Hi there. I've recently used cycle.travel to plan my UK West to East cycle tour (Ardnamurchan Point to Lowestoft Ness). I created and saved routes for each day checking mileage and ascent - essential to plan overnight stops. I then printed a pdf map for each day to follow on my bar bag. I also downloaded a gpx file and uploaded into Guru Maps Pro - just for reference in case I got lost (which increasingly happened in eastern England). Occasionally I overrode the suggested route but usually found this reduced cycling pleasure!
My wife and I used cycle.travel four our 8-day tour of Suffolk and Norfolk on Bromptons last year and are doing the same this year. A smashing resource. thank you.
