More About the Area:
The Zumbro Endurance Run 100MI, 50MI and 17MI trail races take place within the Zumbro River Bottoms Management Unit in Southeastern Minnesota’s Bluff Country – just outside of the tiny village of Theilman, MN approximately 1:45 from Minneapolis – St.Paul, MN.  The races start and finish at the West Assembly / Horse Campground Area.  Generally speaking the Zumbro River Bottoms Management Unit lies within a portion of the Richard J. Dorer Memorial Hardwood Forest – an expansive 1.7 million acre tract of Minnesota hardwood forest on the Northern edge of the Driftless Region which is mainly characterized by its tall bluffs and deeply carved river valleys. This “bluff country” is rugged, hauntingly beautiful and provides the perfect venue for 100, 50 or 17 miles of trail running.
