35 upcoming half marathons found · 4 with finish-time stats
Las Vegas running is a city of two personalities: the Strip sidewalks, where you log miles past casino marquees and pedestrian bridges in the predawn dark before the heat arrives, and the desert escapes just outside the valley - Red Rock Canyon, Mt. Charleston, Bootleg Canyon - where the terrain turns rugged and the temperature becomes the whole conversation.
Heat is not a footnote here; it shapes everything about when and how people race. Locals shift long efforts to after dark or head for elevation when summer bites. That culture shows up in the race calendar too, with events scattered across the year and a handful leaning into the city's after-hours identity.

Common Questions About Running a Half Marathon in Las Vegas
When is the best time of year to race a half marathon in Las Vegas?
Fall, from September through November, is the busiest stretch with 14 races. Winter, December through February, comes second with 12. Summer has the fewest - 6 races - and given how Las Vegas locals talk about the heat, that scarcity makes sense. January is the single busiest month, with 5 races.
Will I get a shirt at a Las Vegas half marathon?
31 of the 32 races say they give a shirt. The one race that hasn't said anything about giveaways didn't say there's no shirt - it just hasn't said. No races here mention a finisher medal, though most races publish nothing about giveaways beyond the shirt.
Are Las Vegas half marathons good for first-timers?
Most races here pair the half marathon with a 5K, 10K, and a 1-mile option on the same day, so you can step up from a shorter distance as your training progresses and race alongside people doing the same event weekend. The flat urban terrain - common along the Strip corridor - also suits a first long-distance effort better than hilly desert courses.
What is a typical finish time for a Las Vegas half marathon?
None of the 32 half marathons on this calendar have published finish-time results, so there is no measured figure available. Without that data, there is no honest answer to what a typical finisher runs here - and any number you see elsewhere is a guess, not a measurement from these specific races.
