Just found this online, from Ernest Hemingway's 1926 novel, The Sun Also Rises:
"There was a bicycle-race on, the Tour du Pays Basque, and the riders were stopping that night in San Sebastian. In the dining-room, at one side, there was a long table of bicycle-riders, eating with their trainers and managers. They were all French and Belgians, and paid close attention to their meal, but they were having a good time. [...]
The next morning at five o'clock the race resumed with the last lap, San Sebastian-Bilbao. The bicycle-riders drank much wine and were burned and browned by the sun. They did not take the race seriously except among themselves."
