I'm not sure why Clare Balding's sexuality would have anything to do with her interest, or otherwise, in cycling
I think she's doing a good job, for what it's worth, and if we're going to be critical of the 'generic' presenters, I think we'd have a much better time discussing the truly awful and cringe making Adrian Childs, whose trousers are much too tight in my humble opinion
(though, of course, his trousers and the tightness thereof would have nothing to do with his interest in cycling)
