Hoover Dam Marathon
Boulder City, United States of America · Saturday 6 December 2025
RoadFull Marathon
Held in Boulder City, Nevada, this December marathon takes place in the shadow of one of America's most recognizable engineering achievements. The setting sits at moderate elevation, ranging between 376 and 487 meters above sea level, with the landscape characteristic of the Mojave Desert. Boulder City itself is a smaller community with a genuine, unhurried character, far removed from the glitz of nearby Las Vegas. The proximity to the Hoover Dam and Lake Mead provides dramatic desert backdrop, though runners should be prepared for the climate and terrain of this arid region. The course itself is refreshingly straightforward, offering a flat to gently rolling profile that avoids punishing climbs. This is a road marathon where you won't spend the day fighting elevation, allowing you to focus on pacing and execution rather than managing steep terrain. Runners should expect desert conditions in December, which typically means cool mornings that warm during the day, with the possibility of wind across open stretches. The relatively consistent elevation throughout means there are no major altitude shocks, though the moderate baseline elevation may still require some acclimatization if you're coming from sea level. It's the kind of course that rewards steady effort and clean running.
