A few years ago, I lived in South Wales and used to do hill repeats up a 15-20% grade climbing out of the saddle at 60-70rpm. Coupled with running it meant that steep grades used to be my specialty - I’d find the steepest bits of tarmac and launch myself up them with gusto (steepest ramp I’ve found is 37%).
Anyway, fast forward to today. I live in Liverpool, which is pan flat. I visited North Yorkshire (where this year’s worlds will be) and found the regular steep grades incredibly fatiguing for my lower core and hips.
Other than just doing loads of steep grades, what are good training or exercises to improve that conditioning?
