Harriette Thompson, the irrepressible nonagenarian who in 2015 became the oldest woman to finish a marathon, died Monday in Charlotte, North Carolina. She was 94. A two-time cancer survivor, Thompson was a regular at the San Diego Rock 'n' Roll Marathon, running with Team in Training for the Leukemia and Lymphoma Society. She started running the marathon in San Diego in 1999, and ran the race every year through 2015, except for 2003, when she was undergoing treatment for cancer. She raised more than $115,000 for cancer research through her efforts. In 2015, at 92 years and 93 days, she finished the marathon in 7:24:36, breaking the record for oldest woman to run a marathon previously held by Gladys Burrill, who at 92 years and 19 days ran 9:53 at the Honolulu Marathon in 2010. Thompson was slowed by many admirers who sought pictures with her during races. Since I'm so old, everybody wants to have their picture taken with me," Thompson told Runner's World in 2015. "Brenny says, 'Don't stop her, just take a selfie,' rather than stop and take pictures all the time, because I'd never get to the end. But it's funny, all you need to do is get to be 90-something and you get lots of attention." In June, at age 94, Thompson completed the half marathon at San Diego in 3:42:56, also a record for oldest woman to complete the 13.1-mile distance. "I never thought of myself as an athlete, but I feel like running is just something we all do naturally," Thompson said.
