That's pretty cool DRMAT, looks like a nice easy application. There is one for the ipod that works the same/similar way as the nike+ipod setup, forget what it's called.
Is it Run Keeper? Thats what I have. It does a good job for what I want.
It would have been handy back in my Uni days so I could look at the map and know why it took me 3 hours to walk home after a night out.
