When HR and power zones don’t match

    I’ve been training for a while using HR, and have recently added power into the training equation. I’ve noticed that sometimes hitting the power goal means that I am going over on the HR side. Is that something I should be thinking about?

    For example, after doing some intervals, i go down to zone 1 power, but my heart rate never gets back down to zone 1.

    Jason, this delta between HR and Power is resolved by capturing both thresholds at the same time during your next threshold test. When HR and FTP are tested separately, they often will not align. By testing them at the same time, they must align, as the threshold point is being captured from the same effort.

    David,

    Just to add to the above question.

    When I did my threshold test I did it at a track but most of my runs are on quite a hilly undulating course.

    Is it recommended to do a test on the same area as you train or just suck it up.

    Regards,

    Alan,

    Great observation. Ideally, threshold testing is performed is an environment similar to where the majority of your training will take place. For example, those who need to train indoors all winter often have indoor and outdoor thresholds, as indoor training tends to lower HR and even FTP.

    This is ideal, but not always possible. In your case, this would be an exception where HR is superior to Pace. Hills are pace-killers, but HR would be more reliable in hills.

    However, hills is where Power again demonstrates it is the best intensity measure.

    Thanks David,

    I was doing HR and moved to Pace. I just got so tired of my watch nagging me I wasn’t in HR zone when running down hills. I much prefer to run up hills using pace and while I might not hit my pace zones running up I make up running down and I’m happy if the average is in zone. At the end I find my HR and paces zones are pretty much in the correct zone for the correct length of time.
    I do my speed repeat type runs mostly around the grass or paths of the local football fields. It’s mainly the Foundations, Recovery, Long Runs and Fast finishes I run on the hilly roads.

    Regards,
    Alan

    Can you elaborate how you would do that?

    I can usually control the HR by altering my cadence, but after heard efforts I don’t get back down.

    Jason, I’m not sure if your follow-up question is directed to me or Alan. Can you clarify what you are looking to elaborate on.
