About the Lake Chabot Trail Run
Lake Chabot Trail Run covers serious ground around a regional park, and the terrain is genuinely mixed. The shorter distances lean heavily on asphalt and dirt road, while the longer ones push deeper into the hills with real elevation gain. Nothing here is flat. The routes get harder as the distances grow, and the longest options are full mountain efforts.
Check-in opens race morning at the park marina, so there is no separate pickup day to plan around. Arrive early, the organizers ask for a cushion before your wave goes off. Parking costs a small fee per vehicle, and exact change makes entry faster. Runners in the longer events can leave a drop bag at the start and finish area.

Going by the 2025 results, this is a small, friendly field, and the spread of finish times is wide, so this is a mostly recreational race rather than one for club runners.

The Lake Chabot Trail Run has been held every year since at least 2021. That is as far back as RunSignup's records for this race go, so it may well be older.
How we calculate these stats: RunSesh calculates these figures from the most recent published results of past editions, sourced from RunSignup. We show aggregates only: field size, winning and median times, and the cutoff. We never publish individual finisher tables. Last updated Oct 25, 2026.
