You’ve made great progress for your first year especially coming from a sport that does not carry over much to alpine climbing. The aerobic base training can continue during this climbing intense block. The only thing I see in your weekly plan that gives me concern is the 2 ME workouts. What are these? Why 2 of them? I’d recommend delaying adding ME especially 2 of these and especially if they are leg oriented while trying to build the aerobic base. Concentrate more time on Z1-2 over the winter and save the ME for spring in prep for the Alpine trip.
