When I hit the gym these days, I have been listening to podcasts instead of music. My favorites at this time are:

-Slashdot Review
-Fredcast Cycling
-MacGeek Gab
-World Cup Cast
-Infection Podcast Novel

There are more, but these are the most listened to at this point.

Special note on the last one - Infection - the third podcast novel by Scott Sigler. I highly recommend these pod novels. His first two (Earthcore and Ancestor) were awesome. I am not sure that Infection is his best, but it is only about half way, so I will reserve judgement.

Any one else have any favorites or recommendations...
