Looks like a great schedule you’ve got laid out with some admirable goals. All of these will benefit from improving your ability to move faster for longer in the mountains. What does that mean for your training prescription? We have a saying here at UA: “You can never have too much base”. Keep piling on the basic aerobic work, supplemented with some higher intensity once you’ve boosted AeT to with in 10% of AnT. Keep up the general strength workouts too.
Start mixing in ME workouts now for your Shasta trip and then sprinkle those into the plan between trips. You’ll feel the difference in you speed in the mountains.
This long term progression of base building is exact what I do with the elite level athlete’s I coach. Then when they are within a couple of months of a major goal we focus in on the more even specific workouts.
