Butterfield Blitz Backyard

Event Overview

The Butterfield Blitz Backyard is a timed trail race with a unique "Blitz" format. Runners complete a 4.167-mile loop every hour. There are three event durations: a 4-hour, 8-hour, and 12-hour Blitz. Placement is determined first by the total number of loops completed, and then by the cumulative time for all loops.

Course Details

The race takes place at Butterfield Trailhead Regional Park in Herriman, Utah, within the Butterfield trail system. The loop is mostly trail (99%) with a small section of fire road (1%). The course involves a gradual climb over the first two miles, followed by a downhill return. Each loop has approximately 512 feet of elevation gain.

• 4-Hour Blitz: Approximately 16.7 miles and 2,048 ft of elevation gain.
• 8-Hour Blitz: Approximately 33.3 miles and 4,096 ft of elevation gain.
• 12-Hour Blitz: Approximately 50 miles and 6,144 ft of elevation gain.

The course will be marked with pink flags, cones, and signs.

The race offers free parking. Packet pickup is available the day before at a local running store, or on race day starting at 5:30 AM. All participants who complete at least one loop receive a finisher's medal. Runners who complete 12 loops (50 miles) also receive a custom leather patch beanie.
