The Original Las Vegas Half Marathon
Race Day Weather
Comfortable temps, big temp swing
Starting at 61°F, heat will be a factor from the gun — go out conservative and stay on top of hydration. Temps will climb significantly to 82°F by later miles, so expect fading conditions as the race progresses. Light winds shouldn't be a major factor for pacing.

Race Info
The Half Marathon covers 13.1 miles on a single loop of the out-and-back course, starting and finishing at the M Resort in Henderson, Nevada. Most of the route follows a paved bike path with views of the desert and the Las Vegas Valley. The terrain is mostly flat with a few gentle rolling hills, and the full marathon runs the same course twice.
