Butterfield Blitz Backyard

Herriman, United States • 15 May 2027

Butterfield Blitz Backyard is a timed backyard ultra held at Butterfield Trailhead Regional Park in Herriman, UT on May 15, 2027. The event uses a 4.167 mile loop that runners complete once each hour for either 4, 8, or 12 hours. Each loop has about +512 ft elevation gain and is mostly trail with a gradual climb for the first two miles and a downhill return through dense foliage. The Blitz Backyard format records individual lap times and cumulative time.

Placement is based first on distance completed and then on total cumulative time for runners with the same number of laps. Live results update with each completed lap and show individual lap times and cumulative totals. Facilities and services include a well stocked finish area and aid station with snacks and Tailwind electrolyte drink, locally made finisher medals, event shirts, free parking, and course marking with pink flags, cones, and signs. Photos will be taken on course and at the finish by Xotio Media and hosted for download using bib recognition.

Packet pickup is offered at the Sandy Salt Lake Running Store and race day pickup is available. Awards and recognition: all runners who complete at least one loop receive a finisher medal; completing 12 loops earns a leather patch beanie to reflect a 50 mile accomplishment. Each distance is capped to 60 runners to limit single track congestion. Rules emphasize completing each loop within the hour, no artificial aid or pacers, and allowing passes on trail sections.
