Backyard Ultra of Northern Utah

The Backyard Ultra of Northern Utah is a technical endurance race held at the Mantua Reservoir on Saturday, May 30, 2026. This event follows the specific "Backyard Ultra" format, where participants must complete a 4.167-mile loop every hour on the hour. The race continues until only one runner remains to complete a "Yard" alone, making it a unique test of mental and physical stamina where there is no predetermined finish line.

Course and Terrain Logistics:

• -- Surface Profile: The trail is described as flat and fast, consisting primarily of firm dirt with some gravel sections. With only 20 feet of elevation gain per loop, it is conducive to long-distance efforts and setting personal records.
• -- Footwear Recommendation: Due to the even surface, many participants choose to wear cushioned road running shoes rather than traditional aggressive trail shoes.
• -- Scenic Environment: The loop circumnavigates the Mantua Reservoir. During the late May timeframe, the area is known for its famous poppy fields, green farmland, and mountain views.
• -- Night Running: Because the race can last for multiple days, the course is designed as a continuous loop (not an out-and-back) to provide a seamless experience during nighttime hours with headlamps.

Format and Competitor Information:

• -- Accessible Ultra: The format is marketed as an ideal entry point for new ultra-runners, as they can test their limits without the pressure of a mandatory DNF (Did Not Finish) for not reaching a specific distant milestone.
• -- Advanced Goals: For experienced athletes, the event provides the platform to reach the 100-mile mark (often rewarded with a belt buckle) or push into the 200+ mile elite range.
• -- Climate: Ideal spring temperatures are expected in Northern Utah for the late May dates, providing optimal conditions for high-mileage output.
• -- Registration Management: Sign-ups are managed through UltraSignup, where participants can also track entrants and view directions to the staging area.

The Backyard Ultra of Northern Utah 2026 offers a high-purity endurance experience, balancing the beauty of the Mantua poppy season with the grueling, repetitive nature of last-man-standing racing.
