The Garmin Forerunner 970 is the operating watch you purchase when you do not need any compromises. Largely that comes all the way down to new options like operating tolerance, influence load, and projected race time, together with all of the coaching load instruments you recognize and love. However you are additionally paying $750 for the absolute best accuracy.
So, how correct is the Garmin Forerunner 970 for GPS monitoring, coronary heart price, step depend, and supporting knowledge like coaching load? I put its Elevate v5 HR sensor, dual-band GPS, and different sensors to the check throughout weeks of actions, evaluating its outcomes in opposition to satellite tv for pc maps, chest and arm HR straps, and my typical step-counting app.
The top consequence? The Forerunner 970 is shockingly correct. It provides you dependable well being and health knowledge from exercises, then spits out knowledge from its algorithm that predicts your cardiovascular and biomechanical fatigue with shocking accuracy.
It sucks that the Forerunner 970 price ticket is so excessive, however Garmin makes a valiant effort at justifying it.
Garmin Forerunner 970: Coronary heart price accuracy
Throughout a number of runs, I used my Polar H10 chest strap and COROS HRM armband as management teams in opposition to the Forerunner 970. Optical armbands are extra constant and responsive than wrist-based optical sensors in my expertise, comparability level. Chest straps are the gold normal, however smartwatches at all times path behind them; your finest hope is for the outcomes to be shut.
First, I used the Forerunner 970 and Polar H10 on a brief jog to a observe, then a tough observe exercise. For the primary exercise, each gadgets ended with a 145bpm common and 157bpm max, however I would anticipate related outcomes for such a brief run.
The chart reveals that the Forerunner 970 responds quickly when my coronary heart price climbs, however is about 10 seconds slower to acknowledge falling coronary heart charges than the chest strap.
(Facet be aware: Polar tracks HR when an exercise is paused, however the exported graph reveals a flat line, weirdly. Simply ignore them; they do not have an effect on the outcomes.)
The actual powerful check comes throughout anaerobic exercises; most health watches I’ve examined fall nicely in need of my precise HR, solely coming near the chest strap on common as a result of they measure inaccurately excessive HRs throughout cooldowns. However the Forerunner 970 did even higher than I would hoped.
As you possibly can see, the Forerunner 970 was virtually at all times inside 1–2 bpm of the chest strap, solely struggling a bit to maintain up in the course of the fast HR good points after a pause.
For context, mainline watches just like the Galaxy Watch Extremely or Pixel Watch 3 wrestle mightily with anaerobic monitoring, falling 5–10 bpm quick for lengthy stretches and skewing the info. Even health watches just like the COROS PACE Professional and Polar Vantage M3 have issues with anaerobic knowledge.
The Forerunner 970 did finish 1 bpm in need of the H10 strap for HR common, however all that issues to me is that I can depend on the Forerunner 970 to be correct within the second once I take a look at my wrist mid-sprint and see my coronary heart price. That is surprisingly uncommon!
Subsequent, I ran with my Garmin Forerunner 970 and COROS PACE Professional synced to my COROS HRM strap throughout a ten-mile run. Apparently, the 970 confirmed my minimal, common, and most coronary heart price as 1 bpm greater than COROS’s knowledge.
These graphs are fairly nicely synced; Garmin simply detected that I used to be working barely tougher than COROS. The hole is so small that it would not have an effect on your coaching load knowledge.
Finally, I would say the Forerunner 970’s Elevate v5 sensor reveals a slight tendency to overestimate my coronary heart price by about 1 bpm, however in any other case is as reliable as I would hope for on this value vary. I do not really feel the necessity to put on an exterior HRM with the 970 for the perfect outcomes, one thing I am unable to normally say with most health watches.
Garmin Forerunner 970: GPS accuracy
Garmin watches with dual-band GPS virtually at all times carry out seamlessly in my exams. Since I knew the Forerunner 970 would match its siblings, I centered as a substitute on testing whether or not its default SatIQ mode — which sticks to GPS solely till it wants the opposite satellites to avoid wasting battery — was sufficient, or if runners ought to stick with dual-band GPS solely.
For my ten-mile run, I used “Greatest accuracy” on each my Forerunner 970 and COROS PACE Professional; each ended at 10.01 miles and confirmed a minuscule hole of six ft on the finish. It is superior to see each manufacturers be in such shut lockstep over an extended distance.

The top consequence was ten miles of boringly correct GPS knowledge, with Garmin (orange) typically nearer to my real-life place and COROS (blue) barely adrift however at all times parallel. I spotted after the run that I’ve the PACE Professional set to my left wrist however wore it on my proper, which can have skewed the tracked line a bit.
Checking particular factors like crosswalks, I might clearly see moments the place I modified my path to press the stroll button, or (within the first screenshot above) dithered about in a semi-circle whereas ready for the sign. My path stayed constant below foliage, too.

After I ran a half-marathon sporting Meta Ray-Bans earlier this month, I used to be additionally sporting the Forerunner 970 in SatIQ mode. I did not put on one other watch as a result of sporting a number of watches mid-race is a distraction, however it was a possibility to see how the 970 dealt with tall buildings or underpasses.
Because the screenshots above present, the watch did wrestle with underpasses a bit in SatIQ mode, guessing at my path and correcting each time it re-aquired my sign, and even displaying me operating backward at one level. However tall buildings did not appear to be a problem, with me by no means straying additional than the sidewalk.

On one other SatIQ-tracked run on a windy path, the Forerunner 970 stayed heading in the right direction regardless of sign blockage from bushes and the tall hill close by. Except for one or two tiny blips, I had no complaints in regards to the accuracy. It made me pleased to know that I can depend on this mode, even when I normally want dual-band GPS.
Once more, I used to be very pleased with the outcomes right here. Cheaper dual-band Garmin watches just like the Intuition 3 or Forerunner 265 may additionally suffice, however the Forerunner 970 lives as much as the standard I anticipated, and higher than different manufacturers providing multi-band GPS.
Garmin Forerunner 970: Step depend accuracy
Previous Garmin watches have achieved fairly nicely for step depend accuracy. After I wore six watches for six,000 steps, the Forerunner 265 did the perfect, solely 15 steps off. Final 12 months, the Forerunner 965 was 17 steps off after 5,000 steps, however some sensible rings did barely higher. The Garmin Fenix 8 was 50 steps off after 10,000 steps, and my colleague Derrek discovered that the Forerunner 570 was 40 steps off in his personal check.
These outcomes are all fairly stable, and Garmin watches are nice at avoiding false-positive steps in the course of the day. Nonetheless, the pricier fashions did not yield higher outcomes, and Garmin has by no means talked about upgrading its accelerometers or gyroscopes. I assumed the Forerunner 970 step depend accuracy could be comparable.
I began the check with 1,735 steps and walked for five,000 steps, holding my cellphone in my proper hand to trace them with a counting app whereas my left arm swung freely. At 5,000 steps, I took one other 4 steps to take a seat down on a bench and checked the full: 6,739 steps. Yep, 5,004 precisely.
I felt concurrently shocked on the accuracy and aggravated that folks in all probability would not consider the consequence. So I stood again up and walked one other 5,000 steps as twilight fell into night to examine if it was a fluke.
I checked my complete: 11,740 steps, aka one other 5,001. That makes the Forerunner 970 off by one step after 10,000.
I am unable to assure you may get comparably actual outcomes; it could rely in your gait, or should you maintain a cellphone or trekking pole in your watch-side hand. However personally, I am thrilled realizing that once I stroll 10,000 steps a day, the Forerunner 970 will observe each step with out fail.
Garmin Forerunner 970: General accuracy
Smartwatch accuracy goes nicely past the uncooked knowledge. It is also about whether or not the Garmin Forerunner 970’s coaching knowledge is each correct and useful.
On the core of Garmin’s Firstbeat Analytics knowledge is your VO2 Max, lactate threshold, coaching load focus, and restoration time. These concentrate on cardiovascular knowledge, and whereas I am unable to know if my VO2 Max is correct with out going to a lab, its rises and falls do correspond to real-life modifications in health — however slowly.
I personally want the Endurance Rating, which reveals my health developments throughout the previous few months that can translate into precise pace and longevity throughout runs, with extra actual knowledge than the VO2 Max graph reveals. And it is solely obtainable on high-end fashions just like the 970 and Fenix 8.
Usually talking, the 970’s restoration time estimates have been fairly correct at judging short-term exhaustion and once I’ll recuperate. And I completely love Garmin’s coaching load focus for serving to me decide when to do low cardio or anaerobic runs; the one draw back is how Garmin would not break up a run’s coaching impact into all three classes, tending to lump most of it into one slot.
The 970 builds on the cardiovascular basis of previous watches with operating tolerance and influence load. Your physique’s biomechanical pressure on muscle tissue and joints differs out of your cardiovascular fatigue, however previous fashions could not observe that.
How nicely do they work? I already wrote earlier this month about how helpful and correct operating tolerance is! The Forerunner 970 accurately judges when lengthy runs put an excessive amount of influence load on my physique previous its tolerance. I ignored the info the primary time and ended up hurting myself; now I am again on the cusp of my physique’s restrict, and I am being extra cautious.
After each run, it calculates the influence load primarily based on elements like your cadence, the elevation change, and depth. I’ve discovered that Garmin’s estimate has at all times accurately judged the relative influence load — like recognizing {that a} blistering two-mile observe exercise may trigger as a lot pressure as a traditional four-mile run — throughout this previous month of coaching.
The one new function that I discover a little bit suspect is the race predictor device (proven above) that guesses how briskly I will have the ability to run a race weeks from now at my present coaching tempo. Garmin’s race predictions have at all times been optimistic, however that half-marathon time looks like wishful pondering for me at my present degree.
In any other case, the Garmin Forerunner 970 provides me a complete and correct measure of my total health degree and the precise influence of every run. It’s going to overwhelm somebody who is not ready to dive into menus to search out all of this knowledge, however Garmin veterans will love the 970 merely for coaching load focus, weekly mileage tolerance, and the brighter show.
