What’s more key at that point is the gear, which they should provide you a list and do checks to make sure you have what you need so you won’t kill yourself, and fitness level - that is non negotiable and might take a while to build to
The people I’ve done these trips with that do endurance training (distance running, cycling , even rucking) all fare very well.
The guys who go to the gym 4x a week to do a bro split lifting routine and whose cardio consists of a beer softball / volleyball league and the occasional 3 mile jog at a 8:45 pace almost always come in cocky and get absolutely destroyed before the halfway point
In the year prior to a winter Katahdin summit I was in good enough cardio shape to do a 3 hour marathon, yet doing a day climb of that mountain was still the most physically challenging endeavor of my life.
