This Is GrindFest (with Terry Witkowski)

"What if we just ran until we couldn't anymore?" -Terry Witkowski, circa 2013

So began the world's largest indoor progression run, and the most fun night of distance running in the state of Wisconsin. 

In the past six years, Olympic Trials Qualifiers, NCAA All-Americans & National Champions, professional runners, and everyday runners have joined in the Grind to see how if they could be the one runner left standing. Starting at 6:08 pace and dropping every 3 laps (~1400m), GrindFest takes the progression run from a summer workout to a full-on race with an epic finish.
