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.

The course consists of a mix of rugged single and double track trail with rubble, loose rock and sand along with minimum maintenance gravel roads. The race is primarily concentrated in two large valleys within an expansive hardwood forest. There are four significant, short, steep climbs (approx 300FT) per loop with small hills in-between along with some significant stretches of flat valley floor running.

The weather can be extremely variable for the Zumbro Endurance Run – there have been years of near 100% snow-cover and blizzard like conditions and other years dry with highs in the mid-70’s.  Due to a record setting blizzard and hazardous driving conditions the 2018 edition of the 17 mile race was canceled – the 100 and 50 proceeded “mostly” as normal.  In 2019 the race was completely canceled for the same reason.  You can learn more about this on the blog section of our website HERE http://www.zumbroendurancerun.com/news-and-updates/

Zumbro 2020

The 2020 Zumbro Endurance Run has been scheduled for Friday April 10 and Saturday April 11, 2020.  Registration will open on Friday November 1, 2019.

Before registering for this years race, we are requiring all runners to read the following disclosure and acknowledgement in its entirety https://www.zumbroendurancerun.com/zumbro-2020 -  It will take you about 7 minutes to read. It covers the following key points.  

1.) Zumbro was partially cancelled in 2018 due to an abnormal / early Spring blizzard. 

2.) Zumbro was completely cancelled in 2019 due to an abnormal / early Spring blizzard. 

3.) Zumbro is not immune to a third such weather event. In the event that we must cancel the race for any reason, there will be no refunds and the race(s) will not be rescheduled.  

4.) Those intending to register and run in 2020 should be fully aware of significant course, aid and access changes.  

5.) Zumbro does take place on the Friday and Saturday prior to Easter Sunday in 2020.

Given the weather these past couple of years, we totally understand if you do not want to take the risk of signing up for Zumbro and are certainly not asking you to. There are a lot of other great races that you can sign up for in the Midwest and North later in April and in early May. We are totally fine having a smaller event. Whatever you decide is totally, completely, 100% fine with us.  We wish you the best of luck with whatever you run this coming Spring.  We thank you for your ongoing interest and support.
