Well, the weather was great, but I went the wrong way! Anyway, as I had a map with me, I worked the lanes to the east of the A41 and had a good ride. 110km in total, with about 4:40 riding time, and about 5:15 total time. With my untrained legs, the last hour was hard work!
I now need to plan what I will do next weekend to build on this ride.
