Duff Dog Backyard Ultra
Duff Dog Backyard Ultra is held at Blue Mounds State Park near Luverne, MN, and uses the park’s established trail system. The loop course is primarily grass with a small amount of gravel and a short paved section. The layout is described as runner friendly and is suitable for repeated laps.
The event follows the Backyard Ultra format with a mandated loop length of 4 miles 880 feet (metric equivalent 6.7056 kilometers). Each loop must be completed within an hour to be counted. Loops start precisely one hour after the previous start, with warnings given three, two, and one minute before each start; all competitors must start at the bell. A measured starting corral is provided and remains the same size throughout the event; participants must be in the corral at the bell.
On-course rules specify that, except for restrooms, competitors may not leave the course until a loop is finished. No non-competitors are allowed on the course and personal aid is not permitted during a loop although common aid stations are allowed. Artificial aids, including trekking poles, are prohibited and slower runners must allow passes. Timing of loops is optional. The winner is the last person to complete a loop; all others are recorded as DNF with distance covered reported. The race is open ended.
