In a fit of irritation I wrote to Coyle asking him why he had painted a picture of the cyclists that did not exist.
"Do you know how widespread drug use in cycling is?" I asked, "and when are you going to write about it?" Where London Sunday Times journalist David Walsh had confronted the issues, "you seem to have skirted around them".
I was amazed when Coyle responded to my rather blunt email, acknowledging the points I had made. He said he was struggling to reconcile the two realities of cycling. "In the wake of all this, I'm not champing at the bit to write about the sport again. Unless someone were to come clean and let me inside - paging Floyd? - it remains in the shadows," he wrote.
Five years later one of Armstrong's former teammates, Tyler Hamilton, let Coyle into the world of doping in professional cycling in a new book called The Secret Race. Finally Coyle was able to write the real story.
However, the real hero in the Armstrong saga is David Walsh, the Irish sports writer, who was ostracised 13 years ago for daring to suggest that Armstrong was a cheat. Truthful journalism is always vindicated in the end.
