would like to introduce a good bike route planning tool, via tour.Xplova http://tour.xplova.com/, I use this tool to plan Tour of Utah Stage 5, http://tour.xplova.com/routeDetail/?GUID=80860C47-A29D-2599-1615-B83F39038F39 , I can check the detail elevation profile versus distance variation, I can also click the play button to see the 3D simulation.
