William Nack is an American journalist and author. He wrote about sports, politics and the environment at Newsday for 11 years before joining the staff of Sports Illustrated in 1978 as an investigative reporter and general feature writer.
Since leaving S.I. in 2001, Nack has freelanced for numerous publications, including GQ and ESPN.com. He also served as an adviser on the made-for-TV-movie Ruffian (2007) and the Disney feature Secretariat (2010).
Like a star streaking across the sky, Secretariat and his racing glory was one of those "once in a lifetime" experiences you feel fortunate to have witnessed. Reading the nitty-gritty details behind the mechanics/emotions/stress/danger/risk of thoroughbred racing was fascianating to me. It's a world I'll never be part of, but Nack brings it to life so I can live vicariously through his magnificent descriptions of such historic events.
