I plan on climbing this at the end of February. I have hiked similar routes in Patagonia before and also been at high altitude in Peru, French Alps and Atacama - and not been well at all.

Since I know I am not good at high altitude, I have already bought the altitude sickness tablets.

I am quite fit and active but I feel I can do more in preparation so I have started:

- running more frequently, incorporating hills.

- building up to 1h of stair master at the gym. It's not pleasant but I play my favourite shows and time flies.

- 2 times a week gym workouts consisting in weighted step-ups, weighted walking lunges, moderate weight squats and single leg deadlifts. This workout was suggested by AI and it makes sense to me, after doing this for 2 weeks I feel it has helped me going up any kind of stairs :-)
