Indoor Insanity 5K - Lewiston

Indoor Insanity 5K - Lewiston is an indoor winter run and walk held in Waterville, Maine, on January 10, 2027. The 5K and the walkers' division both start at 8:00 AM, and a kids fun run of about a quarter mile follows at 8:25 AM. The event is traditionally staged in the Lewiston/Waterville area, and its proceeds go toward lung cancer prevention through radon reduction in low-income homes.

Racing a 5K indoors means running laps, and the organizers chip-time them and set wave starts by average pace so the track stays manageable. That changes how you race it: pick your wave honestly, hold a rhythm instead of surging, and expect the turns to cost you a little on every lap compared with a road 5K. It is a practical way to keep a real race on the calendar in the middle of a New England winter, and the short kids run gives younger family members a start line of their own.
