Kyle:

What kind of warm-up did you have before they started taking lactate samples?  I do not see how we could call AeT 160 since your lactate never stabilized and lower heart rates. It rapidly rose from the get-go.  Normally one will call the AeT the point either where LA goes above 2mMol/L or where its initial rise of 1mMol/L occurs.

I strongly suggest you do the HR Drift test as described here: https://evokeendurance.com/our-latest-thinking-on-aerobic-assessment-for-the-mountain-athlete/

Do that test hiking on a treadmill set at 15% and use 135 as the starting HR.

From the chart you have sent 160HR indicates a LA of 3mMol/l.  That is well above any definition of AeT.  Based on this test I would call AeT 135ish because that is where LA started climbing.

The above comments on this test are null and void if you didn’t have at least a 10min gradual warm-up.
