I talk with Brandon Bethke about what it takes to run a sub 4 min mile. We talk about the training, nutrition, rest and recovery it takes to reach the elite level in distance running.

Since 1957, less than 350 US runners have broken the 4 minute mile. On February 9th, 2008 Brandon Bethke became the 301st American to run under 4 minutes for the mile by running 3 minutes 59.85 seconds. More people have climbed Mt. Everest than have broken 4 minutes in the mile.
