A Dallas runner will be the first woman in the US to complete 1000 marathons and will subsequently enter the Guinness Book of World Records which she had already done before in 2013 according to an Indiatimes article from April 3. They say, 

“This woman named Angela Tortorice of Dallas, who has run 999 marathons in her career, entered the Guinness Book of World Records in 2013 after completing 129 marathons in a single year. Incredibly, she has run at least five marathons in every US state. 

“My vacation time is used for marathoning. It’s not used for anything else,” she said.

She will compete in her 1,000th marathon at the Irving Marathon in Texas. If she completes the race, she will become the first woman in the US to reach the milestone number.”

According to her, running marathons meant a lot for her especially since her husband passed away from multiple sclerosis. But of course, awareness isn’t her only reason as she values the experience as well according to a Pennlive article from April 5 which reports, 

“Irving Weekly reports how 54-year-old Angela Tortorice first ran a marathon back in 1997 as a way to raise money and awareness for multiple sclerosis after her husband was diagnosed with the disease. She has since completed a marathon in all 50 states, and has raised $165,000 for the Multiple Sclerosis Society to boot.

“The endorphins make you feel so good,” she says of her experience. “I’ve met so many wonderful people. Runners are so positive. The running community is an extension of my family.”

Tortorice, however, is not finished in setting her record at 1000 as she is already set to run the following week for another marathon. After that, she will have 1001 marathons, breaking the 1000th record in the Guinness Book of World Records.
