Nobody said anything about BIG hills.
Anyway, internet abuse didn't come up in my appraisal so I'm back with more time to spare.
I have a triple cos I'm old and have knackered knees, and tend to stay seated, spinning away at a pace I know I can sustain for the whole hill.
I only go up a gear and get out of the saddle
i) to give my legs a change of scenery
ii) if I'm in my lowest gear and still struggling seated
iii) if I'm blasting up a short incline
iv) if I'm passing someone I think should have a better view of my @rse.
