Aid Stations, Maps and Data

Below are course maps, elevation profiles, driving directions to the race and crew directions. Please be sure to review and print all items that you think you might need as we do not provide hard copies of these maps.

General Information About the Area and the Race:
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 Campround 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.

Crew Access to Aid Stations:
The Minimum Maintenance road leading to Aid Station 1/4 (Bridge) and Aid Station 2/3 (Sand Coulee) is narrow and in poor condition and as a result we will only be allowing 100 milers crews access to these aid stations by vehicle. If 50 mile or 17 mile runners crews are found driving to the aid stations – their runner will disqualified. For 50 or 17 mile crews who wish to meet their runner at these aid stations they may hike to meet you – we will mark some shortcuts (for crew members only – not runners) who wish to make this hike. Crew, family and spectators need to be sure to dress appropriately for hiking on sloppy trails, have a headlamp or flashlight and be sure to give the right of way to the runners when they are on the trail. Crew should be sure to study and print the course map below. We thank you for your understanding, this decision was made for the safety of race crew, family members and friends of the runners and to save your vehicles and the road from damage.

Crew and Volunteer Directions to Aid Stations:
The maps below are directions from the West Assembly area (Start-Finish / Aid Station 5) for crew and volunteers to visit the other aid stations during the race.  Please drive slowly on the gravel roads and use extreme caution.  Park only in areas indicated on the maps – thank you. You can download the maps below in .PDF format to save or print by clicking on them.

Start / Finish Area Layout: Adjacent is a link to a Google Map showing the Zumbro Bottoms West Assembly Area / Horse Campground which is the start / finish area, race headquarters and camping area for the Zumbro Endurance Run.

Driving Directions:
There is no known / assigned / reliable physical address for the Zumbro Endurance Run race start at the Zumbro Bottoms Management Unit – in our experience using THIS GOOGLE MAPS LINK will get you to the race start without issue but since the race takes place in a fairly remote area (with limited cell coverage once you are in the Zumbro River Valley), you should have a backup plan.  Below you will find written directions from the Twin Cities / Minneapolis – St. Paul area of Minnesota, we suggest that you print these directions and bring them with you.

Written Driving Directions to Race Start:
• From the Twin Cities take Hwy 52 South to Zumbrota
• Take the 60 EAST (NOT West) exit toward Zumbro Falls and Wabasha
• After stop sign in Zumbro Falls go another 12 miles on 60 to Cty Hwy 4
• Turn right on 4, go about 3.6 miles to Theilman
• Turn left (East) on Cty RD 86, go about 3 MI, keeping right at any intersections

Alternate Route (and very scenic):
It is also possible to come from the Twin Cities down Highway 61 through Hastings, Red Wing & Lake City

• After going through Lake City turn right on Cty Hwy 4 and go South
• At stop sign for Hwy 60 (about 6.5 miles) continue straight on 4, go about 3.6 miles to Theilman
• Turn left (East) on Cty RD 86, go about 3 miles, keeping right at all intersections

About ESTRS:
Remember when you were young and the summer days were hot, relaxing and seemingly endless?  Well, as adults we still get that but usually only on weekends and holidays… until now.  The Endless Summer Trail Run Series is the brain-child of two passionate Minnesota trail-running main-stays – Rocksteady Running and Twin Cities Running Company.  The series was created to provide low-key, low-pressure trail running / racing opportunities for people of all ages, abilities and levels of experience. Whether you are a seasoned trail or road racer, first time trail-racer, need a tune-up for your next race, need to get in some speed-work or just want to have some pizza, pop and beer with us at the finish – running one or all of the races in the series is for you.  The Endless Summer Trail Run Series has garnered a strong local following and has gotten significant national media coverage as one of the best organized and most well attended trail running series in the country!
