Start by having a day off!!
Sounds like we made all the same mistakes. Not spotting the best routes on #4 and #7. Wasting time looking for unnecessary crossing point at #12 and, of course #1. I was too high but obviously realised quicker than you.
I wouldn't say I was taking it that seriously. X-C the day before for the first time in a few years can't be ideal race preparation. Neither can a beery night at a Blondie tribute act...
Yes, same mistakes, but you dealt with them much better than me. Each time I was just thinking I can't be bothered rather than sorting it out.
Straight was much faster on #4: I was 80secs quicker and you wouldn't have run that line slower than I did.
