About the All-Out Kooky-Spooky
The course follows Ralston Creek Trail along the edge of Blunn Reservoir, mostly on concrete with short stretches of asphalt and a brief unpaved section worth knowing about if you use a wheelchair or stroller. The route is an out-and-back, so you get a second look at the same scenery returning. The foothills sit in the background the whole way.
Packet pickup is available the afternoon before at a location announced closer to the date, and again race morning before each distance goes off. The race leans into the Halloween theme, with a costume contest running in the hours before the last wave starts. Post-race, the engraving tent is worth a stop.

The All-Out Kooky-Spooky has been held every year since at least 2012. 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.
