Badwater Craziness

In 1989, Tom Crawford and Richard Benyo completed the first double crossing (which became known as the "Death Valley 300"), running from Badwater to Mount Whitney's summit and back to Badwater again.

In 1994, Scott Weber completed the first Triple Crossing going from the Mount Whitney Summit to Badwater, then returning from Badwater to the Mount Whitney summit, then going from the Mount Whitney summit back to Badwater in 10 days. The first leg of the Triple was also done solo unassisted with Weber pushing an unmodified 'baby jogger' cart with his supplies from oasis to oasis spaced from 20 to 30 miles (48 km) apart. Weber completed the majority of the triple unassisted and solo being met once or twice a day by Ben on the second leg and for 100 miles (160 km) of the third leg. Faced with the necessity of completing the Triple before August ended, Weber abandoned his cart at mile 390 to be fully crewed by Denise Jones. Completing this Triple and adding the Badwater race from the previous month made Weber the first runner to complete four full crossings of the Badwater-Mount Whitney summit course in a single July–August window. He remains the only runner to have done a multiple crossing with a solo unassisted section of 146 miles (235 km) or greater.

In 2001, Marshall Ulrich was the first runner to complete the "Badwater Quad", consisting of two back-to-back Death Valley 300s for a total of four consecutive Badwater/Whitney transits. He completed the course, a distance in excess of twenty-two marathons, in ten days.

In 2003, Sawyer Manuj became the first Asian-American to complete the Badwater duo.
