Oprah Winfrey killed it when she ran the Marine Corps Marathon in just 4:29:20 back in 1994. Of course, like everything else Oprah does, she managed to motivate tons of women in the process. Apparently Diddy was trying REALLY hard to beat Oprah's time during his marathon run, which he did by a mere 14 minutes. Whatevs, Oprah still rules you, Diddy. [Complete Running]
