I think the best way to learn is to watch the Famous Cycling Videos (or World Cycling Productions) videos. I’ve read a bunch of books on The Tour but no spectacular one jumps out at me. Anything by Samuel Abt is pretty darn good since he is such a fine writer. He wrote at least one book on racing The Tour during the Indurain era. That book was fascinating. Armstrong’s new book (as well as his previous one, “It’s Not About the Bike”) titled “Every Second Counts” (I think?) is probably pretty fun also. I’ve seen it, but haven’t read it. Try to search on Amazon under author “Samuel Abt” and see what you come up with. I think john Wilcockson of Velo Press/ Velo News has a couple titles but, compared to the elegant literary style of Abt, it is dry as a popcorn fart.
