I've *stupidly* signed up for the long distance Alpe d'Huez next month and starting to panic. I currently run 11-28 with compact chain ring but think I should swap out the cassette (and rear mech) if I have any hopes of finishing this race. Is 11-34 what I should switch to? I'm comfortable climbing with the 28 up to around a 9% grade. Beyond that, I'm definitely mashing and reckon I'll be unlikely to start the run with anything beyond a shuffle.
I'd equally welcome any other nuggets of advice for this race!
