It’s definitely a wrist HR issue! The bouncing and “uncontrolled” arm movement allows that more light comes in to the sensor. WHR is almost useless on the trails (/everywhere ;)).

Hi Johanna,
i think i can’t help you that much, or let the experts here write an answer. Just some stuff i noticed in my training.
I train with the UA approach since i’m “back” from my injury (Aug 19).
After several tries i found my zones (AeT = 161bpm, AnT = 171bpm, no ADS). For the first couple of weeks it was easy to run almost all my normal runs on top of Z1 (~145bpm, which is almost my MAF HR). I was even making sure i don’t let it drop in the downhills (which at a sub 3:30-40 km/pace is a bit suicidal). As my weekly volume raised i noticed that some strange nagging stuff in my illiopsoas came back. When i run at Z1 top almost all the time.
Since 3-4 weeks i just told myself it’s ok to spend the training duration anywhere in the Z1 range. In the downhills sometimes even a tat lower.
My conclusion (and what you observed), just some beats lower/less intensity on normal runs made a huge jump in the healing of my illiopsoas “problem”. I even ran my biggest millage week (263km, 13km vert) with fewer problems than my “normal” previous weeks (130km-150km). Last week i did a run right at AeT for 50 min. Where i saw and felt a huge difference from previous runs at this intensity. It was “easy” and faster.
What i try to say, don’t stick to hard on that numbers. As Scott says think about 5bpm buckets, we’re not machines. If the easier intensity feels better day to day and you maybe even can handle more volume -> i would go for it. Maybe you have that same “AHA” effect if you run your next hard workout.
Btw.: did you try the HR drift test on a treadmill, to get your AeT?
Still believing in your aerobic system ;)!
have a great week — mirko
@Kellert62, just a question how did you get those numbers out of Training Peaks. I can’t see my self created zones in the repports?
Hi Johanna,
i can’t download the PDF, maybe you need to re-upload it without the special chars in the document name.
If you really suffer from ADS (which i can’t belive, seeing what you do on strava) and the GAP between AnT and AeT is more than 10%. Then you should set top of Z2 to 130~ bpm and train below or at this value. Think u know this already.
Before i start to guess:
please fix the document link and ppl will help 🙂
have a great afternoon — mirko
Thx Scott’s!!
Yes it was indeed a great week! My biggest in a lifetime.
Anyway, thx for your answers, suggestions and clarification. I will apply it to my training immediately and see how this develops.

Just my 5 cents. This week my HR chest strap died somehow. I own a brand new Garmin Fenix 6x. I did some runs with only the wrist HR on the same terrain i always train. The readings from WHR in 2020 are as bad as they where when i got my first watch with WHR.
Just buy a chest strap :)!
Just for clarification, you don’t use a wrist heart rate monitor to check?
In my case I can’t breathe trough my nose, when I’m going close to the top of my Z2. I think genetics plays a big role here.
Hi Blake,
Indoor DIY Guide to Determining Your Aerobic Threshold: Treadmill Test
Here they write 10%
It’s not for lab testing but i think make sense too.
Hey Alison, nice to hear from you here 🙂 (i think i wrote with you about the Strava club)
I can push pretty good in the downs but to be honest, i never tried how high it will rise if i give it “all out”. I hear from peoples that I’m a goat in the downhills. They feel easy for me. So i think we have a similar DH approach for training them.
Thanks so much for your answer too!
Thx Scott for clarifying this! This makes sense to me. Do you think you can wreck your training by going just by HR? For me it’s a welcome reflection of how hard i worked. My AeT/AnT spread is only about 10beats.
Hi Scott this was fast!
I’m training my downhill technique pretty often. In form of pickups, or if i’m feeling good just hammering down a longer trail section. Downhills shouldn’t be a weakness of mine at this point, i love them too ;)! But if i run in Z3 on a runnable not too techy and steep downhill of ca. 11-15% this would be a pace around 2:20-3/km
I would do them on one long continuous hill, going up for the work period, and then trotting down for the recovery interval.
This makes completely sense and is not a problem in my area. Maybe i will try to include some flat sections to get some speed back there too.
Where do you see lack of precision when doing them outside?
Thanks
Hi Zac,
where did you find the guideline how to scale this plan?
just found it:
For single day events calculate the total vertical gain and loss as well as the distance of your target event.
For multi day event run in stages, with rest between stages, calculate the biggest single stage's gain/loss and distance.
For multiday continuous, mega long, events like the Tor des Geant or Tor des Glacier use the biggest single day you expect to encounter.
You will use these numbers to progress your training load over the course of the program.
For events from 100km to over 100miles in length with over 5000m in total elevation this week should contain about 50%(for 100miles) up to 60%(for 100km) of the event's vertical and distance in your targeted event.
For events around 50miles to 100km in length and around 3-5000m in elevation this week should contain about 60-70% of the event's vertical and distance.
For events around 50km and shorter in length with about 3000m in elevation, this week should contain about 80% of the event's total elevation and distance.
Thanks in advance — mirko
Read it too in my opinion a good one 🙂
Thanks Terry and Scott!
The Lunch runs differs a bit but mostly they’re mid Z1, or Recovery style runs. If i feel good. I do some strides/pickups towards the end.
Anyway merci for your opinion!
have a grat day — mirko
Hi thrlskr,
maybe this is false precision. I had similar HR curves in the past. Sometimes the sensors are not “wet” enough at the beginning. Then you start to sweat and the HR chest strap gives accurate signals.
I bought a newer chest strap and those strange initial HR drifts are gone since then.
Not sure but maybe that’s all.
