The Garmin Forerunner 970 is the working watch you purchase when you do not need any compromises. Largely that comes all the way down to new options like working tolerance, influence load, and projected race time, together with all of the coaching load instruments you realize 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 rely, and supporting information 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 normal step-counting app.
The top consequence? The Forerunner 970 is shockingly correct. It provides you dependable well being and health information from exercises, then spits out information from its algorithm that predicts your cardiovascular and biomechanical fatigue with stunning 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, comparability level. Chest straps are the gold commonplace, 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 monitor, then a tough monitor exercise. For the primary exercise, each units ended with a 145bpm common and 157bpm max, however I would count on related outcomes for such a brief run.
The chart reveals 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 word: 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 true robust check comes throughout anaerobic exercises; most health watches I’ve examined fall properly wanting 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 may 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 good points 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 brief for lengthy stretches and skewing the info. Even health watches just like the COROS PACE Professional and Polar Vantage M3 have issues with anaerobic information.
The Forerunner 970 did finish 1 bpm wanting the H10 strap for HR common, however all that issues to me is that I can rely 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 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. Curiously, the 970 confirmed my minimal, common, and most coronary heart fee as 1 bpm increased than COROS’s information.
These graphs are fairly properly 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 information.
In the end, I would say the Forerunner 970’s Elevate v5 sensor reveals a slight tendency to overestimate my coronary heart fee by about 1 bpm, however in any other case is as reliable as I would 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 can not normally 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 targeted 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 satisfactory, or if runners ought to keep on 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 a protracted distance.

The top consequence was ten miles of boringly correct GPS information, with Garmin (orange) typically nearer to my real-life place and COROS (blue) barely adrift however all the time 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 beneath foliage, too.

Once 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 chance 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 route and correcting each time 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 the right 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 joyful to know that I can rely on this mode, even when I normally choose 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 also 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 rely accuracy
Previous Garmin watches have achieved fairly properly for step rely accuracy. Once I wore six watches for six,000 steps, the Forerunner 265 did the very best, solely 15 steps off. Final yr, 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 check.
These outcomes are all fairly stable, 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 rely 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 sit down down on a bench and checked the full: 6,739 steps. Yep, 5,004 precisely.
I felt concurrently surprised on the accuracy and aggravated that folks in all probability would not imagine the consequence. So I stood again up and walked one other 5,000 steps as twilight fell into night to verify 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 can not assure you may get comparably actual outcomes; it might rely in your gait, or in the event you maintain a cellphone or trekking pole in your watch-side hand. However personally, I am thrilled figuring out that once I stroll 10,000 steps a day, the Forerunner 970 will monitor each step with out fail.
Garmin Forerunner 970: General accuracy
Smartwatch accuracy goes properly past the uncooked information. It is also about whether or not the Garmin Forerunner 970’s coaching information is each correct and useful.
On the core of Garmin’s Firstbeat Analytics information is your VO2 Max, lactate threshold, coaching load focus, and restoration time. These give attention to cardiovascular information, and whereas I can not 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 choose 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 information than the VO2 Max graph reveals. And it is solely obtainable on high-end fashions just like the 970 and Fenix 8.
Typically talking, the 970’s restoration time estimates have been fairly correct at judging short-term exhaustion and once 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 would 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 groups and joints differs out of your cardiovascular fatigue, however previous fashions could not monitor that.
How properly 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 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 all the time accurately judged the relative influence load — like recognizing {that a} blistering two-mile monitor exercise may trigger as a lot pressure as a standard four-mile run — throughout this previous month of coaching.
The one new characteristic that I discover somewhat suspect is the race predictor device (proven above) that guesses how briskly I am going to be capable of 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 appears 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 general health degree and the precise influence of every run. It is going to overwhelm somebody who is not ready to dive into menus to search out all of this information, however Garmin veterans will love the 970 merely for coaching load focus, weekly mileage tolerance, and the brighter show.
