Hello, I’ve been poking around with the 80/20 system now for a while. I always liked the concept of low intensity training, and after getting the book from Audible (in audiobook format, which is pretty cool) I wanted to take the plunge. I’ve gone through the 5k level 1 free plan (HR metric) and purchased the full version, along with the TP membership.
I’m one of these that have a really oddball heart rate. The MAF formula and the 220-age formula totally do not work for me. Although my resting rates hang around the upper 50s to low 60s. I’m 57, and regularly get into the mid 190s, and sometimes push beyond 200. Blessing or a curse, I’m not sure, but that’s what it is.
I took a 1 mile time trial of 8:51 to get my TP of 10:15. I ran at that pace to get a LTHR of 178. I plugged those numbers into the 8020 zone calculator to get my running zones. I do plan on doing the LTHR field test to confirm if I am either on the right track, or have been doing it wrong this whole time.
I look forward to learning more from this great program and group.July 7, 2021 at 12:22 pm #13140
I would assume your threshold pace and threshold HR are not correct as your test is not in line with the 80/20 recommendation. It will be interesting to see your field test results.

Ok, I did the 20 minute LT pace test. Averaged 9:16 min/mile, and entered into the calculator, and it came up with 9:48 min/mile LT pace. Quicker than what I was expecting.
Now for the 15 minute part for the LTHR do I go with the average HR for those 15 minutes?July 8, 2021 at 3:36 pm #13168David WardenKeymaster
D, take the peak 15-minute HR from that 20-minute test, which is almost certainly the last 15-minutes of the test. That is your LTHR.

Thank you David. The peak being the highest point of the last 15 minutes?July 9, 2021 at 8:22 am #13188
Peak 15min averageJuly 9, 2021 at 9:02 am #13189
Ok thanks. Believe it or not it’s 188July 12, 2021 at 10:44 am #13239
That seems rather high? Or is it 95%? Which would be 178.July 12, 2021 at 12:35 pm #13243
No, you dont use the 95% rule for HR.
Did you use a chest strap or is that wrist based? My experience is that wrist based isn’t the best choice…
What was your average pace for the 20min time trial? Why don’t you use pace? You should get both, heart rate and pace threshold with this test.

Yes, I did have a chest strap for the test. I’ve been using one for about 3 months now. I guess I just have a high HR. My pace ended up being 9:13 min/mile. Putting that into the calculator gave me a 9:42 min/mile LT pace.July 12, 2021 at 2:04 pm #13250
I’d recommend to use pace as your main metric and HR as your secondary metric (when running uphill for example).
My Power/HR/Pace lines up somewhat nicely as long as I run in similar conditions as the test was performed. What I want to say is, that I, for example, would see much higher HR in hot temperatures, but as I run by power, I don’t bother. A watt is a watt is a watt or so 🙂
Just my 2 cents.
