Just 5 more days. Just 5 more marathons. Dean Karnazes has nearly completed his Endurance 50 quest to run 50 marathons in 50 days in all 50 states. Yesterday, he ran the Kiawah Island Marathon in South Carolina. Today, he ran the Triple Lakes Trail Marathon in North Carolina. Tomorrow, he'll be in Maryland before making his way to Deleware, Pennsylvania, and New Jersey. Then, for the grand finale, Karnazes will run with 40,000 other marathoners--including celeb first-timer, Lance Armstrong, in the ING New York City Marathon.
