At the risk of this getting boring for everyone except me, here's some more numbers comparing my ride this year with last. The column of interest is compare, which shows mile-by-mile whether I was in front (black) or behind (red) my time last year. The last column shows where on the course that mile is. I think this pretty much rules out some of the stuff I said in my report... I made up most time over Wort's Hill, where I remember last year getting stuck in a big queue of people, and having to walk over the hill. Also made up time climbing the steep road on Huck's Hill. Put that down to lighter bike? Interestingly I lost time on the Wessenden Head climb - strange because that didn't feel any slower, although the last bit was tough so maybe I was more tired there this year. The road descent off Wessenden Head maybe was indeed the tyres. But the differences are a lot more concentrated in a few significant places than I expected. Hmm. It is very interesting nonetheless to have done exactly the same route, in similar weather conditions, a year apart.
