Here for rides.
I had given this some thought. It's not the first eighty miles to Launceston that bothers me so much as the Launceston to Exter stretch (once through Exeter the road on to Bridgewater is a lot of fun). It seemed to me (and this isn't a plan, merely a thought) that an early hours start from Launceston, leading to an extended breakfast in Exeter, an extended lunch in Taunton and an extended high tea in Bridgewater might be good....
Launceston to Exeter isn't bad at all, I'd go so far as to say it is a delight, if you simply keep off the A30 and use the 'old' road instead. It is described here in another place by the splendid Mick F of the CTC. I've ridden it both ways in August. Proper Job.
