Halloween Fun 5k

Halloween Fun 5k takes place in Steamboat Springs, Colorado, on October 31, 2026, with the Fun 5K starting at 9:00 a.m. The format is deliberately simple: one distance, a mid-morning start and a Halloween date.

Steamboat Springs sits high in the Rockies, and that altitude is the single biggest factor in how this run will feel. If you are visiting from lower ground, expect your usual pace to cost noticeably more effort and run the first mile by breathing rather than by your watch. Locals can treat it as a hard 3.1 miles at the end of the fall season. Either way, dress for a cold start and a much warmer finish, and get a proper warm-up in before 9:00 a.m.
