A man broke the world record for completing a feat attempted by only five people. He is the second able to say he did it.
Croix Sather ran 146 miles through Death Valley, and did it all while pushing a 250 lb. cart filled with supplies for the journey.
Sather wasn't allowed to have any support or assistance of any kind during the run.
The journey started at Badwater Basin and ended at the top of Mt. Whitney, the highest point on the contiguous U.S. He faced temperatures as high as 129 degrees and as low as subzero.
He broke celebrity runner Marshall Ulrich's world record by 4 hours and 51 minutes, for a total time of 72 hours and 55 minutes.
Sather is also the author of "Dream Big Act Big."
