What’s one marathon when you can run 366? In one year? This is exactly what Denmark’s Annette Fredskov did.

After running two marathons on Sunday, the 41-year-old wife and mother completed her 365th and 366th 26.2-mile trips in one calendar year. The journey began July 15, 2012.

Fredskov said she began running three years ago after being diagnosed with multiple sclerosis. She wanted to do something in spite of the disease, so she laced up a pair of shoes and started running.

“Three years ago, I was diagnosed with multiple sclerosis and today I have — without any medication — no problems or symptoms of MS,” Fredskov wrote on her website. “I believe that running marathons has played a large role in the fact that I am healthy today.”

Fredskov said she was skeptical of running a marathon at first, but she’s since grown to appreciate them. And that’s a good thing, since she just spent year running one every day.

“I thought the same thing most people think: ‘Running a marathon isn’t healthy. A marathon is damaging to the body and it takes a long time to recover,’” she wrote. “I have now changed my mind. Marathons are the best things that have happened for my body and soul.”

Most of her marathons took around five hours and were run around her hometown of Naestved, Denmark.

In case you’re wondering, 366 marathons equates to 9,589.2 miles.

Also, Annette is on Endomondo. I only know this because whenever she’s on a challenge she is a nightmare to beat. :P
