NYC Marathon winner Shalane Flanagan on her diet for endurance
Shalane Flanagan won the New York City Marathon last year, making her the first American woman to achieve that feat in decades and inspiring other American women to follow in her footsteps. The four-time Olympian is now an author for the second time. She co-wrote the cookbook, “Run Fast. Cook Fast. Eat Slow.: Quick-Fix Recipes for Hangry Athletes.” Norah O'Donnell reports.
