A Danish woman just completed what for most of us is akin to the impossible after finishing her 366th marathon in 365 days. Just for a little perspective (and guilt-tripping, to boot), that equates to over 9,500 miles, which is nearly four times the distance between New York and Los Angeles.

Annette Fredskov, a mom of two, says that her inspiration for the feat came after she was diagnosed with multiple sclerosis three years ago. Last summer, she made the decision to start running a marathon a day and never looked back. This past Sunday, Fredskov closed the year with a double marathon. 

In an interview on today's Studio B, Shepard Smith asked Fredskov the obvious question: "how in the world can you do this?"

Her response was simple. "With a positive attitude, I just got there!" she exclaimed.

We think it would take us more than a positive attitude. Just sayin'.

Fredskov admitted that she isn't sure that's it's a "healthful" routine, but one thing is certain.

"I haven't been sick for a year, in over a year. No flu, no nothing; I've just been healthy," she said. 

"I didn't do it [to] be healthy, but I am healthy, and that's very interesting."
