About the Cougar Mountain Trail Run Series (October)
This edition of the series falls close to Halloween, so a costume contest runs alongside the races. Cougar Mountain's trails are rooted in forest, with enough climbing and winding singletrack to make any distance feel earned. The longer options push deep into the park, while the shorter routes still give you genuine trail running rather than a groomed path.
Post-race, Flying Lion Brewery supplies beer, and there is food to recover with. The Cougar Cup team competition is unique to the longer cross-country distance and requires teams to register the morning of the race, so anyone arriving with a crew should plan for that extra step at check-in.

The Cougar Mountain Trail Run Series (October) has been held every year since at least 2018. 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.
