Monster Dash 5k - Hutchinson

Monster Dash 5k - Hutchinson is run in Hutchinson, Kansas, on October 31, 2026, with one distance on the schedule: a 5K, 3.1 miles, at 8:00 a.m. What sets it apart is where it goes, roughly 650 feet underground at the Kansas Underground Salt Museum, through lantern-lit tunnels with salt walls and scares placed along the way. Costumes are encouraged and prizes go to the best of them.

The race doubles as the fall fundraiser for the Reno County Historical Society, benefiting the Reno County Museum and Strataca. Underground running is its own thing, since the footing and the light are nothing like a road 5K, so treat this as an experience run rather than a personal-best attempt and keep your effort a notch below what you would hold on pavement. A few weeks of running three or four times a week is all the preparation the distance really asks for.
