Have searched for and listened to a few cycling podcasts over the past months. There are a few American based ones out there which are ok but not really my cup of tea. I'd have to say the Velocast (iTunes or http://www.velocast.co.uk) is superb and during the tour (when they went nightly) became essential evening listening. Anyone recommend any others - always look for a mix between pro cycling news, bike and gear updates, and some humour thrown in.
