My co-worker sent me a link to Jog.fm, a site that has a whole bunch of running songs and information about which pace each song is best suited for based on its beats per minute.
You can build playlists to suit the pace you want to hit, or the length of time you want to run. You can browse others’ playlists and map your runs, too!
I’ve only browed this for about 5 minutes, but it seems pretty great! Check it out!
