any good ones i should check out...i listen to cycling 360 which is quite good, but the drawl of one of the presenters is a bit irritating
check out http://velocast.cc/ - mostly premium content but I quite enjoy their 'This Week in Cycling History' which is free.
Agree with Velocast, best entertainment you can listen to for cycling. They do a FTA Eurosport podcast, Tech 5, premium content as well as TWICH .
Other reasonable podcasts are Velovoices, Rouleur, The Spokesen and a London centric The Bike Show.
Velo Club Don Logan is also well worth listening too.
