Sounds like you’ve had a tough go. I hope you are recovered. If you are completely well I would definitely add in some Muscular Endurance workouts in the these final weeks. While your base has probably eroded you do not have time to rebuild it and you do need to do some harder endurance oriented work to prepare for the climb.
Try to keep the base volume (Zones 1-2) high during these weeks as well. You may surprise yourself at how well you bounce back. But you’ll want a taper of a week from your last ME workout before the climb.
