The menu item "Route" opens up an administration page for all routes. If you have already entered some routes, these are listed here.
Clicking on the route names or "View route" brings you to the route overview. In "Edit mode" push the button from left to right (it then turns green). Your route is then found in the Edit mode.
You can now delete or add the title, the description or waypoints or put them in another order and also modify the visibility settings for your route.
