Our Verdict

For athletes who frequent trails or areas outside of cell range and want excellent tracking accuracy, the Garmin Forerunner 965 is an incredibly useful fitness tracker and is our top pick for athletes of any sport. With excellent battery life and a navigation feature, it can also help you get back home at the end of the workout or adventure. This watch was a favorite of our lead tester and offers unique features, but it is also one of the most expensive fitness trackers we have ever used. If you are looking for a device that integrates into your lifestyle and provides functions such as diet tracking, the Forerunner is probably not for you, but if you seek to explore your limits and want real-time monitoring and feedback on your performance, even on steep trails above treeline, then the Forerunner was made to be your companion.

Our Analysis and Test Results

The Garmin brand is highly respected in the running, cycling, aviation, marine, and automotive industries. The Forerunner 965 distinguishes itself from other trackers in our lineup with its GPS accuracy and robust data analysis. It may cast a shadow bigger than most people's wrists, but after we completed our testing for fitness trackers, it is the one device our lead tester continues to wear every day and use in her training.

Performance Comparison



The Garmin Forerunner 965 is the best fitness tracker we have ever used for serious training. It might also be the thing that helps you become an even better athlete, just as it did for us.

Fitness Impact


The Forerunner 965 is a super-charged training buddy that will track every mile and vertical foot gained (or lost) and record your heart rate with superb accuracy. Like a good buddy, it will also give you suggestions regarding pacing or effort during an activity. However, the auto-detection function doesn't work well for training or exercise, so you have to hit “start” to take advantage of the rich features.


GPS


The Forerunner 965 has a built-in antenna that works with satellite navigation systems in the U.S. (GPS), Europe (Galileo), and Russia (GLONASS). When you start an activity, like a run, the device takes a moment to find at least four global positioning satellites and establish location before notifying you that tracking is ready.

Elevation


With an internal barometric altimeter, the Forerunner 965 determines elevation gain and loss from direct measurements (most other trackers determine elevation from a connected smartphone and calculate it from the digital map). Just like the GPS function, the altimeter is highly accurate.

Credit: Genaveve Bradshaw

Some of us on the test team have long wished for a way to automatically track laps on an indoor climbing wall. It suffices to say that with the Forerunner, we can focus on pulling down while the tracker does the work of logging our total ascent.

Note that when tracking elevation in the “indoor climbing” activity, the altimeter initiates tracking after it detects an elevation change, so there is a brief delay before it starts to track a separate route, or lap, on a wall. When we accounted for the vertical height required for tracking to start (about 5 ft), we confirmed that the Forerunner had indeed accurately recorded our vertical ascent. Thank you, Garmin!

Distance Precision


The Garmin had an error rate of 0.33% in our distance tests. It was always spot on when cross-checked with known distances on hiking, running, and biking routes. This accuracy is beneficial when monitoring pace on runs, and it is highly responsive, so anytime we were trying to hit or maintain a specific pace in our training, it could tell us exactly how fast we were running at that moment.

The Forerunner tracks workouts with a GPS, but we also tested its ability to keep track of steps via the internal gyroscope and accelerometer.

Walking and Step Score


The Forerunner measures step count throughout the day, like most fitness trackers. We revealed an error rate of 0.58% in our successive test trials.

"This was my favorite tracker to bike with," commented our lead tester, “because the screen is so big and bright, meaning that I could pedal while glancing down to see my time and HR zone.”

Cycling Tracking


During our rides with the Forerunner, we could see duration, distance, total ascent, elevation, heart rate, heart rate zone, and lap time. There is also a function for measuring power output (although you need a Garmin power meter). Afterward, we could view a map of our route, average and max speeds, average and max heart rate, elevation gain and loss, time spent in each heart rate zone, and the cumulative training effect.

We truly appreciate how the Forerunner can track a myriad of activities that range from isometric to interval training.
Credit: Matt Lighthart

Workout Tracking


The Forerunner is also superb at tracking a variety of workouts. We particularly like the fact that we can easily navigate through multiple screens during an activity and access all controls directly through the device. There are also many workouts available directly on the device, and it indicates when the running pace is above or below a specified range. It also differentiates between active and rest periods. In addition, our lead tester loved that the Forerunner includes visuals for some of the workouts, like yoga or pilates.

Activity Tracking


Most of the trackers we tested offer a variety of activities that can be measured, but the Forerunner distinguishes itself from othera because it tracks activities with more nuance. For example, in running workouts, you can get a score for Hills, Running Dynamics, Vertical Oscillation, Stride Length, Running Power, and Performance Condition. Also, for a swimming workout, you can set the pool size and stroke style to generate data on strokes, length, swim speed, and laps. Furthermore, after testing it on a treadmill, an option popped up to calibrate it, which further improved the accuracy.

We loved the ability to set custom fitness goals on the Garmin app, such as a running event, and take advantage of training plans and guidance.

Community


There are extensive options for connecting with other athletes, friends, and family via the Connections tab in the app. The LiveTrack feature is something we like; you can automatically share activities with others and include a real-time map of your location (note that this feature requires that you carry a connected smartphone with you). We have experienced firsthand the benefits of setting goals and pursuing challenges, so we were delighted to see that Garmin includes these features in the app. Also featured are Expeditions that inspire you to accumulate the equivalent elevation of different peaks or treks via steps or mileage.

Health Impact


The Forerunner hits it way out of the park for fitness and health features, except diet tracking. If you need a tracker that can help you track calories and estimate caloric consumption, you'll want to look elsewhere.

Heart Rate


Heart rate accuracy is excellent, although we did relearn the importance of software updates when we experienced wonky heart rate readings two weeks into our test period (suffice to say, the update resolved the issue). Our lead tester stressed the value of the color-coded heart rate zone ring on the Garmin: “It's huge, bright, and all you have to do is glance down at your tracker to check in with where you're at while in the middle of an activity.” The heart rate sensor is also highly responsive to spikes and dips during HIIT workouts. It didn't miss a beat!

Diet


Diet tracking is where we feel the Forerunner is lacking. We could record water intake, but otherwise the options are minimal. “It doesn't seem like diet tracking is meant to be part of the Garmin fitness system,” reported our lead tester.

We highly appreciated the nap mode function, which silences notifications and sets a timer. (We called this “product research” whenever we stole a quick nap at the office).

Sleep Tracking


Sleep tracking performance with the Forerunner is excellent. “I've been blown away by the consistency of this tracker,” reported our lead tester. It did not fail to track every night of sleep and seamlessly uploaded the data to the app. After each night, we could access a report that included restless moments, resting heart rate, body battery charge (a unique Garmin score), average respiration, average heart rate, sleep stages, and more. The only downsides in sleep tracking are a slight inconsistency with autodetecting naps and the fact that sleeping with the Forerunner is a bit like spooning a small sundial.

Additional Health Indicators


Thanks to a suite of sensors for monitoring biometrics such as heart rate, blood oxygen, skin temperature, and ambient light, the Forerunner provides a wealth of health data and health impact scores such as training readiness, heart rate variability, stress, sleep quality, and others. According to our lead tester, the tracking on the Forerunner and the app “are very data-driven. No frills. No fluff articles or clickbait. Just full data with clean graphs and convenient color coding. It is easy to understand and gets straight to the point.”

Ease of Use


By the end of our testing period, the Forerunner had more mileage on it than most trackers see in a year. It still performed beautifully, but just as importantly, we still found it frictionless to navigate the menus or to finger-dance through the app. We mean it when we say that this tracker became like a trusted companion. The only time we had conflict was when we needed to put on a jacket or shirt with tight sleeves.


You can access all of your training and health data directly from the Forerunner, along with a host of sensors, such as the barometric altimeter and a compass.

Getting Started


Getting the watch and app set up is straightforward, and Garmin walks you through the process with clear information. You get data on steps, heart rate, and sleep after one day. However, it takes one week to three weeks to collect enough data to generate various scores related to training load, status, and heart rate variability.

The Garmin Connect app was designed with simplicity while offering a tremendous amount of data and analysis of your health and fitness metrics.

Phone App


We read some reviews that users feel the Garmin Connect app is outdated; however, we liked the accessibility of our data on the app. It might be a little simplistic in the formatting, but we never had an issue with auto-uploads, and our lead tester shared that “customizing it didn't require any extra time spent reading the instructions or trying to figure out what the terminology meant.” There are additional Garmin apps, such as Garmin IQ, for downloading different watch faces or other features.

The only major disadvantage we could find is that the Forerunner likes to pick fights with any sleeves, cuffs, or backpacks that come near it. One of our testers switched from wearing his watch on his left hand to his right hand just to make nice. Ultimately, he wasn't turned off by the experience; he chose to buy a Garmin for himself.

Wearability


Not for the faint of wrist, the Forerunner has a commanding presence. We are willing, however, to put up with the inconvenience for the device's capability. Some may feel differently!

The Forerunner may have an outsized presence, but it wasn't the heaviest tracker in our lineup. In fact, its weight seems appropriate for the level of technological sophistication.

Display


We've mentioned that the Forerunner is a bit like a tank, but “it makes up for its clunkiness by having such a crisp, gorgeous display,” reflected our lead tester after logging another marathon day of traversing peaks in the local mountains. The five tactile buttons for accessing functions are complimented by the touch screen for selecting items. There are a ton of ways to customize the tracker and to set it up just the way you want it. We did scratch the display during our testing, and although that didn't affect the function at all, we wondered what the display would look like after a year of training and adventuring!

Connectivity


The Forerunner paired quickly with our iPhone and Android test phones. It is more functional with Android phones (you can respond to texts with a tiny keyboard and view text photos), but otherwise, it seamlessly connects with Strava and auto-uploads activities. You can also control music and access a mobile wallet.

Subscriptions


We LOVE that the Forerunner offers so much overall function and doesn't require a subscription. However, some third-party apps or watch faces that can be installed via the Garmin IQ app have a paywall.

Water Resistance


The Forerunner is rated to five atmospheres and is made for swimmers, surfers, and the like. Water exposure didn't toggle any features by accident or stop tracking (something that happened with some of the trackers in our lineup).

Battery


The battery life on this tracker is so impressive,” reported our lead tester. “Despite constant usage, it tends to outlast all of the trackers in the lineup.” Honestly, how does the Forerunner do it? It stays alive for days on end while recording a wealth of data, all while rocking industry-leading GPS accuracy. The Forerunner may be expensive, but it has staying power.

Although the Forerunner isn't a speedy charger, we found that a brief charge of 15 minutes is all it took to boost it to a level that would allow us to log one more run before calling it a day.
Credit: Genaveve Bradshaw

It can be a bit annoying at charging time, however, due to the delicate connection between the cord and the four-pin port. It isn't a dealbreaker, but the cord can easily be knocked loose. In terms of the time needed to get back to 100%, the Garmin is near the middle of the pack. However, for the battery life it offers, a sub-two-hour charging time seems pretty good to us.

Fit


The Forerunner 965 is available in three colors but only one size. Our lead tester has small wrists, but the Forerunner doesn't play favorites–it makes a statement no matter who is wearing it.


That being said, the band was like a good workout partner and didn't get cranky in the heat or give up when things got sweaty. Our lead tester was used to the weight of the tracker after three consecutive days, and after nearly three weeks, she reported that “it feels natural and comfortable.”

We acknowledge that you have to train yourself to get used to the Forerunner for sleep tracking. The bulk became worth it when we realized we were walking around with as much sleep data as a university research department.

The Forerunner 965 is an incredible piece of wrist-born technology for serious athletes.

Should You Buy the Garmin Forerunner 965?


If you are serious about training and have witnessed how transformative fitness data can be for races or athletic events, you'll want to consider what the Forerunner can do for you. For those more interested in just sleep data and monitoring general activity, the Forerunner is probably more device than you need, and it won't be worth the weight or the expense.

What Other Fitness Trackers Should You Consider?


While we appreciate what a tracker like the Forerunner 965 can do, we also think that there are some great trackers out there that offer a lot of value while also being more svelte. In fact, the Garmin Vivoactive 5 is an excellent fitness tracker with similar features as the Forerunner, but at a much lower price. We also recommend the Apple Watch 9 as a superb fitness tracker that also happens to be a smartwatch and is a great choice for anyone in the Apple universe.
