Location and Date: June 25-26, 2023, Death Valley, USA.

Goal: To run from Badwater Basin (-86 meters below sea level) through Death Valley to the highest peak in mainland America (Mount Whitney, 4421 meters).
NB: Due to the fact that Mount Whitney was still covered in snow by the end of June, the challenge had to be finished at the base of Mount Whitney at an elevation of 2548 meters. Therefore, the Badwater135 route was completed.

Result: Due to mistakes in preparation and equipment selection, this challenge became one of the hardest and greatest challenge so far. After completing the distance of two marathons, I had to set aside all time goals and focus on reaching the finish. It took me 40 hours, 9 minutes, and 50 seconds.
