To complicate matters a bit more, it's not just the surface that
matters, but how many dog walkers you're likely to encounter. There's
section of the NCN round here on which, if clear, I could do 15mph on my
25x700c tires, but I avoid it because I'd frequently have to slow to a
standstill to avoid running into dog leads!
