Danish woman runs 366 marathons in 365 days

A Danish woman who said she was diagnosed with multiple sclerosis three years ago just completed a marathon of marathons, running her 366th in 365 days.

Annette Fredskov, 41, of Naestved, ran 26.2 miles every day and wrapped up her feat on July 14 by running a double marathon -- 52.4 miles -- in 10 hours and 44 minutes, CPHPost.DK reported.

After being diagnosed with MS, Fredskov decided to run to try to overcome the disease.

"Three years ago, I was diagnosed with multiple sclerosis and today I have -- without any medication -- no problems or symptoms of MS. I believe that running marathons has played a large role in the fact that I am healthy today," Fredskov wrote on her website. "Two years ago, 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.' I have now changed my mind. Marathons are the best things that have happened for my body and soul."

Dozens of supporters ran with Fredskov as she completed mile 9,589.2, CPHPost.DK reported.

Fredskov began her challenge on July 15, 2012.  Most of the marathons took Fredskov about five hours, and took place in her Naestved, her hometown, which is an hour south of Copenhagen.
