91-Year Old Woman Breaks Marathon Record

Harriette Thompson, 91, just completed a full marathon in San Diego. When she crossed the finish line after 7 hours, 7 minutes, and 42 seconds, she broke a record for the 90-94 age group. That's a pace of about 3.7 MPH. She smashed  the previous record, which was held by a 90-year old who completed the run in 8 hours, 53 minutes, and 8 seconds.
What's even more amazing is that Thompson did all of this after just completing cancer treatments. She still has radiation burns on her legs. She braved the 80°F heat anyway and completed her fifteenth marathon. And she's not done yet:

“If I’m still here next year, I think I’ll probably be able to train better and be in better shape,” Thompson said. “If I’m able, I’ll try again.”
