Running in Freiburg – I can see the track from space now (and much clearer)

A few days ago I played with laufrausch.net, a web community where you can publish routes you like to run on Google Maps. So I created a running route along the river Dreisam in Freiburg. Unfortunately the GMap was very blurry. But today I read on Netzeitung that a higher resolution for Freiburg is available. Now I can compare and I must say, the route I created fits the map pretty well.   But maybe I can optimize it. So… where can I move the waypoints on an existing route now in laufrausch.net?
