There were over 20,000 competitors in Sunday's Nike Women's Marathon in San Francisco. And 24-year-old Arien O'Connell, a fifth-grade teacher from New York City, ran the fastest time of any of the women.
But she didn't win.
Something similar happened at the Chicago Marathon on October 12. More details in the article, but the gist is that the person with the 4th fastest time didn't get the prize money for fourth place because he didn't run with the elite runners.
