Jordan River Blitz Backyard - South Jordan, UT

The Jordan River Blitz Backyard is a backyard ultra held at East River Front Park in South Jordan, Utah. The event uses a 4.167 mile loop on a 100% paved trail with about +45 ft elevation gain per loop. The loop connects directly to the Jordan River Trail and the start/finish area includes grass, shade, and a pavilion.

The event uses a timed "blitz" format where each loop is timed and placement is determined first by distance completed and then by cumulative time on completed loops. Live results display individual lap times and cumulative totals. Course navigation is provided with pink flags, cones, and signs.

Awards and services include finishers medals for anyone completing at least one loop, a custom leather patch beanie for completing 12 loops (50 miles), locally made medals, a running shirt, and food at the finish area including bread and pizza at designated conclusions. Free photos are taken on course and at the finish with bib recognition for downloads. The park offers plentiful free parking, grassy setup areas, a playground, pickleball courts, and shade.

  • 12 Hours: 50 miles, +540 ft elevation

Key race rules include remaining in the starting corral at loop start, completing each loop within the hour to receive credit, no artificial aid or pacers on course, and allowing faster runners to pass. Visit the organization's website for the most recent information.
