A lot of folks have been hopping on the Insane Running bandwagon as of late. Tough Mudder, Warrior Dash, Muddy Buddy come to mind and there are many others. There has been a race in Hell, Michigan that is nearly two decades old that defines Insane Terrain. Dances With Dirt. DWD is the evil brainchild of Running Fit owner Randy Step, and the main difference between his race and the Johnny Come Latelys is that DWD makes you do more running. A lot more. This year's race is September 24th. The 100k 5-person relay has been sold out since last winter, but you can still enter as a solo runner in the 50k or 50 mile ultramarathons.
