Harriette Thompson, 91 y-o and recovering from cancer breaks Marathon Record....She also became the second-oldest woman to complete a marathon in U.S. history raising more than $90,000 for the Leukemia & Lymphoma Society.

For Harriette Thompson, 15th time's the charm.

That's how many times the 91-year-old has run the Rock 'n' Roll San Diego Marathon. This past Sunday, the North Carolinian not only conquered the 26.2-mile course, she broke a few records and fought back against cancer, too.

Thompson now holds a new record for fastest marathon run in American history within the 90-94-year-old age group, with an astounding time of 7 hours, 7 minutes and 42 seconds. She also became the oldest woman to complete the San Diego race, and the second oldest marathon competitor in U.S. history, according to NBC 7 San Diego News.

"I try to run around the block, and I do a few 5Ks," she told the outlet of her preparation for the event. "I think the most I’ve done this year is an 8K, so it’s sort of a lot to ask to jump from that to 26."

While breaking records is great, what Thompson achieved beyond pounding the pavement is what's truly remarkable -- raising more than $90,000 for the Leukemia & Lymphoma Society. It's a cause that's near and dear to her heart, as she'd just undergone radiation treatment on her own legs -- incredibly, just one month prior to completing the Rock ‘n’ Roll San Diego Marathon, the Charlotte Observer reported. more
