Any question answered...

what are the best/ your favourite websites for mapping routes?

ideally:

• will plot a route, with info about roads and cycle lanes (like cycle streets)
  
• can modify the suggested route (like googlemaps)
  
• can draw your own bits eg. for when the website doesn't know there is a cyclepath there
  
• elevation info
  
  

I like bikemap.net, but by the time I write this it may well have been superseded--there seem to be new ones all the time. The only thing I don't like about it is that the resolution doesn't go down far enough, but for everything else I think it's pretty good.
