Dean Karnazes Runs 5 marathons in 24 Hours! by Auritt



Back
The official first day of summer got off to a running start in the heart of New York City when the Ultramarathonman Dean Karnazes braved one of the greatest tests of endurance in history. With the support of Accelerade, a new protein-enhanced sports drink, Dean ran almost 5 marathons in 24 hours! And he did it all on a treadmill suspended high above Times Square.
