I’m personally not a big fan of listening to music while running — except on the treadmill. But I know that a lot of people find running without music as crazy as running without shoes… wait, I do that too. Anyway… Nike just launched a new version of their iPhone/iPod Nike + GPS Touch app. Thought you might want to know about it. You can download it here (iTunes link).
Though my Nike Free do support the little in-shoe foot pod thing, I have not tried it. However, I’ve read and had runners tell me that it’s pretty good. The interface design is pretty stellar and it’s socially connected so you can share your workouts with people on Facebook.
It apparently also offers in-run motivational messages from athletes to help keep you going. Kinda cool.
