Podcasts for Running?

Hello MF Pals! I'm looking for a podcast for running (preferably with intervals). I started running with the wonderful Podrunner (DJ SteveBoy) and did the C25K and F210K. Now I've graduated to training for a half Marathon and I'm looking for something else to use. I loved the interval chimes they use. *I also choose not to have a smartphone and use an MP3 player.

I'm feeling stuck. Any ideas?
