Ullrich to discuss doping in a book?

Jan Ullrich will answer the question "Did you dope?" in a book he wants to write, saying, "This question is not easy to answer." In an interview with the German tabloid BILD am Sonntag, he also indicated a possible doping usage when he rode, when he said, "Whoever still can't put one and one together about what happened in cycling is beyond my help."

Ullrich retired in February 2007, after being suspected of involvement with Dr. Eufemiano Fuentes. Blood taken during the Operacion Puerto was matched to him via DNA testing.
