"We Begin Our Ascent," by Joe Mungo reed

Yes, the name Joe Mungo Reed seems rather off-putting, but he is an accomplished writer and clearly has an inside knowledge of cycle racing and how things work on The Tour de France, where his racing cyclist narrator, Solomon, is a domestique, whose aim is not to win stages himself but to help Fabrice, the principal rider of his team to win. To quote a review: "fast, smart, funny and sad, this is an outstanding sports novel and Reed is an author to watch."
The team uses drugs, and when Solomon's wife drives from England to spend a couple of days with the Tour, she also gets involved in picking up a consignment of dope for the team...with unforeseen complications.
