Death Valley, United States of America · Sunday 6 December 2026
This race works best for runners who thrive in extreme heat and don't mind a bit of suffering. The December timing helps, but Death Valley is still scorching even in winter, and the elevation changes across the course mean you'll face significant altitude variation as you move between the low points and higher terrain. You need to be comfortable with self-sufficiency, solid pacing discipline, and the mental toughness to keep moving when conditions get harsh. If you've done desert running before and know how to manage heat, nutrition, and hydration over distance, this could be your kind of challenge. Runners seeking a fast, comfortable marathon experience should look elsewhere. The course presents a deceptive profile. While it shows flat to gently rolling terrain, the fact that you'll start at one elevation and potentially climb to 1600 meters above sea level means this isn't the straightforward course the description might suggest. Death Valley's landscape is relentless rather than dramatic, with sparse scenery and long stretches of exposed running. The road surface is stable, which is good for your legs, but there's minimal shade or shelter from the elements. The real difficulty isn't technical or steep but rather the cumulative effect of heat, distance, and the psychological weight of running through an unforgiving environment. Respect the desert or it will humble you, and make sure your support crew and aid station strategy is locked down well before race day.
