About the Colorado 24 Hour Run
The course is a dirt loop at Colorado Youth Outdoors' Swift Ponds Campus, and you run it as many times as you want within your chosen duration. The terrain is flat and entirely unpaved, passing ponds where raptors, cranes, and waterfowl are common company. Solo runners and relay teams share the same loop, drawing a wide range of approaches.
The aid station runs hot food through the full event, with vegetarian, vegan, and gluten-free options alongside the standard fare. Race photos are taken on course, and results update in real time so crew and teammates can follow along. The daylight-to-dark shift is part of the experience, and the clocks stay on race time through the overnight hours.

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 Colorado 24 Hour Run has been held every year since at least 2024. 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.
