Death Valley Marathon, Half Marathon & 10K

Death Valley Marathon, Half Marathon & 10K is held in Death Valley, California, on December 5, 2026. Three distances are on offer, a marathon (26.2 miles), a half marathon (13.1 miles) and a 10K, organized by Envirosports. Start times and elevation gain are not listed.

All three are road events inside Death Valley National Park, which makes this a destination race rather than a course you travel to for a fast time. Give the marathon a full 16- to 18-week build with a weekly long run stretching toward 20 miles; the half asks for roughly 12 weeks and a long run near 11 miles. The 10K is the lighter pick if you would rather not give up the rest of the trip to recovery, and it still gives you an honest hard effort.
