In addition to being an account of the races, it's also an account of the history of doping and drug controls in the sport of cycling:
I spoke to a mechanic who traveled with a top-flight Spanish pro team in the mid-1990s. What he saw frightened him. The racers slept with heart-rate monitors hooked up to alarms. If a sleeping rider’s pulse fell below a certain rate, the alarm went off, the rider was awakened, given aspirin and a saline injection to thin the blood and put on a trainer to get his heart rate up and blood flowing. This was clearly dangerous stuff at the doses racers were using and everyone knew it, but it had a gigantic payoff to the talented and lucky user. As La Gazzetta put it, there was a change in the hierarchy of some teams: the doctor was now more important than the director. (Loc. 1846-50 )
The author does not refrain from speculation about who might have doped and when, and it adds to the entertainment.
Recommended for cycling fans, but read Volume 1 first.
