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 have historically only allowed 100 milers crews to drive their vehicles to these aid stations. 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.

There have also been a couple of past years where in advance of the race we have also had to restrict driving access for 100 mile crews as well to Aid Station 1/4 as outlined above.  We will notify runners at least two weeks prior to the race so those runners using crews can plan with their crews and adjust drop bags accordingly.

We thank you for your understanding, these decision are made based on variable Spring road conditions and 100 mile field size, 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.
