The Cedar City Half is a perfect high-altitude trainer for those preparing for full marathons, including the Saint George Marathon which is held only a few weeks later. This 13.1-mile closed-canyon course is one of the nation's fastest. Runners descend from 8,408 feet in elevation (Lat-Long: 37.594145 N, -112.912180 W) to 5,600 feet at the finish line.
