The Six‑Pack Series isn’t a typical race—it’s a progressive running challenge founded in 2012 in Westminster, expanding soon to Arvada. It’s designed to support novice runners with monthly distance increases: starting at 1 mile, then 3 mile, 5K, 4-mile, and culminating in a 10K by the sixth month.
In November 2026, the Arvada event returns with a 10K “Turkey Trek” and a new Half Turkey option, alongside the traditional 5K “Turkey Trot”, 2K Toddle, and fun holiday-themed challenges five miles of twisty trail climbs, a festive eggnog chug, hay-bale hops, and pie-eating along the way.This isn’t a PR course—it’s a bragging-rights adventure crafted for runners seeking both grit and holiday cheer.
“Are you up for the CHALLENGE?” – race promos cite eggnog and pie checkpoints as earned bragging rights.
This Arvada edition benefits Community Table, a local food bank, and includes festive finishes like a finisher mug, seasonal swag, and hoodies—a hearty holiday reward for participants and volunteers alike.
