- After more than 3,000 miles of testing, this watch still operates like it did on day one.
- Everyday usability and map features are brilliant in theory, but can feel sluggish and buggy in real life.
- The watch’s dense feature set, from advanced metrics and ECG to offline maps and a built-in flashlight, enables deep training optimization.
If the Garmin Forerunner 970 had existed when I started training for my first major biathlon, I might have set my sights higher than “don’t die, don’t drown, don’t c*** yourself because you didn’t fuel right.” That’s because it is easily the most ambitious multisport GPS watch Garmin’s ever released. It does everything: mapping, physiological metrics, recovery, safety, coaching, emergency alerts, and the gentle train shaming everyone feels from their Garmin.
I have now spent well over 3,000 miles running with this watch, and it still works and looks like it did right out of the package. This has become the watch I measure all others against. When I’m testing other watches, this one stays on one wrist, and I put the other watch on the opposite arm. It is the most predictable, reliable, feature-rich running watch I’ve ever tested. I use it for running, open-water swimming, weights, Hyrox, trails, nutrition, and period tracking.
The 970 arrives at a crossroads for performance wearables. Polar, Coros, and Suunto are breathing down Garmin’s neck with cheaper, sometimes nimbler tech. Yet for runners, triathletes, and other multisport enthusiasts who want the deepest feature set and the most accurate data, Garmin is still the leader of the pack. So, is the sticker shock worth it? And not for anything, is the learning curve worth it? To help you decide, I’ve sweat-tested the Forerunner 970 in training, racing, and daily life.

How I Tested
To get a true sense of the Garmin 970’s capabilities—not just in lab conditions, but in the variety of scenarios real athletes face—I used the watch as my sole training companion for over six weeks across multiple disciplines and locations.
I’ve logged hundreds of miles on city roads mapping marathon training routes, tempo intervals, and easy recovery days alike. To round out my mileage, I covered hundreds of miles on technical trails in the Adirondack and Catskill Mountains, putting the mapping and elevation features to the test on steep, rocky terrain and through dense forest where satellite reception often falters.
Beyond running, I wore the Forerunner 970 for open ocean swims along the notoriously rough New York City coastline and multiple sessions in standard-length pools—evaluating everything from waterproofing and wrist-based heart rate to lap auto-detection. The watch also tracked indoor gym sessions reliably: I logged hours of treadmill work, elliptical, and stairmaster intervals (I still hate them), relying on the multi-band GPS and motion sensors for accuracy even in signal-challenged environments.
To measure recovery, I did what any person with my training schedule would do—I hit the hay hard while wearing my Garmin 970, and spent a great deal of time becoming one with my cozy chair in the office, letting it measure my every metric. I also logged my period in the Garmin app, and it’s now set up to measure my skin temperature and heart rate to predict the next time my uterus demon is arriving.
Mapping and Navigation—Topographic Ambition, Real-World Quirks
Maps for Days, but Not Always in a Rush
The Forerunner 970 ships with full-color TopoActive maps and lets you route, re-route, and even share routes at the trailhead—a level of flexibility unmatched in the industry. Compared to other brands, the detail and on-watch editing options are best-in-class, especially with features like ClimbPro to break down elevation for climbs and descents—even the most intricate mountain courses feel transparent before you start.
But when it came time to actually use these tools, the real-world experience was sometimes less inspiring. Panning or zooming on large maps could cause noticeable lags of 5 to 15 seconds, and adding overlays like heat maps made it slower still. Occasionally, the screen would even timeout or glitch weirdly before a tile finished rendering—a problem I’ve never had with other Garmins, but have had with Suunto and Apple Watch models.
Still, the recalculation feature—auto-adjusting routes when you go off-course—mirrored the top-of-the-line Fenix and worked reliably during my tests. My natural sense of direction is decent, but I find that the audio and haptic cues are extremely helpful, especially when I space out on my run listening to an audiobook or podcast.
Training Metrics and Advanced Physiology—Pro Data, Not for Everyone
Do You Really Need VO2max, Running Economy, and ECG?
With the Forerunner 970, Garmin isn’t just tracking steps. You get every pro-level analytic the company offers: running economy, step speed loss, detailed training load and readiness, and new metrics for running tolerance and stride analysis. For triathletes and data fiends, this toolkit is unmatched, enabling precision training beyond what most daily runners will reasonably use. The only drawback is the UX of the actual app, which leaves something to be desired. I am sad to report that it still suffers from a poor layout and subpar inbuilt workouts.
Some features, though, are less remarkable in daily practice. Running economy and step speed loss require an external HRM chest strap purchase, and physiological estimates like VO2 max and REM sleep are still debated for their real-world utility—cool figures to have, but limited actionable value if you don’t know what they mean or how to interpret the data.
Garmin has some neat insights available for users when they click through their data, but I’m unsure how many casual runners are interested in these metrics. Had I not been simultaneously testing HRM devices, I likely would not have even brought the running economy and step speed loss data into my testing algorithm, but they are pretty neat to look at and potentially learn from over time.
As for the ECG feature, it’s mostly a manual, snapshot tool—can be a hassle to enable, and doesn’t give the kind of continuous health surveillance many users expect from the headline. However, as a runner with a benign (diagnosed) arrhythmia, I like the ability of taking these moments on days where my ticker is tapping a little more out of step. It also does a damn fine job of tracking your stress. For instance, while testing this watch I was struck by a helluva migraine that threw me sideways. It not only clocked my stress, but accounted for it in my suggested daily and weekly training schedule, helping me recover more quickly. It also noted the change in my temperature and heart rate in response to my PMS, and accurately predicted when my period was incoming.
As for the train shaming I mentioned above, the Garmin kept that right on rolling by telling me that I’m not sleeping enough, definitely running too many miles (you deal with my ADHD then, Garmin) and should probably cut back on my Hyrox work if I plan to keep my knees and my social life. Joke’s on Garmin, I’ve already accepted the fact that I have no social life.
That’s not to say there weren’t some serious surprises in store for me. The race predictor function was the biggest “what now?” metric moment in my testing, because my predicted times changed between my Venu testing and my 970 testing. The predicted finish times slowed down by minutes, which I found odd, until I looked at all of my training and health data and realized I had likely been sandbagging my workouts a bit, and not hitting my effort goals. The improved tracking of the 970 gave me insights I might have otherwise missed while consistently training in zone 2 runs instead of pushing some of my training miles faster.
Another function out of the box that's new to the 970 is the ability to preload a race into the watch and set it to auto lap by timing gates, which means it will automatically lap by using the mile or kilometer mile markers in the race, as opposed to just using the distance marker in the watch. I used this during a 10K, and found that it was a neat function for race day, but only necessary/fun if you’re collecting a serious number of bibs in a year for the races covered by this function.
Everyday Usability and Battery—Living With a “Pro” Watch
Endurance Battery, Clunky Everyday UI
With up to 26 hours of claimed GPS use and the new AMOLED screen (which is sharp and readable even at noon), the Forerunner 970 handles day-long ultra events easily. In my testing, real-world battery life clocked in a bit shorter, especially with Always-On Display and SatIQ enabled, but still easily outlasted a race day—more so than my Apple Watch Ultra.
What made daily use frustrating, though, was the sheer number of clicks and menu dives often required for non-standard tasks. Saving a workout can take 10 to 20 seconds, as does clocking reps when you’re in a free workout mode, and some interface quirks—like touchscreen sensitivity or the overwhelming menu layout—can make this feel more like a computer or smart phone than a watch.
There’s also the question of aesthetics: while I love the rose gold bevel around the watch, it’s still a huge face set on a rubber band in a blah color. It is however, so much lighter than its competitors like the Apple Watch Ultra, and a much lower profile, making it more comfortable to wear overall.
The Verdict
The Garmin Forerunner 970 is the watch par excellence for data-driven racers and endurance athletes who want to track, analyze, and optimize every aspect of performance—and who don’t mind paying for the privilege. If all you want is reliable GPS, HR, and simple metrics, you’ll find this wildly overbuilt, expensive, and occasionally irritating in daily use. Go for the 265 or 965 for a simpler, accurate monitor with less on-watch strategy required. But if you’re a triathlete, ultra runner, or metrics-obsessed optimist, there’s no more complete partner on the market right now.
Ideal use cases? Big race days, adventure courses, long-distance training blocks, and the kind of everyday logging that “pro” users find motivating. Everyone else: unless you’re really using the depth, Garmin’s mid-tier watches or competitors’ offerings are likely a better fit.
