2027 Death Valley Borax Marathon, Half Marathon, & 10K
About the race
The 2027 Death Valley Borax Marathon, Half Marathon, and 10K runs on the Westside Road in the heart of the Badwater Basin.
The NPS has permitted the event to run on the northern end of the road. The half marathon and 10K are a single out and back, and the marathon does this route twice.
The turnaround point is within a few miles of the lowest point in North America and in the shadow of Telescope Peak. The run starts and finishes at essentially sea level elevation.
The event is limited to 250 total participants due to National Park Service rules and sells out months in advance.

City insight: Death Valley
Death Valley is a desert valley in Eastern California, United States, in the northern Mojave Desert, bordering the Great Basin Desert. The World Meteorological Organization lists it as the site of the hottest surface temperature recorded on Earth, a 134 °F reading from Furnace Creek in 1913 that some modern experts dispute. The desert climate is extremely hot in summer and mild in winter, so winter and early spring are the only practical seasons to race.
