Heart Rate Drift Test

    Evening all,

    Just completed my first heart rate drift test. My average heart rate over the course of a little over an hour was 155bpm. My percentage ended up being .67%, so I was obviously under my threshold by a decent margin. There was no elevation gain on the trail and the gps appears to have been accurate. I was using a Polar H10 strap in conjunction with a Forerunner 245. Does anyone have any suggestions as to what my aerobic threshold would be or was I too far off to really make a guess.

    Worth noting, I chose my heart rate based on being able to breathe through my nose for an extended period of time as well as being able to speak a full sentence without breathing interrupting. Had I been at say 160bpm, I would not have been able to speak full sentences as easily. I guess as a newish runner I’m just struggling to figure out what a “comfortable” pace is. I do a lot of high altitude hiking in the summer, but this past month is when I have transitioned into running.

    Any insight is much appreciated and I can provide any other details or data I may have left out.

    Hi aquiring93,
    .67% seems very low to make a judgment on its own. As per the suggestion here, your best bet is probably to re-run the test at 160 bpm and check the Pa:Hr again. Assume you’re doing at least a 15 min warm up and then a one hour test.

    Can you share the training peaks link of your test?

    Here is the link to my test…I started my measurement at the 20 min mark and ended it at the 1:20 mark.

    Thanks for sharing the link. For the duration of the test your heart rate drift is around 1.54%. From one hour test starting at minute 25 (heart rate stable around 155), the drift is just above 3%. I think 155 would be a good AeT estimate.

    For your next test, let your heart rate get stable before you start the test and as RDK said, you can test at 160. I would recommend doing an Anaerobic Threshold test as well.
