Race Overview:

Since 2013, runners from across the Midwest have gathered to celebrate the end of the year with a one-of-a-kind event: an indoor, last-person-standing progression run! 

 

Hosted on the Pettit National Ice Center's 443m track, runners speed up every 3 laps (0.84 miles), until they can't go any faster. With two options for when to start progressing (~6:30 or ~6:10), runners keep running as long as they can hang with the ever increasing pace. When it's down to the final pack, The Bell will be rung and a 3 lap first-to-the-finish race to determine the top places is on. 

 

GrindFest promises to be a blast for all, from runners to spectators, with prizes for the most creative and fastest teams, the athletes who run furthest in an ugly sweater, a prediction contest, and of course, the coveted Mom of the Year award.
