Hello,
I am relatively new to running and just completed my first half marathon. I finished in 2 hours and 3 minutes. I am trying to adjust my workouts and develop a new heart rate zone chart to follow. I am 51-years old which gives me a 100% heart rate of 169. Using this as a guide I developed the following chart:
Zone 1 75-80% = 127-135
Zone 2 81-89% = 137-150
Zone 3 96-100% = 162-169
Zone 4 102-105% = 172-177
Zone 5 106+ = 179+
Does this look correct or have I miscalculated the rates? I would really appreciate some expert opinions on this.
Thanks.
It might be correct for you, or it might not be. The need to find your own zones.
That 220-age formula isn't right for a lot of people. I'm 47. The formula says my max heart rate is 173. Yet during hard interval workouts in the heat, for example, I've gotten my heart rate up to 198 (confirmed by wrist watch, chest strap and manual count).
Therefore, all those formula-based zones are wrong for me.
I go by this: I know when I run very easy, very slow, I'm going to be in the high 130's-140's. When I do a moderately hard workout, I'll be in the 150's-160's. If its a very hard workout, I might average 170's (180s for the intense portions). In an all out sprint, for way too long, I might hit 190's very briefly (which I don't do often, because it feels terrible).
I've always run a higher heart rate for age, for some reason. I'm not sure the reason. But it's normal for me.
