The Garmin Forerunner 970 is the working watch you purchase when you do not need any compromises. Largely that comes right down to new options like working tolerance, influence load, and projected race time, together with all of the coaching load instruments you understand and love. However you are additionally paying $750 for the very best accuracy.
So, how correct is the Garmin Forerunner 970 for GPS monitoring, coronary heart fee, step depend, and supporting knowledge like coaching load? I put its Elevate v5 HR sensor, dual-band GPS, and different sensors to the take a look at throughout weeks of actions, evaluating its outcomes in opposition to satellite tv for pc maps, chest and arm HR straps, and my regular step-counting app.
The top end result? 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 fee 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, a great comparability level. Chest straps are the gold customary, however smartwatches all the time 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 units ended with a 145bpm common and 157bpm max, however I might anticipate comparable outcomes for such a brief run.
The chart exhibits that the Forerunner 970 responds quickly when my coronary heart fee climbs, however is about 10 seconds slower to acknowledge falling coronary heart charges than the chest strap.
(Aspect notice: Polar tracks HR when an exercise is paused, however the exported graph exhibits a flat line, weirdly. Simply ignore them; they do not have an effect on the outcomes.)
The true robust take a look at comes throughout anaerobic exercises; most health watches I’ve examined fall effectively 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 might hoped.
As you possibly can see, the Forerunner 970 was nearly all the time inside 1–2 bpm of the chest strap, solely struggling a bit to maintain up throughout the fast HR beneficial properties after a pause.
For context, mainline watches just like the Galaxy Watch Extremely or Pixel Watch 3 battle mightily with anaerobic monitoring, falling 5–10 bpm quick for lengthy stretches and skewing the information. 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 after I take a look at my wrist mid-sprint and see my coronary heart fee. 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 fee as 1 bpm greater than COROS’s knowledge.
These graphs are fairly effectively 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.
In the end, I might say the Forerunner 970’s Elevate v5 sensor exhibits a slight tendency to overestimate my coronary heart fee by about 1 bpm, however in any other case is as reliable as I might hope for on this worth vary. I do not really feel the necessity to put on an exterior HRM with the 970 for the very best outcomes, one thing I am unable to often say with most health watches.
Garmin Forerunner 970: GPS accuracy
Garmin watches with dual-band GPS nearly all the time carry out seamlessly in my assessments. Since I knew the Forerunner 970 would match its siblings, I centered as an alternative on testing whether or not its default SatIQ mode — which sticks to GPS solely till it wants the opposite satellites to save lots of battery — was sufficient, or if runners ought to persist with dual-band GPS solely.
For my ten-mile run, I used “Finest 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 a protracted distance.

The top end result was ten miles of boringly correct GPS knowledge, with Garmin (orange) typically nearer to my real-life place and COROS (blue) barely adrift however all the time parallel. I noticed 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 underneath foliage, too.

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

On one other SatIQ-tracked run on a windy path, the Forerunner 970 stayed on track regardless of sign blockage from bushes and the tall hill close by. Other than one or two tiny blips, I had no complaints concerning the accuracy. It made me blissful to know that I can depend on this mode, even when I often desire dual-band GPS.
Once more, I used to be very proud of 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 completed fairly effectively for step depend accuracy. After I wore six watches for six,000 steps, the Forerunner 265 did the very best, solely 15 steps off. Final 12 months, the Forerunner 965 was 17 steps off after 5,000 steps, however some good 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 take a look at.
These outcomes are all fairly strong, and Garmin watches are nice at avoiding false-positive steps throughout the day. Nevertheless, 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 can be comparable.
I began the take a look at with 1,735 steps and walked for five,000 steps, holding my telephone 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 whole: 6,739 steps. Yep, 5,004 precisely.
I felt concurrently surprised on the accuracy and aggravated that individuals most likely would not consider the end result. 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 whole: 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 will get comparably precise outcomes; it might rely in your gait, or if you happen to maintain a telephone or trekking pole in your watch-side hand. However personally, I am thrilled figuring out that after I stroll 10,000 steps a day, the Forerunner 970 will observe each step with out fail.
Garmin Forerunner 970: Total accuracy
Smartwatch accuracy goes effectively 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 deal with 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 desire the Endurance Rating, which exhibits my health traits throughout the previous few months that may translate into precise velocity and longevity throughout runs, with extra precise knowledge than the VO2 Max graph exhibits. 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 after I’ll get better. And I completely love Garmin’s coaching load focus for serving to me choose when to do low cardio or anaerobic runs; the one draw back is how Garmin does not cut 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 working 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 effectively do they work? I already wrote earlier this month about how helpful and correct working 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 information 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 based mostly on elements like your cadence, the elevation change, and depth. I’ve discovered that Garmin’s estimate has all the time accurately judged the relative influence load — like recognizing {that a} blistering two-mile observe exercise would possibly trigger as a lot pressure as a traditional four-mile run — throughout this previous month of coaching.
The one new function that I discover somewhat suspect is the race predictor device (proven above) that guesses how briskly I will be capable to run a race weeks from now at my present coaching tempo. Garmin’s race predictions have all the time been optimistic, however that half-marathon time seems like wishful pondering for me at my present stage.
In any other case, the Garmin Forerunner 970 provides me a complete and correct measure of my general health stage and the particular influence of every run. It is going to overwhelm somebody who is not ready to dive into menus to seek out all of this knowledge, however Garmin veterans will love the 970 merely for coaching load focus, weekly mileage tolerance, and the brighter show.
