How can you run this fast for this long?! This video proves you can!

Yesterday was the Boston Marathon and it came down to a flat out sprint at the end! The guy who won barely edged out the runner up but what is more impressive to me is how fast they ran! The winner finished in 2:07:57! That insane! It is the equivalent of running on the treadmill at 12.3mph, on a 4 percent incline for 26.2 miles!!!!!!! That is psychotic!
