Dean Karnazes is unbelievable (I first wrote about him at And I Thought It Was A Big Deal To Run A Marathon).
Here's a short piece from Runners's World (How Did Dean Do?)on his latest gig: an attempt to break the record for most miles on a treadmill in 48 consecutive hours. He didn't get the record but did manage to finish 211(!!!!) miles (short of the record by 2 miles).
I'm reading and enjoying Karnazes' latest book: 50/50: Secrets I Learned Running 50 Marathons in 50 Days -- and How You Too Can Achieve Super Endurance!, in which Karnazes tells the story of running 50 marathons in 50 states in 50 days. Aside from being a great story about how he pulled off the 50 in 50, there are plenty of good running tips - for marathoners and non-marathoners. Check it out!
