Duff Dog Backyard Ultra

The Duff Dog Backyard Ultra operates on the classic last-person-standing format, taking place within Blue Mounds State Park just outside Luverne, Minnesota. You will tackle a standard 4.167-mile (6.706-kilometer) loop every hour on the hour until only one participant remains. Set against the backdrop of the park's prairie bluffs and quartzite cliff lines, the route utilizes established park trails. The running surface consists primarily of grass (roughly 95%), mixed with minimal sections of packed gravel and short paved connectors.

While the terrain lacks severe mountain grades, the rolling prairie elevation accumulates steadily over successive hours, totaling approximately 2,500 feet of gain across every 50 miles. Running on grass presents a unique physiological challenge: softer footing reduces joint impact early on, but uneven turf and repetitive stride mechanics demand steady ankle stability. As daylight fades into night laps, managing your pace across natural ground surfaces requires consistent headlamp focus, disciplined pacing, and reliable foot strike mechanics to avoid tripping on subtle undulations.

Luverne is situated in southwestern Minnesota along Interstate 90, making highway travel straightforward. If you are flying in, Sioux Falls Regional Airport (FSD) in South Dakota is the most practical gateway, located approximately 35 miles west. For additional flight options, Minneapolis-Saint Paul International Airport (MSP) is roughly a three-and-a-half-hour drive to the northeast.

For lodging, Luverne offers standard hotel accommodations and local amenities only a few miles south of Blue Mounds State Park. Alternatively, camping is available directly within the state park near the course, providing your crew immediate access to your gear and base camp throughout the event. Base facilities include park shelters and shaded staging areas for between-lap recovery. October in southwestern Minnesota brings crisp autumn conditions, with daytime temperatures often in the 50s or 60s Fahrenheit and overnight lows dipping toward freezing. Prepare layered apparel, wind-resistant outer shells, dry footwear changes, and cold-weather sleeping setups to stay warm during recovery intervals.
