<Li> Men's Journal, Adventure Hall of Fame, 2007 </Li> <Li> Outside magazine, Ultimate Top 10 Outdoor Athletes, 2004 </Li> <P> In 2006, Karnazes embarked on the well - publicized Endurance 50: 50 marathons in 50 states in 50 consecutive days . Beginning with the Lewis and Clark Marathon in St. Louis on September 17, 2006, it finished with the New York City Marathon on November 5 . Eight of the 50 races were conventional marathon races . Since marathon races are typically held only on weekends, on the other days Karnazes (accompanied by between one and 50 runners) ran the course of a marathon in each state using the help of the race director and staff of each event to officially run the certified course, but on a different day than the "live" event . (For example, as part of the 50 / 50 / 50, Karnazes ran the official course of the Boston Marathon, but not the race itself, which is held in mid-April .) </P> <P> Karnazes overcame the endurance and logistical difficulties of this goal and finished the final marathon, the NYC Marathon, on the official race day in 3 hours and 30 seconds . He weighed 154 lbs (70 kg) at the start and 153 lbs (69.5 kg) at the end . </P>
