Hoover Dam Marathon

The Hoover Dam Marathon is a scenic and historic race held at Lake Mead National Recreation Area near Boulder City, Nevada, about 18 miles from Las Vegas. The event offers marathon, half marathon, 10K, and 5K distances. Runners start at Boulder Beach and traverse the beautifully paved River Mountains Loop Trail and the Historic Railroad Tunnel Trail, which features old railroad tunnels overlooking Lake Mead.

The course includes a notable descent via six switchbacks to the Hoover Dam parking garage, providing stunning views of the dam and the Bypass Bridge. Marathoners complete two loops of the course. The route is a mix of packed dirt and paved asphalt, certified for accuracy and an official qualifier. Visit the organization's website for the most recent information.
