Another Vote for The Cycling Podcast (and “Friend” subscription).
I also pay to subscribe to the Velocast (velocast.cc).
I also regularly listen to Cycling Tips and the Velonews podcasts, although I have found the constant pushing of periodisation meaning I’m less inclined to listen to it than I used to - I’ve taken a great deal from it in the past, I just think he’s going too all eggs in!
Food For Fitness and Sigma Nutrition for, eh, nutrition.
I occasionally listen to The Move. I don’t really warm to him though, but I think he’s right in the Tour Route one saying radios and Power meters shouldn’t be banned, but they should be open access!
