Runkeeper Logo Concepts

As a design exercise I tried a few quick ideas for redesigning the Runkeeper logo. Runkeeper is a great app that I used to use a lot more (when I ran a lot more), but the logo always bugged me.

Their current logo plays off of the "path" idea (at least I think that's what it's doing) and I thought there was a better way to implement that. I also tried a couple focusing instead on running and movement in general.
