Hey Geoff !!
Good Luck on your route. I statrted the trip last April, but because of the crazy weather last winter, I got stopped at Moortown in Somerset by the Police who were redirecting me to Glastonbury -18 miles the wronge way off of my course - and who wouldn't grant me an escort through the town - it was deserted because of the floods
BUT .... I'm planning my retake for next March/April or even May !!
I'm currently regaianing my cycling juices and recharging my enthusiasum ... Good Luck for May 1st Hun, on that day I shall be starting my fitness campaign to loss 2 stone and get fit and get back into cycling around my beloved county of Devon
Have fun, enjoy the journey and stay safe !!
