From the Organizer
Join us on Sunday, January 10, 2027 for a race event unlike any other in Maine. Get out of the cold and head indoors: no ice underfoot, no frigid gusts in your face, and no snow overhead! Who knew running in circles was so much fun? Music, comaraderie, and running! Walkers welcome.
Indoor Insanity 5K is a fundraiser to prevent lung cancer. Your race fees help pay for installation of radon mitigation systems in low-income Maine households.
To minimize injury and "traffic jams", runners pick their preferred heat based on their average personal running speed.
Heat # 1 - for the fastest runners (15-20 minutes 5k) Field will be limited to 30 runners. First come, first served sign ups
Heat #2 - for the intermediate runners (20-27 minute 5k) Field will be limited to 75 runners. First come, first served sign ups
Heat #3 - for runners of any level willing to take on the chaos of Indoor Insanity.
Walkers: we have two dedicated lanes for walkers. Walkers start with Heat #1 Runners
Kids Fun Run, too!
The race is professionally chip-timed for accurate individual lap and finish times.
Race fees are for race only. The deadline to purchase race shirts if you want one is December 22, 2025. We will have limited quantities available for purchase on the day of the event. First-come, first-served.
Please consider fundraising to help us mitigate more homes.
