I'm not that bothered by the ads in principle (edit: especially as I usually watch the show recorded so can skip through them) but there are two things that bother me about them:
1. The quotes are appalling sports biog clichés. Are they from his book or something? Clearly, he's a better cyclist than he is a writer. Couldn't they come up with something less generic and hackneyed?
2. Lack of variety. I wouldn't mind so much if there were, say, 20 different quotes on rotation, but when it's just three quotes, so you get to hear each one several times per programme, they very quickly start to grate.
