Jared: Thanks for writing in with your questions. I comment below:
1. While approaching the climb, does this time count towards higher intensity zoned training? Muscular Endurance? Strength? YES. All of these. It is a mix of everything you need in training all done in one workout. Not a bad thing but I would not suggest doing this this 3 days a week 🙂
2. Let’s say this approach took 1 hour. Does that 1 hour get weighed in the ratio against my other sub AeT training hours? YES.
3. Could overdoing this type of approach (relative to sub-AeT work) lead to loss of aerobic base? YES, See #1 above.
4. Regarding the actual climbing, does this count as higher intensity zoned training? Muscular Endurance? Strength? YES AGAIN. This is what we call utilization training. A little is good. Too much is bad and will have a negative effect on your Capacity building training.
5. How do you think of quantifying HR zone while lead climbing, if it is subject to physical exertion and the stress of the sharp end? Both I am sure.
6. Are there any additional thoughts on how I should think of this sort of outing, either the approach or climbing, in terms of quantifying training load or balancing against other stimuli? Read this article https://uphillathlete.com/capacity-training-vs-utilization-training/
