Harriette Thompson, a 92-year-old cancer survivor wants to be named as the oldest woman to finish a marathon.

Thompson, from Charlotte, N.C., will compete in the Rock 'n' Roll Marathon in San Diego on Sunday which will be her 16th time running in the race.

"I have no idea if I'm going to be able to do it, but I'm going to try," Thompson said, the Associated Press reported.

 She finished the race in 7 hours, 7 minutes and 42 seconds last year, beating the previous record set bya woman 90 or older, according to Today Online

Thompson survived cancer twice and had to deal with several issues while training for this year's race, such as the loss of her husband and a staph infection in her legs. 

As a classically trained pianist, Thompson says she mentally plays old piano pieces to help her finish the 26.2-mile race.

"I just don't think of myself being that unusual," she said. "I have a lot of people saying what an inspiration I am. That's nice to hear, good for something at this age."

Thompson will be 92 years and 65 days old on Sunday, according to Yahoo! NewsThe current record for the oldest woman to complete a marathon was set by Gladys Burrill, who was 92 years and 19 days old when she ran in the 2010 Honolulu Marathon.
