50 marathons in 50 days in 50 states!

This is just insane! . The thing I found crazy was that he added an extra marathon one day...for fun? Also of note, he averages a little under 9 minutes per mile. At any rate, I am just training for only one marathon. I ran a sweet 16 miles yesterday for the long run. I am headed to 18 miles next Sunday for the next long run. No where near the 50 insane marathons this guy is doing.
