Harriette Thompson, a 92 year 65 days old cancer survivor, on 31 May 2015 became the oldest woman to finish a marathon.

She achieved this fete at San Diego’s Rock 'n' Roll Marathon of 26.2 miles (42.2 kilometers) by completing the race in 7 hours, 24 minutes, 36 seconds. This was her 16th Rock 'n' Roll Marathon and by far, the hardest.

With this, Harriette Thompson of Charlotte, North Carolina got her name inscribed into the record books. The previous record holder was Gladys Burrill. She made the record at the age of 92 years and 19 days at the 2010 Honolulu Marathon.

According to Runner's World, Thompson has been running the San Diego marathon for 16 years and has raised more than 100000 dollar for cancer research in that time.
