About the All-Out Runapalooza
The course runs along the Ralston Creek Trail, a paved path that follows the creek through open spaces and past golf course communities. The shorter distances head out and turn back for a downhill finish. The half marathon breaks away from the trail to take on the Blunn Reservoir loop, where the terrain gets harder and the views open up toward the mountains.
Early packet pickup is at a local running store the evening before the race. Race-morning pickup is also available, but each distance has a firm cutoff, so arriving with time to spare matters. The post-race setup moves to Colorado Tap House.

Finish-Time Stats
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 All-Out Runapalooza has been held every year since at least 2013. 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.
