One man is no stranger the TCS New York City Marathon, but this weekend's race will push him to new limits.
Glenn Hartrick's first New York Marathon was a life changer -- he was hooked. His weekends filled up with races and took him to the IronMan finish line. Anything was possible.
Then a terrible accident on the New Jersey Palisades seemed to be a tragic end to his sports life. But it actually put Hartrick on a trajectory that could land him in the history books on Marathon Sunday.
