Course

The marathon is the half marathon's pink-flagged loop run twice, about 60 percent dirt road with the rest split between asphalt and singletrack. Runners must reach 13 miles within 3 hours 45 minutes, and the overall limit is 8.5 hours.

Race-day weather

Early November in the East Bay hills is usually mild, though early-season rain can leave the dirt roads muddy.

About the race

The fall Lake Chabot trail day offers a 5K up to a 50K from the Marina, and the 2026 edition sold out. Each finisher gets a custom medal, and the overall top three earn race credits.
