Whenever I go a long period of time without running, I always start back with the couch to 5k training schedule. I know many others on here like the c25k here too.
I was searching around iTunes podcasts and found this guy who made podcasts for each week of the c25k... there is some techno-ish type music and he tells you when to run and walk. I've always hated looking at the stopwatch on my ipod to figure out when to run and walk, it always kind of drove me nuts... now I won't have to!!!
I highly recommend it!
Hopefully I'm not telling you all something you already know lol
The podcast is called "Podcasts for Running"...

Though the timing cues seem key...
