Welcome to the home of the annual Herriman Black Ridge Triathlon. The Black Ridge Reservoir is a water basin in the foothills of southwest Salt Lake City just above Herriman and Riverton Cities. It has a beautiful view of the Salt Lake valley and a sandy beach from which athletes begin the race. This venue is perfect for a fast and fun sprint distance course. There are two transition areas, with T1 at the reservoir and T2 at nearby Butterfield Park. Athletes will swim 500 yds in the reservoir then ride a 14 mile clockwise loop down around Herriman City and into Butterfield Park to begin their 5k run loop along the footpaths and return to Butterfield Park for the finish.
