Lake Mead Marathon, Half Marathon, 10K & 5K

Lake Mead Marathon, Half Marathon, 10K & 5K is run at Boulder Beach in the Lake Mead National Recreation Area, Nevada, on January 9, 2027. The marathon (26.2 miles) starts at 8:00 a.m., the half marathon (13.1 miles) at 8:30, the 10K at 8:35 and the 5K at 8:40. Four distances inside a national recreation area, all going off within forty minutes of one another, make for a compact morning.

A January marathon in southern Nevada is a common target for runners who spent the fall building rather than racing. If 26.2 is the goal, a 16-week block with a weekly long run reaching 18 to 20 miles is the standard preparation, and the half at 8:30 is the sensible fallback if that block was interrupted. Whatever you enter, treat a course inside a recreation area as one where you should know what you are carrying between aid stations.
