Pete Kostelnick, a running master who set the fastest time for running across America, breaking the previous mark by over 4 days. He averaged 72 miles a day to finish in 42 days, 6 hours, and 30 minutes. He's also finished Badwater 3 times, won it twice, and holds the course record. Needless to say, he's fast, really really fast, and go run for a very long time!
