Duff Dog Backyard Ultra - Luverne, MN
The Duff Dog Backyard Ultra is scheduled for October 10, 2026 at Blue Mounds State Park near Luverne, MN. The event uses an established trail system and a loop course that is mostly grass with some gravel and a short paved section.
The course length is 4 miles 880 feet (metric equivalent 6.7056 kilometers). Runners complete the loop repeatedly with each loop required to be finished within one hour. Starts occur on the hour with warnings three, two, and one minute before each start, and all competitors must be in the starting corral at the bell. Competitors may not leave the course during a loop except to use restrooms. Common aid stations are allowed but personal aid while on a loop is not. Artificial aids including trekking poles are not permitted.
The runner support area offers shade and a shelter building. Camping is available nearby just off the course for family and friends. Timing of loops is optional. The winner is determined as the last person to complete a loop; if no runner completes one more loop than anyone else, there is no winner. The event is open ended, continuing until a single runner completes an additional loop beyond all others. Visit the organization's website for the most recent information.
