Renaissance Athlete

Michael Kasser is a shortish, 155-pound, 43-year-old “Iron Man” who ran the London Marathon last April 18, jetted the Atlantic that night, and ran the Boston Marathon the next day, averaging three hours a race.

He has goat-footed down a snowy Nevada trail in the pre-dawn dark 6,000 feet above sea level to finish the Western States 100-Mile Endurance run. He has also swum in the sea off Hawaii watching dolphins cavort beneath him during an Ironman Triathlon. And in the same Tri he biked more than a hundred miles through a volcanic landscape baked hotter than the sunny side of the moon.
