— -- Elizabeth Vargas’ Exclusive Broadcast Interview with Suzy Favor Hamilton Airs on the Season Premiere of “20/20,” Friday, September 11 at 10 pm on ABC

Three-time Olympic athlete Suzy Favor Hamilton seemed to have it all: a highly decorated running career, numerous high-profile corporate sponsorships, a marriage to her college sweetheart, and a healthy young daughter. So what would lead her to a shocking double life as a high priced Las Vegas prostitute? In her first broadcast interview tied to the release of her memoir Fast Girl: A Life Spent Running From Madness, Suzy speaks exclusively to Elizabeth Vargas about the self-doubt she harbored for years, and what fueled her high risk behavior and secret life. Vargas also speaks to Hamilton’s husband Mark, who not only knew about her life as an escort, he stood by her side. Vargas’ report airs on the SEASON PREMIERE of “20/20,” FRIDAY, SEPTEMBER 11 (10:00-11:00 p.m., ET) on ABC.

“20/20” is anchored by Elizabeth Vargas and David Muir. David Sloan is senior executive producer.
