Where's Your Heart Rate?

If your heart rate is in zone 5 on an easy run, something's up.

Are you on Garmin checking out your run details and notice that some or all of your run was spent in zone 5? If so, something is up and you need to make some adjustments.

Yes, heat and humidity have a big part in why your heart rate is high. But having a run that is supposed to be easy and your heart rate is in zone 5 for the majority of the run is no good.

I don’t have all the answers to why your specific run might be way off-kilter, but these are a few reasons why it could be off:

So what are you to do?

Here are 4 things you can do right away to adjust your high heart rate:

  1. Continue to run early and avoid the hottest parts of the day. Also, know that being fatigued will start you out at an elevated heart rate, so make sure you are well-rested.

  2. Fix the watch you currently own. Make sure it’s snug on your wrist and tracking appropriately.

  3. Get a chest strap that pairs with your watch. I have one from Garmin and I really like it. I wear it on workout days and on some long runs days (mostly just for data). You can get a chest strap just like mine (affiliate).

  4. Go into Garmin (on a computer) and adjust your training zones to match your training intensities. It’s good to know your max, but if you don’t, there are articles published on the web that’ll help you.

Friday’s Action Plan:

Easy run in zone 5? Do something to make sure you are actually running an easy effort. Fix your training zones, get a HR strap, adjust your watch, and/or avoid the midday heat and humidity.
