Ha - great going larks - I can't get motivated on solo reps for hills to get to max. I'd have a chance if I was chasing somebody.

This was my 5k max effort run today. How would you calculate the heart rate zones from this?

Nice. Today's fake parkrun? Not , hopefully (channelling Glenn's suggestions above) being chased by any of Leicester's Covid-19 carriers.
If you went on WHR, and assuming resting HR of 49 (it makes the calculation easy ) then heart rate reserve (hrr) is 189 -49 = 140. Easy runs below 70% hrr ie 49 + (0.7*140) = 49 + 98 = 147 BPM; efforts above 85% hrr ie 49 + (0.85*140) = 49 + 119 = 168 BPM.
Easy can go down below of course: some people might prefer below 65% hrr ie 140 BPM. And efforts can be harder, it's not dipping below which matters.
That's as I understand it. And people who use zones based on max hr will be along with a different set of figures.
(If your resting hr is not 49, please adjust figures to suit.)

My resting heart rate is relatively high, about 65!

I'd get my Garmin to do it as posted a page or two ago.
You need a rest heart rate though.

Hmm. Has your rhr shifted with your training at all?
Revised figures then: below 152 (146@ 65%); above 171.

Just checking a couple of things :
Was that using a chest strap or optical ? Apologies if you've commented on what you used previously on the thread. Most will find that optical not accurate enough for a maxHR test.
Most find they can go to a slightly higher maxHR on a shorter test, especially hillreps as detailed by Gobi a few days ago, than at the end of a longer run. So you might be able to get a few beats higher than 189.

Would echo the chest strap comment above. Would have regularly recorded mid to high 190's and into the 200's via the watch. Yet to bother 185 with the chest strap.
