Butterfield Blitz Backyard
Butterfield Blitz Backyard is a timed Backyard Ultra held at Butterfield Trailhead Regional Park in Herriman City, near the Kennecott Mine and the Oquirrh Mountains. The event is scheduled for May 15th, 2027 and uses a single loop course of 4.167 miles that runners repeat once each hour.
The event offers three time-limited options: 4 hour, 8 hour, and 12 hour Blitz Backyards. Each loop is timed and placement is determined first by distance completed and then by cumulative time on all completed laps when distances are equal. Live results update with each lap and show individual lap times and cumulative totals.
Basic rules of the Backyard format apply: runners must complete each loop within the hour to receive credit and may not start the next loop early. Crew and support may use the starting area, but runners may not receive aid on the course except at restrooms once a lap has begun. Trekking poles and pacers are not allowed.
All runners who complete at least one loop receive a finisher medal. The finish area is set up as a well stocked base with snacks and hydration; Tailwind will provide an electrolyte drink, freshly baked pumpkin chocolate chip bread will be offered at the end of the 4 hour event, and pizza will be offered at the end of the 8 hour and 12 hour events.
Packet pickup is available on the Friday before the race at Salt Lake Running Company, 8946 S State St, Sandy, UT. The course is marked with pink flags, cones, and signs. Free parking is available in a large grassy area. Each time option is capped at 60 runners to limit trail congestion. Volunteers receive a $70 credit for a future Happy Trails race.
