Is my AeT the same at higher elevation?

Per the drift test my AeT is 145.

I hiked my first 14er this past week. I kept my HR at 130 for the climb but it felt harder than 130.

Because of how much harder 130 felt I wanted to know if AeT varies with elevation or metabolically is it the same despite how it feels?

Thanks

Good question. Heart rates will vary with elevation.

To what extent, it’s hard to say. For one-time events, it’s best to go by a similar RPE (perceived exertion) to your normal training environment. If you have multiple training venues at different elevations, then doing a threshold test at each is not a bad idea.

For example, I have a client that lives at 8,000′. This week, he’s training at 5,000′. An easy run today was at his 8,000′ anaerobic threshold HR.
