I actually have a "real" walking cassettetape...bought it some time ago.....but I know there is stuff on the web. Mine is some sort of oldies stuff I think, but there are all kinds.

The good part is....is starts off with a 10 minute warm up "beat"...then beat increases to 4mph beat for another 45 minutes (or however long you want to walk). I know it keeps me "honest" and that I'm not slowing down or speeding up and getting a proper workout! This is considered "intermediate level"...at least that is what is states on the cover, but there are also beginner and advanced levels with corresponding speeds for those needing different workout speeds!
