The Original Las Vegas Marathon
The Original Las Vegas Marathon is a flat marathon in Henderson, USA, held each October. An out-and-back route from the M Resort, mostly along a paved bike path. The organiser calls it mostly flat with a few gentle rolling hills, and it turns back on itself for the full distance. Early mornings in Henderson in October are usually dry and mild, with temperatures of about 12 to 28°C as the sun comes up. On a course as flat as The Original Las Vegas Marathon, even splits are everything; the classic mistake is banking time in the first third.
