Badwater 135

Badwater 135 Ultramarathon, staged in Death Valley, runs from Badwater Basin—the lowest point in North America—to Whitney Portal near Mt. Whitney, California. The 135-mile (217 km) non-stop course climbs three mountain ranges, with about 14,600 ft of total ascent and 6,100 ft of descent.

The brutal heat, remote desert environment, and dramatic elevation changes define the experience, drawing an international, invitational field of up to about 100 athletes. It’s billed as the world’s toughest foot race within a 48-hour limit. Finisher status earns the belt buckle and recognition among ultrarunning’s most storied achievements, supported by dedicated crews. Visit the organization's website for the most recent information.
