This episode airs on November 28. That means Mark is running 28 miles today. Tomorrow he'll run 29. The next day? 30.

Mark Dowdle is attempting to become the FIRST EVER person to complete the Calendar Club 365 Challenge -- where runs the same number of miles as the day of the month, every month, for one year.

I've been following Mark on Instagram for some time now -- you should too, check out @mark.dowdle -- and was so impressed, I just had to speak with him.

Enjoy what he had to say about the challenge, about running, and life in general.
