About the Colorado 13er (Half Marathon/10k/5k)
The course starts and finishes at a Home Depot on Dillon Road, which sounds odd until you actually run it. Most of the route is crushed gravel and stays flat, so the footing is easy and the pace tends to feel faster than expected. The Flatirons are visible for much of the run, and the views hold up the whole way around.
Packet pickup the day before is at a running store in Westminster. On race morning, the start and finish area is at the Home Depot lot, but parking is in the Cinebarre and RTD lots nearby, not the store's own lot. After you finish, a local coffee shop on West Cherry Street gives runners a discount on drinks if you bring your bib in.

The Colorado 13er (Half Marathon/10k/5k) has been held every year since at least 2014. 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.
