Unassisted solo crossings In 1994, Scott Weber became the first runner to cross from the summit of Mount Whitney to Badwater course solo without a crew. He did so by pushing a 'baby-jogger' cart with his supplies going oasis to oasis ( apart). Weber then continued on to complete 2 additional crossing with minimal support until being crewed full-time for the final of this 438+ mile journey. Unassisted "self-contained" solo crossings In July 1999, Marshall Ulrich became the first runner to complete the Badwater-to-Summit course without a crew or resupply, denying himself the use of artificial shade or outside aid of any kind. Starting with of gear and water loaded in a modified baby jogger, he pushed and pulled the cart to the Whitney trail head, then continued on to the summit with a pack. He reached Whitney's summit in seventy seven hours and forty six minutes. In July 2004, Jeff Sauter became the second person to attempt a solo self-contained crossing under Marshall Ulrich's rules, and completed the 135 mile course to Whitney Portal in 72 hours, but succumbed to hypothermia on the way to the summit and failed to finish the 146 mile course. Ben "Badwater" Jones, the reference authority and person who documents Badwater crossings, documented the following attempts on his website. http://www.badwaterbenjones.com -> Badwater/Mt.

She pushed and pulled a custom-built 3-wheeled cart filled with water and gear that weighed 240 pounds at the start from Badwater to the Whitney trail head, and then continued the remaining 11 miles to the summit with a pack that she carried from the start. She reached the Mt. Whitney summit in 89 hours and 38 minutes. On July 14, 2016, Dusty Hardman became the second woman to complete Badwater 146 in 80 hours and 57 minutes while pushing a modified baby stroller.
