Relieved to be out of the Gulf Coast heat and humidity, Dean Karnazes ran his fourth marathon in as many days. Today, the 26.2 mile trek was along the course of the Little Rock Marathon. Once again, Karnazes kept up a blistering pace, coming in at 4 hours and 14 minutes. Mike Huckabee, Arkansas' governor and a recent convert to marathon running, joined Karnazes who now has 46 marathons to go in his Endurance 50 quest to run 50 marathons in 50 days in all 50 states. Next stop: Wichita.
