The CV50/50 is comprised of two out-and-back segments on the Arizona National Scenic Trail. The course begins by heading 16.9 miles south from La Posta Quemada Ranch at Colossal Cave. 55K runners return to the ranch for a finishing distance of almost 34 miles! The 50-mile racers continue past La Posta Quemada to the northern stretch of the course and cover 8 additional miles. Daytime half-marathoners run south on the Arizona Trail for almost 6 miles, then a short segment of dirt roads and and sandy arroyos before returning to the trail and running north back to the finish line. Nighttime half-marathoners run north on the Arizona Trail for an out-and-back that overlaps with the end of the 50-mile race. The race concludes at La Posta Quemada where food and festivities await.
