There is a reason why I have not been using Google Maps directions for bike routes, heh-heh. Sure got into a mess with this!
Update – this came about because I was editing the reccomended route that Google Maps had provided. It is actually excellent to use with car routes but trying to adjust it for the intricasies of a cycling oute is silly. I got into more and more trouble and became all tangled up! For cycling routes, just use bikely.
