3The Palo Duro Canyon State Park holds one of the most scenic and gorgeous trails that a runner could ask for. The Givens, Spicer & Lowry Trail and many other trails in the area serve as a hotspot for running enthusiasts anxious to see deep and stunning canyons, creeks, and outstretched meadows painted with the colors of the southern desert. The race includes 20k, 50k, and 50-mile courses, and is especially attractive to those who enjoy long-distance running. The race has been held since 1980 and is one of the most popular (if not the most naturally stunning) running trails in the southwest.
