Chris and Amy discuss the historic performance of Ruth Chepngetich, of Kenya, at the Chicago Marathon, where she became the first woman to run under 2:10 with an astonishing time of 2:09:56. They compare her feat to other iconic sports moments, such as Neil Armstrong's moon landing. The hosts also address the shadow of doping concerns in marathon running, given Kenya’s past with performance-enhancing drug violations, and examine what this achievement means for the future of the sport.
