Because it can be tiring always jogging to Amy Grant's 1992 Christmas album, this sweet new site outta the Hub uses Beats Per Minute data to match tunes with your run/walk/cycle mile pace (8min mile? Eminem's "Lose Yourself", obv), as well as provides complete downloadable playlists based on total workout time and -- in order to calculate how far you've run -- an easy-to-use mapping tool (that's what you get for trying to please everyone, Rand McNally).
