OK, so the ride org read the above post and was perfectly happy for us to do the ride. In fact he gave us advice on some route modifications, if riding on a weekday.
Thanks Joe!
So I met newtoncap this morning and we did the circular bit of this ride from Lanchester. I had such a great time. The roads are some of the best I've ridden, bar none, and it was HILLY, but so so worth it. Two excellent cafe controls. I'm pleased we defied the severe weather warning, because although we both got repeatedly soaked, it wasn't cold, and the autumn skies made the scenery even more spectacular, if that were possible.
I would really like to be fit enough to do the 200 next year, but that is a big ask. A very, very challenging route, but rewarding.
Very highly recommended.
