I used the Garmin Epix Pro Gen 2 for two years on the track, treadmill, forest trails and mountain hikes. Its AMOLED display and flashlight impressed me, but its heart rate, running power, navigation and real-world battery life did not earn the level of trust I expected from a premium watch.
This review presents the actual numbers from my comparisons and separates them from Garmin’s specifications. It is a long-term test of one watch, not a laboratory study: settings, fit, conditions and individual use all affect the result.

Garmin Epix Pro Gen 2 after two years: the short verdict
- Best qualities: a highly legible AMOLED display, excellent outdoor distance results in my tests, maps, Garmin Pay and a genuinely useful LED flashlight.
- Main drawbacks in my use: a poor treadmill result, heart-rate and power discrepancies, unconvincing on-watch rerouting and short battery life with my settings.
- Best for: someone who wants a great display, maps and extensive outdoor features, and is willing to verify key training data with external sensors.
- My verdict: I like the watch, but at a premium price I cannot call it an automatic recommendation.
How I tested the Garmin Epix Pro Gen 2
I used the watch for two years while running on an athletics track, a treadmill and trails, as well as during mountain hikes. I compared selected results with a Garmin Fenix 6, a Stryd footpod and a chest-strap heart-rate monitor. Individual comparisons show what happened in a specific session; they do not replace a repeatable laboratory protocol.
I focused on practical questions: can I trust the distance, can I train by heart rate and power, does navigation help away from a known route, and how often do I actually need the charger?
Distance accuracy: track, treadmill and trail
Athletics track
Over a measured 5,210 m, the Epix displayed exactly 5,210 m. The Fenix 6 reported 5,280 m. In this session the Epix performed exceptionally well, and its trace followed the bends cleanly.
Treadmill
The treadmill result was the opposite. After 5 km, the Epix reported 5.5 km — a 10% overestimate. A watch estimates indoor distance from wrist movement and its learned stride, so calibration, pace and arm swing matter. In my test, the error was too large to use without correction.
Trail running
Off road, the Epix measured 18.27 km while the Fenix 6 and Stryd combination measured 18.30 km. A 30 m difference over that distance is an excellent result. This session supports outdoor distance tracking as one of the watch’s strengths.
Wrist-based heart rate
In the run shown below, the Epix reported an average of 145 bpm and a maximum of 169 bpm. The Fenix 6 paired with a chest strap showed 140 and 154 bpm. The largest gap was therefore in the maximum, and the charts did not follow the same pattern throughout.
That was enough for me to avoid relying on the optical sensor during important sessions. It does not prove that every Epix always reads incorrectly: wrist measurements depend on fit, temperature, arm movement, skin and exercise type. For intervals or training controlled by heart rate, I would still use a chest strap.
Running power: Garmin and Stryd use different scales
During one run, the Epix reported an average of 291 W and Stryd reported 234 W. These numbers are not directly interchangeable because the companies use different models and there is no single universal standard for running power. Garmin made the same point when responding to my question.
The practical lesson is to use one source consistently when tracking a trend. I would not transfer power zones from Stryd to Garmin, or the other way round, without setting new thresholds.
Navigation and incident detection
Following a preloaded course
Following a route prepared in advance worked well during races and hikes. Maps look clear on the AMOLED screen and the basic prompts are easy to read while moving. I was less impressed by on-watch rerouting. On a family hike to Wielka Racza, the Epix told me to turn back for more than 3 km instead of offering a useful alternative route.
Incident detection did not trigger after my fall
I fell and twisted my ankle during one trail run, but the watch did not trigger an alert. Garmin describes incident detection as a supplemental feature available only for selected outdoor activities. It requires emergency contacts, a connected phone, a data plan and network coverage, and should not be treated as the primary way to obtain help.
AMOLED display, battery life and everyday features
AMOLED display
The display was the main reason I chose the Epix over a Fenix 7. Two years later, I still consider it the watch’s greatest strength. It is vibrant, easy to read and excellent for maps and training data.
Battery life
With my settings and use, I usually charged the watch every two or three days. Enabling the pulse oximeter could make charging a daily requirement. That is far below the headline specifications, but Garmin notes that Always-On Display, wrist gesture, GPS, wrist heart rate, notifications and connected sensors all affect endurance.
Garmin rates smartwatch mode at up to 10 days for the 42 mm model, 16 days for 47 mm and 31 days for 51 mm with wrist gesture. With Always-On Display, the figures are up to 4, 6 and 11 days respectively. Any comparison therefore needs the case size and settings.
Flashlight, night mode, music and payments
The built-in LED flashlight became one of my favourite features. Red light is useful at home without waking anyone, while the white light provides an emergency option outdoors. I also like the red night mode, Garmin Pay, music support and headphone pairing.
I treat race predictions cautiously. Before a half marathon, the watch predicted 1:55 and I ran 1:36. It can provide context, but it should not replace an honest assessment of current training.
Garmin Epix Pro Gen 2 pros and cons
Pros
- excellent AMOLED display,
- very strong outdoor distance results in my track and trail tests,
- clear maps and good guidance on a preloaded course,
- useful LED flashlight with red light,
- Garmin Pay, music and a broad sports feature set.
Cons
- a large treadmill-distance error in my test,
- heart-rate discrepancies versus a chest strap,
- running power that cannot be compared directly with Stryd,
- poor alternative-route behaviour in the situation described,
- short real-world battery life with my settings,
- a high price.
Who is it for?
The Epix Pro Gen 2 makes sense if you value an AMOLED display, maps, extensive sport profiles and outdoor features more than maximum battery life. It suits recreational running, trail training and mountain hiking, especially when you prepare a course in advance.
If your priority is precise heart-rate intervals, consistent power-based training or multi-day battery life, budget for a chest strap, stick to one power source and compare alternatives. You can also read my Garmin Forerunner 170 Music review and long-term Polar Grit X2 Pro Titan review.
Verdict: was the Garmin Epix Pro Gen 2 a flop?
I would not call it a complete flop. The display, maps, flashlight and outdoor distance tracking can all be excellent. At the same time, too many important areas in my use required verification or compromise for me to call it unquestionably worth the premium price.
After two years I still like and use it, but I do not trust it blindly. It is sufficient for my recreational running and mountain walks. For structured training, I continue to use external sensors and check the settings instead of assuming an expensive watch must always have the right answer.
Garmin Epix Pro Gen 2 FAQ
Does the Garmin Epix Pro Gen 2 measure distance accurately?
It was excellent on the athletics track and trail in my comparisons. On the treadmill it overestimated 5 km as 5.5 km, so that mode needed calibration or correction.
Is wrist heart rate reliable?
The Epix differed from a chest strap in the run shown here, especially at maximum heart rate. I would use a chest strap for important intervals and zone-based training.
Can Garmin running power be compared with Stryd?
Not directly. They use different calculation models. Choose one source and establish training zones specifically for it.
How long does the battery last?
I usually saw two to three days, but case size, Always-On Display, GPS, pulse oximeter and other settings make a major difference. Garmin’s ratings are higher under defined conditions.
Is it good for hiking and trail use?
Yes, particularly with a preloaded course. The maps and display are strong, although automatic rerouting disappointed me in the hike described above.
Does incident detection replace a phone or emergency beacon?
No. Garmin calls it a supplemental feature, and it depends on factors including a supported activity, a paired phone, mobile data and network coverage.
Is the Garmin Epix Pro Gen 2 worth buying?
It can be, if you prioritise AMOLED, maps, the flashlight and a broad feature set, and find it at a good price. I would not buy it expecting every training metric to be perfect without external sensors.
