at least it was dry for me, but i came up with a neat trick....
i always seemed to go faster on a twisty stretch than a long straight, i thought it was the surface, or the shelter (lots of trees) but actually it was because the long straight was demoralising - so i worked out that if i looked at the computer instead of the horizon on the straight, i stopped losing speed
oh the joys of doing a 10 mile loop repeatedly!
