About the Redwood (Summer) Trail Run
The courses here run through the hills above Oakland on a mix of wide dirt roads and narrower single track, with very little pavement. The shorter distances stay mellower underfoot, while the longer options pile on serious elevation, gaining more and more the further out you go. Expect rolling to steep grades depending on which distance you choose.
Everything happens at the Chabot Space & Science Center, where check-in opens race morning. Parking is free on site. Runners going long can bring a drop bag with non-valuables to stash at the start and finish area, which is worth planning around.

The Redwood (Summer) 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 Jul 27, 2026.
