Lake Chabot Trail Run

Lake Chabot Trail Run is a multi-distance trail race held at Lake Chabot Regional Park – Marina in Castro Valley, CA. The event offers 8K, Half Marathon, 30K, Marathon, 50K, and a Kids Run, inviting runners of varied backgrounds. The course starts at the Marina and loops around the Lake Chabot reservoir through surrounding hills, with a mix of single-track trails, dirt roads, and asphalt.

Distances are precisely measured with a surveyor’s wheel. Runners navigate using polka-dot flagging and color-coded loops (8K yellow; HM pink; 30K pink+yellow; marathon double pink; 50K marathon + 8K). Fully stocked aid stations every 4–5 miles; cupless policy and drop bags are available.

Great for first-time trail runners. Visit the organization's website for the most recent information.
