70 miles. Mostly (90%) national speed limit roads with pretty villages to ride slowly through. Not many fast straights but SO MANY long fast bends and lots of testing twisties . Beautiful N Devon rolling countryside to catch the corner of your eye. Ride this at leisure for pleasure or fast for major grin! Avoids the major holiday fraffic roads so traffic is usually light and no end of overtaking places . Can´t go wrong. Today the route took me 90 minutes which does not include a 10 minute stop at the petrol station in launceston(just around the corner from the mini -roundabout).
