Thanks for the recommendations, I ended up going from Leeds to Harrogate, then Ripon, then Masham. By the time I got there it was quite dark and I was getting hungry and running out of fuel. So I missed out on riding the road between Masham and Leyburn. Even though it was dark I enjoyed the ride back, the temperature was perfect for a ride and at that time there was very little traffic. I got a chance to use the Philips MotoVision bulbs to their full potential, they are much better than normal bulbs.
