Actually, to start with, I was feeling pretty good, but pretty rapidly I found my pulse rate soaring, furst up into level 2 (so far, so good), but then onwards into level 4. The opening mile or so seemd good, and I felt quicj, but I just lost it climbing towards Nash - I tried to keep the gearing down, but this just led to slower speeds! After turning, the bigh descent from Nash to Beachampton was harder than usual, as I failed to get the speed up (and was seeing very high pulse rates - on a descent!).
The final insult was to get stopped dead by a white van right at the last turn before the finishing straight. I finished with a disappointing 27:49. Other news - Gilbert came a cropper somewhere out on the course but remounted and finished (thereby assuring his nickname of "Hard Man of the North") - but looked a bit groggy at the finish.
Full results to follow.
