Zone 5 Adjusted - Lower Compared to other people

Juan
over 1 year ago

Hi, Everyone

I am quite new here, I just have a quick question about Garmin, I can see that it keeps lowering down my zone 5 based on my daily activities.

Now, my zone 5 is at >167BPM, for context, I am 30 years old, male. 173cm, 29Kg, I run 6x a week and is preparing for a sub4 hour marathon.

I hope to hear your insights whether it is good or bad?

Thank you

    Heart rate is not comparable between people. It can vary a lot. Your zones are probably based on max HR, which the watch can estimate based on your workouts, Yours is most likely 186, which is normal for your age.

    Hi, first of all if you have a new watch consider it needs some running sessions in different condition/effort levels to estimate your hr zones/vo2 max, and a chest strap can help for lactate threshold (LT) test and better accuracy during sprint/intense sessions. I assume that if you're running 6x week you know the effect of zone 2 and LT runs on your body. If you have a chest strap, could be useful to set the hr zones based on %LT and run a couple test (not the same day), and see if the result suits more your performance, like the pace of your zone 2 or zone 4 knowing your 10k PB.

    As, said , every hr is on our own, but you can have an idea of how does training affect your hr usually. If you try a lactate threshold test the result is usually the upper limit of zone 4, and you can train that, or take into consideration the max pace you can run a 10k race.

    I'm around your age, my LT and get higher with training, but that's also based on what you're training, if it's zone 2 you may be lacking z4 or vo2 max but that's ok, if it's not your actual goal.

    Secondly, 29kg ..?.

    Thank you both @ovekvam @ben for the inputs, I meant 69kg***, that's a typo. 

    I usually train zone 2-3, 4x a week with LSDs on Sundays, and speed intervals 2x a week. I will try and buy the chest strap

    Hi Juan,

    try to reset your HR zones (for a run) once a week. Garmin calculates your max HR based on your condition and it can vary. Somehow Garmin doesn't do it right. Manually resetting helps.

    And yes, %LTHR based zones are better, but you need a chest strap to get your value, as mentioned above..
