Following is a section from Doping at the Tour de France from Wikipedia:
In 1924 the journalist Albert Londres followed the Tour de France for the French newspaper, Le Petit Parisien. At Coutances he heard that the previous year's winner, Henri Pélissier, his brother Francis and a third rider, Maurice Ville, had pulled out after a row with the organiser, Henri Desgrange. Henri Pélissier explained the problem - whether or not he had the right to take off a jersey - and went on to talk of drugs, reported in Londres' race diary, in which he coined the phrase Les Forçats de la Route (The Convicts of the Road):
"You have no idea what the Tour de France is", Henri said. "It's a Calvary. Worse than that, because the road to the Cross has only 14 stations and ours has 15. We suffer from the start to the end. You want to know how we keep going? Here..." He pulled a phial from his bag. "That's cocaine, for our eyes. This is chloroform, for our gums."
"This", Ville said, emptying his shoulder bag "is liniment to put warmth back into our knees."
"And pills. Do you want to see pills? Have a look, here are the pills." Each pulled out three boxes.
"The truth is", Francis said, "that we keep going on dynamite."
Henri spoke of being as white as shrouds once the dirt of the day had been washed off, then of their bodies being drained by diarrhoea, before continuing:
"At night, in our rooms, we can't sleep. We twitch and dance and jig about as though we were doing St Vitus's Dance..."
"There's less flesh on our bodies than on a skeleton", Francis said.
Francis Pélissier said much later: "Londres was a famous reporter but he didn't know about cycling. We kidded him a bit with our cocaine and our pills. Even so, the Tour de France in 1924 was no picnic.
