Dear Friends,

The 2019 Zumbro Endurance Run has been canceled. This cancellation includes the 100, 50 and 17 mile races.

Throughout the forecasting of this storm, the National Weather Service communicated that there were significant unknowns as to the exact track of the storm, the amount of precipitation in any given location, and the distribution of that precipitation (rain vs. snow).

We indicated to runners and volunteers in previous correspondence that we were holding out hope that we could have the race. We indicated that a cancellation or modification may come at anytime.

In order to have any chance of holding the race, we needed the initial round of precipitation to fall as rain versus snow. Today we received heavy, wet, accumulating snow that has already created dangerous conditions on local roads and within the Zumbro Bottoms Management Unit. While we were able to get some equipment in, in advance, and did mark the entire trail, the conditions at the race location today have already made it impossible to safely mobilize the balance of our trucks, trailers, vehicles and ATVs to the race site. Given the current conditions and what is forecast, deploying the equipment and setting up the aid stations tomorrow, or in the coming days, is literally not possible.

With the conditions already too bad to set up for, or hold the race and with more snow, sleet, freezing rain, rain and dangerous winds forecast from now through Friday night – it would be a fool’s errand to blindly march forward, simply hoping that things might not be as bad as forecast or may somehow miraculously get better. Putting our runners, their pacers, crews, families and volunteers at risk (on the roads or on the trails) on the basis of wishful thinking is something that I am unwilling to do.

You put your heart and soul into your running, training, racing and most importantly, our trail community. Cheri and I do too – we eat, sleep and breathe Zumbro during the months leading up to it. We are all beyond disappointed. That said, we know that the disappointment we feel now would pale in comparison to how we would feel if we attempted to hold the race and someone got seriously hurt, or worse. No race is worth that.

Thank you all for everything that you are. Thank you for your fighting spirit and for what you bring to our community. Thank you for your support and understanding.

Please note that I will be following up with a more comprehensive communication regarding the cancellation of this year’s race in the days to come.

Thank You,

John Storkamp
Race Director

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,

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.
