rocks, winding through ancient redwoods, lush ferns, and sun-baked golden meadows. Typical race day conditions in late September offer mild temperatures, with highs around 77F and lows near 57F, and a minimal 2% chance of precipitation, creating ideal running weather.

The Dick Collins Firetrails carries a deep legacy, honoring ultrarunning pioneer Dick Collins and having been directed for many years by legendary course-record holder Ann Trason. It's celebrated for its "blue-collar," old-school atmosphere, offering well-stocked and friendly aid stations, often with themes, and supportive volunteers. Finishers are greeted with post-race amenities like hot food and a festive atmosphere, making it a favorite for both seasoned ultrarunners and those looking to complete their first trail endurance challenge.
