You're talking about resistance exercise here, and that is a factor. But
remember, events that are considered to be anaerobic (60% anaerobic
metabolism) can last only about 2 minutes. Events lasting longer than 3
minutes are mostly aerobic. Events lasting an hour or more are almost
exclusively aerobic with almost no fuel depletion observed in FT muscle
cells.
So, if your horse becomes fatigued at 3 minutes of carrying your weight at
your chosen speed, I will agree with you. If not, then something else besides
anaerobic metabolism is at work.

There is truth and there is "I'm OK, You're OK" reasoning. I want my thinking
to eventually boil down to the actual laws in play. There is no fuzziness in
this game--it's all quantifiable. For example, tell me what your 90 second
post-ex heartrate is and I'll tell you if you've crossed your horse's
anaerobic threshold. If not, then you have some thinking to do about
conditioning, muscle fuel availability, body heat, etc.--no use worrying
about non-existant threats. My philosophy: never bring a knife to a gunfight.
