Aging Fiercely At 91

Harriette Thompson just set a world record for the fastest marathon ever by a woman 90 years or older. She’s 91, and made her mark at the San Diego Rock and Roll Marathon. She also became the second oldest marathon finisher in U.S. history. She logged those 26.2 miles in 7 hours, 7 minutes and 42 seconds, most of it in the baking sun.
