About the race
Butterfield Blitz Backyard is a timed Backyard Ultra held at Butterfield Trailhead Regional Park in Herriman City, located near the Kennecott Mine and the Oquirrh Mountains. The event uses a 4.167 mile loop that runners complete once each hour for a chosen duration. The course is marked with pink flags, cones, and signs, and the finish area provides space for tents, chairs, and a large event parking area. Event distances and formats: - 4 Hour Blitz - hourly 4.167 mile loop format - 8 Hour Blitz - hourly 4.167 mile loop format - 12 Hour Blitz - hourly 4.167 mile loop format This is the Blitz variation of a Backyard Ultra: every loop is timed, and placement is decided first by distance completed and then by cumulative time on all completed laps.
Live results display each runner's individual lap time and cumulative total. Runners who complete at least one loop receive a finisher medal. Runners who complete 12 loops receive a leather patch beanie recognizing the 50 mile accomplishment.
The finish area is stocked with snacks, Tailwind electrolyte drink, locally made finisher medals, shirts, and post‑race food options. Free, watermark free photos are provided and hosted with bib recognition. Each race format is capped at 60 runners to limit trail congestion.
