Woodmen Hills Monster Mash 5k and Beer Run

Woodmen Hills Monster Mash 5k and Beer Run takes place in Peyton, Colorado, on October 31, 2026. One distance is on the schedule, a 5K over 3.1 miles, and it starts at 10:00 a.m. That is a late enough gun to eat a normal breakfast, travel in on the morning and warm up properly instead of stumbling to the line in the dark.

A 5K on the last day of October makes a natural end point for a short, focused block. Three or four weeks of intervals at 5K effort, whether mile repeats or shorter reps with jogged recoveries, are enough to put you in personal-best shape, and the distance leaves you recovered within a couple of days. If you plan to run in costume, do at least one training run in whatever you intend to wear: a mask or a cape that seems harmless standing still gets old well before the second mile.
