I train at sea level for yearly trips to the Alps. My objectives next June will be a bit different from the rock routes I’ve been on in the past. I plan on climbing the Frendo and NF of Tour Ronde and similar objective that involve many pitches of lowish angle ice and neve. I’m wondering what beyond my typical core and general endurance conditioning I should do to prepare. Any ideas?
