The first one I have listened to for a while now (and have mentioned before) is the Jillian Michaels podcast - not because I'm a closet north american, not because I'm a huge Biggest Loser fan, and not because I am a woman of a certain age... just because it is generally silly, but informative, and benign whilst insightful. I am sure many people have said many things about the 'show' and I am certainly not going to critique it here.
The second one I have been downloading has been a revelation - Marathon Talk - for me at the moment simply perfect listening and simply perfect content. As someone hoping to run two marathons this year it has been a brilliant find for tips and training ideas / guides. The running advice is coupled with some absolutely brilliant interviews, and since I started listening over the New Year I have heard some crackers with Kelly Sotherton (former GB heptathlete trying her first marathon after retiring from elite sport), Mike Tomlinson (event organiser and husband of the late Jane Tomlinson), Amby Burfoot (RunnersWorld guru, and lifelong runner), Prof John Brewer (sports physiologist), Brett Larner (the guy behind Japan Running News), and Kurt Fearnley (paralympic athlete) this year, and I haven't begun dipping into their archive yet.
I have taken so much from the Marathon Talk podcasts that I would recommend a listen to any runner. It is true that the podcast it is supported / funded by Adidas but it is not by any means an ad driven enterprise it comes across as genuinely about running community, and the two hosts (Messrs Martin Yelling and Tom Williams) are warm and engaging. I have yet to find time to root around the website but I have the feeling that when I do it will be similarly rewarding.
Both of these are available through iTunes just stick something relevant in the search do-da :-)
Diary - very busy in work (not a bad thing), very busy at home (also not a bad thing), not getting many miles out on the road (not a good thing). I'm 10lbs lighter than at the end of December, and moving towards fuller training. Weather - cold, windy, and possibly bringing more snow our way.
