The Zumbro Endurance Run hosts two races simultaneously, the Zumbro 100 Mile Endurance Run (starts at 8:00 AM Friday) and the Zumbro Midnight 50 (starts at 12:01 AM Saturday) . Each distance will have its own unique race number (unique color and number series) so runners can be easily identified by race officials, volunteers, spectators and other runners. Runners who register by the deadline will have their name custom printed on their race numbers along with other important information and emergency contact information. We ask that all competitors wear their number on the front of their body on their outer-most layer at all times. Runners will be tracked coming into and out of each aid station. If we cannot see your number, we cannot track you or take your finishing time and if we cannot do that, you will be disqualified and will not earn an official finish.

The Zumbro Endurance Run will be chip timed. Your timing chip will be affixed to the back of your race number. Do not remove your timing chip. Do not bend or fold your timing chip or crumple your race number – this may break your timing chip. Your race number and your timing chip must be pinned on your outer-most layer at all times. Above guidelines must be followed in order ensure that split times and finish times are recorded. This chip is disposable and does not need to be retur

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.

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.
