Sport: Running
Career Years: 1980
Career Lowlight: Stripped of Boston Marathon title.

To be honest, we find Ruiz's incredible two race career to be one of the most remarkably impressive grifts in history. Not only did she cheat to qualify for the Boston Marathon, but she successfully pulled it off again in winning the 1980 women's race with a 2:31:56 time that would have made her the fastest woman in Boston history. Her decision to hang out in the crowd before bursting onto the course was probably not the best idea for someone trying to be sneaky, though, and her victory was quite short-lived. Nevertheless, we can't blame her for trying.
