I've tried listening to talking books while I run, but I don't like talking books per se, so it doesn't work. I just wear an MP3 player hung round my neck and listen to music and/or the occasional podcast as I run.
I also like to carry a dictaphone in my pocket when I'm out running (and to wear something that has a pocket, to keep it in, preferably zipped up). Things occur to me when my mind is in running mode that get lost and forgotten if I don't have the means to make a record of them there and then.
