@the_spokeswoman I'd follow the Cyclestreets routes, no worries. Important to realise that Cambourne is 70m above sea level so it's a climb out of Cambridge, particularly from M11 bridge to American Cemetery. Up hill almost all the way there, which makes it a comfortable ride back :-)
@AdamBronkhorst Cambridge city has quite a good guide, needs updating but a good start. See https://t.co/PosVGy4UIL . Personally I'd ban all 2-tier stacking racks
