    so for my own clarification if you do your AeT test on a treadmill you want to compare your avg heart rate on the 1st half to the 2nd half.

    if you do it outside it should be on a flat to gently rolling course preferably not an out and back and keep your heart rate as steady as possible and use the Pa:Hr over the entire test.

    If your % difference on the treadmill is 3.5-5% your at your AeT. If your Pa:Hr is 3.5-5% your at your AeT as well correct?

    also is this is my normal route, good enough for an AeT test? see pictures

    You are right!
    The course is perfect. 26ft up and down very little. This will have no impact on your results.

    Also note that the formula is: [Avg HR 2nd half] / [Avg HR 1st Half]

    That will give you something like “1.09” or “1.25” which would mean 9% and 25% respectively.

    i’m lost on your calculations. can you explain?

    it’s not very clear in this article for outdoors https://uphillathlete.com/heart-rate-drift/

    are they saying take the Pa:Hr for the overall all and the 1st and 2nd half? so if the overall Pa:Hr is good so does the ratio of the 1st and 2nd half?

    If you are testing outdoors, just look for Pa:Hr in Training Peaks (premium account). Pa:Hr is for the duration of the test.

    The calculation that Scott mentioned is for the indoor treadmill test.

    Does this help?

    Yes, I thought he was talking outdoor. I knew indoor was the comparison
