Hoofin' It Through the Hollows 5K

Hoofin' It Through the Hollows 5K takes place on October 24, 2026 in Centennial, Colorado, with the 5K starting at 5:30 p.m. It is a single-distance late-afternoon race, a rarer format than the morning norm and a convenient one if your Saturday is already spoken for. Centennial sits in the Denver metro area, which means the race is run at altitude.

Altitude is the thing to plan for if you are traveling in: expect to run slower than your sea-level 5K time and pace the race by effort rather than by watch. Locals will not notice it at all. Either way, the 5K rewards short, sharp preparation — three or four weeks of intervals layered on top of easy running — far more than it rewards piling up mileage.
