Hamilton's and Coyle's book "The Secret Race" was described as a "book which has changed the sport of cycling," at the award show in London, Great Britain.

The book details how Hamilton made use of doping throughout his career as professional cyclist. Hamilton and Coyle jointly spent 18 months working on the book which tells the story of "doping, the lies, and a decade spent running from the truth," as William Hill spokesman Graham Sharpe described it to Roadcycling.com.

"I'm deeply overwhelmed," Hamilton said at the show. "I'm very proud of having written the book, but not proud of what's being described in it. But it is the truth and the truth deserves to be said."

The Secret Race is also implicating Hamilton's former Team CSC manager and current Team Saxo-Tinkoff manager Bjarne Riis in the blood doping practices of Dr. Eufemiano Fuentes. As a result, Riis is now under heavy pressure from the media and public in his home country Denmark.

"The Secret Race" is the third cycling book to win the William Hill Sports Book of the Year Award. In 1990 Paul Kimmage won the same award for his anti-doping book "Rough Ride" and in 2000 Lance Armstrong won the prize for It's Not About The Bike, which he co-authored with Sally Jenkins.
