Does anyone know of an online GPS route planning tool that allows you to map routes using an Ordinance Survey map as your base layer?
Most route planning systems use google maps which is rubbish for off road footpaths. Bing maps do allow you to view an OS map of the area, however the only mapping site that I've so far discovered that uses Bing is Garmin Connect and they don't give you access to the OS map (just 'normal' and satellite).
Open Street Map based systems have very patchy coverage of footpaths and bridleways and therefore don't work for me either.
