<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>
