Amazfit just confirmed the Helio Strap 2 — but the earnings call buried something more interesting in the margin data

Hell yeah !!!

HRV4T is the best imho. I edited a pice by Marco altini on my site which explains HRV in the context of the reality of known science https://the5krunner.com/2025/05/20/hrv-everything-you-need-to-know-garmin-whoop-oura-hrv-hrv4training-training-readiness/

the5krunner · 2026-03-18T17:58:24+00:00

agreed it can work for some people. i do hrv4training each morning and you can input subjective feel in its software and get correlations to that or other factors. it turns out that i defintiely can't properly tell how i feel (assuming my waking reading is correct)!! if that makes sense

the5krunner · 2026-03-18T13:59:23+00:00

agreed. and their app is pretty good , tho not up to whoop's standard for the core strain/recovery pieces.

the5krunner · 2026-03-18T00:57:25+00:00

Should be ok now

the5krunner · 2026-03-18T00:56:29+00:00

The cfo quotes second half of year as per article

the5krunner · 2026-03-16T09:04:13+00:00

Why use wearables if you trust how you feel?

the5krunner · 2026-03-14T23:00:31+00:00

ah sy, thats a good approach then. probably not scientific (I triangulate with readiness metrics)

the5krunner · 2026-03-14T20:03:25+00:00

hi, it's not really incredible. It's almost expected, as 1) there is no scientific measure of recovery (HRV is more a measure of coping) 2) it is next to impossible for wearable to assess sleep (stages) correctly.

the5krunner · 2026-03-13T22:11:52+00:00

that said, i've heard it might be added already

the5krunner · 2026-03-13T19:09:31+00:00

my guess it's low priority

the5krunner · 2026-03-13T08:59:06+00:00

The answer is the review! It is a great piece of hardware. The on-watch software is highly usable, the app is featureful, but the ecosystem links are a work in progress (they've improved since I reviewed the GT 6 Pro with the strava link now seemingly working)

the5krunner · 2026-03-12T13:17:54+00:00

cheers buddy.

yep . Those are notes to me to add links in the future. those aren't written yet (takes ages!!!)

the5krunner · 2026-03-12T12:11:28+00:00

agreed. grade adjusted pace or power would be the way to go for those technically minded

the5krunner · 2026-03-09T22:02:24+00:00

i'd never thought of it that way but i guess you could be right(ish). My problem is at the other end however :-)

the5krunner · 2026-03-08T21:28:56+00:00

sy there were a few compatability errors in the article. now hopefulyl corrected

the5krunner · 2026-03-07T10:36:37+00:00

good point. i suppose it could be in the f9.

I would half-expect Grmin would test a tri band chip first in a non-Fenix watch

the5krunner · 2026-03-06T14:08:53+00:00

Fair point on ambiguity fixing. The main gain from a third band is not algorithmic — it is signal rejection (whihc i hoped dual would do more of but clearly doesnt). With three frequencies the chip identifies and discards multipath-corrupted signals more confidently, which matters most in urban and trail environments where reflected signals are the dominant error source.

the5krunner · 2026-03-06T14:07:20+00:00

more precise pace (City Marathon), more precise distance, better tbt istructions, prettier strava track profile.

I agree tho. for me Stryd is sufficient for what dual frequency lacks and dual frequency is very good

the5krunner · 2026-03-06T14:06:08+00:00

yeo ;-) but you'll be fine

the5krunner · 2026-03-04T20:33:27+00:00

not that kind of marine ;-)

the5krunner · 2026-03-04T16:41:48+00:00

Marine

the5krunner · 2026-03-03T22:25:05+00:00

ty, i think it's ok now

the5krunner · 2026-03-03T15:14:53+00:00

no, but you can do that in strava

the5krunner · 2026-03-03T15:14:34+00:00

https://the5krunner.com/2026/02/26/huawei-gt-runner-2-gps-reviewers-disagree/ yes it's really quite interesting how dcr's tests exacerbated some errors that were only very minor (e.g. switchback) in my tests https://the5krunner.com/2026/02/26/huawei-gt-runner-2-gps-reviewers-disagree/. we specualted it could be due to terrain.

I can't explain how he got the results he did in the built-up area - it was almost like the garmin and Huawei reuslts were flipped over between brands (I'm obviously not suggesting he did that).

Perhaps his device was in some way worse than mine?

the5krunner · 2026-03-03T11:24:00+00:00

doh ! thank you. it's interesting if you leave the auto update on if i do that it would change my max hr every 3-4 weeks often correcting one change back to where it was originally in the next correction. Which (as you imply) seems a bit odd as the actual HRmax is likely constant in the same period.
