Trailer: Rookies vs The World

Shalane Flanagan, Simon Bairu and Tim Nelson are about as decorated as track athletes can be, with an Olympic bronze medal, multiple national records, and too many All-American honors to count, between the three of them. But on November 7th, these world-class athletes will be rookies all over again, as they race 26.2 miles for the very first time, at the world's greatest marathon: the ING New York City Marathon.

Follow their journey as they prepare for the race in beautiful locations all across the United States, and share in their hope, their anxiety, and, with a little bit of luck, their triumph.
