Zumbro Volunteer Communication 3 2023

Date: 4/3/23
Subject: Zumbro Volunteer Communication 3 2023

Volunteers / Friends,

[ If for any reason you did not see Volunteer Communication 2, it should be reviewed as well and can be found HERE https://www.zumbroendurancerun.com/zumbro-volunteer-communication-2-2023/ ]

The reason for my email today is to make you aware of the potential for race course changes due to flooding. Please see HERE https://www.zumbroendurancerun.com/zumbro-2023-potential-course-change/

If we have to transition to a modified course utilizing only trails on the East side of the river, we will move Aid Station 2 / Central to the Bridge site HERE https://goo.gl/maps/pUiqMyy9638GNeTg6 (this was the site of an aid station for many years). As of right now it looks like only those volunteers with 4WD would be able to drive into that aid station. Parking for the Bridge aid station is HERE https://goo.gl/maps/6uCSstcoRwn6Hx7v5 — IF the course is unmodified and Aid Station 2 is at Central as planned, only those with 4WD should drive into that aid station. If you are working that aid station and do not have 4WD, report to the Start / Finish area and check in with the HAM Radio Communications team, they will summon one of the people from the aid station that have indicated they were willing to shuttle runners to come get you, one of our logistics / supply folks will run you over, OR they will also likely be staffed well enough, that we can just use you at the start / finish area.

I will let you know by Wednesday night what the plan is. Thank you for your flexibility! Please let me know if you have any questions.

Thank You,

John Storkamp
Race Director

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.
