Cosmo Happy Hour

What's the difference between someone who can barely run a mile — and someone who runs 100 miles? Cosmopolitan.com health editor Elizabeth Narins and host Elisa Benson talk to special guests Jes Woods, an ultramarathoner, and Jessica Lynn Marino, an elite endurance athlete, about the small but growing world of young women who accomplish mind-blowing athletic feats. Warning: This episode is probably going to make you cry.
