The 2013 Zumbro Endurance Run 100MI, 50MI and 26.2MI are in the books!  It should be of no surprise that when you have an early Spring race in Minnesota, eventually you will have one with some snow.  After a decade of snow-free trail-running in the Zumbro Bottoms this same weekend each year, it finally happened and in a big messy way.

Leading up to this years race it was fun to see the difference in individuals reactions to the conditions.  Some folks were filled with anxiety, certain that it was the end of the world – others were cool, calm and collected and laughed as they did their last few training runs the weeks prior, running through snow, ice, water and mud.  Prior to race day while the rest of the Midwest was getting hammered by an extraordinary early Spring storm, we experienced heavy rain, snow, sleet, ice and winds in excess of 40MPH.  The trail changed almost by the hour and when it was time to mark the course it was obvious that there were dry spots that we were marking would be wet come race day as well as wet spots that might dry out a bit – as a result we made very few revions and just had to go with it.  Snow, ice, mud and sloppy, slippery trails greeted 100 mile runners on Friday and things just deteriorated from there.  Many runners succombed to the conditions after long and protracted battles with the course, a good many carried on and got the finish.  Photos can be found HERE – notice all of the smiling faces – the spirit of the trail / ultrarunner is alilve and well!

A full race report will be written and available in an upcoming issue of Ultrarunner Magazine but below are the quick stats and links to initial results – these are preliminary results and are subject to revisions – timing is a science but sometimes mistakes are made, if your name is missing from the results or if your time is not correct, we will have you in the backup, please just bring it to our attention – if you see something please CONTACT US via email, do not use Facebook, final results will be available within a week or so.  We were unable to get a few awards out during the race – the 17 and 50 just had awards for the overall winners (male and female), but the 100 mile had awards for 1st place in each age division – after we confirm final results, we will mail out awards.

We had an incredible time hosting such a fantastic group of runners – we look forward to seeing you all again next year, hopefully under dryer conditions!

Zumbro 2020

Thank you very much for your interest in the 11th Annual Zumbro Endurance Run 100 Mile, 50 Mile & 17 Mile.  The race was successfully held from its inception in 2009 through 2016, but experienced a couple of really tough years the past two.  The 17 mile race was canceled in 2018 and the entire event / all distances were canceled in 2019 - both years cancellations due to historic early Spring blizzards.  The race has historically been held between the first and second weeks in April and unable to be permitted later in the month due to the Spring turkey hunt.  We are still working through details with the Minnesota DNR for the 2020 event and will share more information with you this Fall regarding the 2020 race, including the race date, course / logistics information, and the date that registration will open. Should you have any questions, please feel free to contact me.  Race Director John Storkamp, racedirector@zumbro100.com

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 – while this is certainly not an “easy” trail race it can still be a great choice for your first 100, 50 or 17, that is if you are ready for a good amount of climbing / elevation gain.  This is a laid back, old school, low-key trail race hosted by ultrarunners for ultrarunners.
