Walks and runs across Death Valley, in California during the hot summer started as early as 1966 when Jean Pierre Marquant (1938-) from Nice, France accomplished a 102-mile loop around the valley that included climbing two of the high mountains. (see episode 62).

This started a Death Valley hiking and running frenzy in the lowest and hottest place in North America. It mostly concentrated on 100+ mile end-to-end journeys across the blazing wilderness. End-to-end records were set, broken, and recorded by the Death Valley Monument rangers. All of these accomplishments were the roots for what eventually would be the Badwater Ultramarathon.  But when did trekking from Badwater (-282 feet) to the top of Mount Whitney (14,505 feet) start?
