Runners make their way through some of the most pristine and unspoiled regions of the Mojave Desert just west of Las Vegas at the Twilight Red Rock Half Marathon, which is organized by the locally based race management company Calico Racing. In contrast to the spring race, the Twilight Red Rock races start in the early evening — parts of the course are not lighted, organizers note, so runners will be required to bring headlamps or a hand-held flashlight with them when they’re out on the course.
Note: The course map above provides the approximate route for the race. Though every effort has been made to ensure its accuracy, changes are sometimes made to race routes due to weather conditions, road closures or other circumstances that can require a course to be changed.
