Backyard Ultra of Northern Utah
The Backyard Ultra of Northern Utah is scheduled for May 30, 2026, and uses the Backyard Ultra format on a measured loop at Mantua Reservoir, Utah. The course is exactly 4.1 miles per loop and is laid out as a loop only, with no out-and-back sections.
The trail surface is firm dirt with some gravel and is described as flat, with about 20 feet of elevation gain per loop. Springtime scenery includes Mantua Poppy Fields, green farmland, mountain hillsides, and local wildlife around the reservoir. Nighttime running on the loop often involves headlamps around the lake.
In the Backyard Ultra format, runners complete repeated loops of the same distance and there is no fixed total distance to cover. Many participants choose cushioned road shoes for the surface and profile of the trail. The combination of a measured loop, low per-loop elevation, and firm trail surface defines the event course and format. Visit the organization's website for the most recent information.
