When you are our for many hours a day for ski touring and day after day I suggest you limit your self to staying at and below your AeT HR. Getting sucked into a pace that is too fast early in the day or the trip for you will only come back to haunt you later. Your aerobic work capacity is what it is and exceeding it,especially early in the trip when the excitement is high and no one is tired yet could be a a very costly mistake. Unless you plan to take a day or two off mid week I’d recommend not exceeding AeT by more than 5-10 beats for more than 10-15 minutes.
Have a great trip.
