Do I really need a Fenix or Epix to train seriously? After testing the Garmin Forerunner 570, I have fewer reasons to pay for a flagship. Wrist heart rate worked well during steadier efforts, GPS gave me little to complain about, and the watch recorded 5,090 m over 12 laps in lane four on the track. One compromise could still change the buying decision: there are no topographic maps.
I tested the 47 mm model while running, on an athletics track and treadmill, cycling, swimming, lifting weights and heading outdoors. This is my practical review, rather than a promise that one watch suits everyone. I see its strongest appeal for someone who trains consistently and wants to avoid paying for features they rarely use.

Two sizes and a light build: 42 or 47 mm?
The Forerunner 570 comes in two sizes, with a 1.2-inch AMOLED display on the smaller version and a 1.4-inch panel on the larger one. I used the larger model and liked the fit. Having a smaller option matters, though: a big case is not automatically the most comfortable choice for a slimmer wrist.
This is a light sports watch with an aluminium bezel and Gorilla Glass 3. There is no sapphire lens or titanium bezel. Comfort during training is a strong selling point for me, but I would also consider how I tend to treat my watches. I did not conduct an impact or scratch-resistance test.
AMOLED and buttons: readable when it matters
The display was an immediate highlight. I could read pace in bright sunshine, the interface felt smooth and touch input responded well. A nice-looking watch face is one thing; being able to glance at training data without breaking concentration matters more to me.
Physical buttons are still here, thankfully. They are my preferred controls with wet hands or gloves. Workout animations are a welcome extra, but reliable operation matters more to me during exercise. The compass photo below illustrates the screen; it is not a measurement of compass accuracy.
Wrist heart rate versus a chest strap: beyond the average
For comparison sessions, I wore an Epix connected to a chest strap and the Forerunner 570 using wrist heart rate. In one run, the strap recorded an average of 138 bpm and a maximum of 164 bpm. The Forerunner recorded 137 and 171 bpm respectively. That is a one-beat gap in the averages and a seven-beat gap in the maxima.
Across most steady sessions described in my test, average heart-rate differences stayed within three beats. Sharp changes in intensity were less convincing: the wrist reading sometimes produced a higher peak, with gaps around 10 bpm. I was happy using it for everyday running, but I would still choose a chest strap for short intervals.
Similar averages do not prove that two heart-rate traces match. Without synchronised recordings, I cannot calculate sample-by-sample error or response delay. My experiences with the same sensor generation in other Garmin watches have also varied, and I do not have the evidence to explain why.
| Metric | Epix + chest strap | Forerunner 570 |
|---|---|---|
| Average HR | 138 bpm | 137 bpm |
| Maximum HR | 164 bpm | 171 bpm |
GPS: good results in the woods, hills and on the bike
The Forerunner 570 supports multi-band GNSS. I compared recordings with devices including an Epix Pro Gen 2 and a Garmin bike computer. In woodland, on mountain outings and while cycling, I found the differences small. I did not feel that choosing this model meant giving up dependable location tracking.
That is an assessment from use and recording comparisons, rather than a measured laboratory error in metres. The track-overlay image provides context, but it cannot establish an accuracy percentage without the activity files. Another watch or bike computer is not a surveyed reference route either.
No maps: the main compromise
I can follow a course line, but there is no topographic map showing the surrounding terrain and paths. On familiar roads or park routes, I rarely miss that context. At an unfamiliar forest junction, a line on its own can be much less helpful than a full map.
I also found the return-navigation workflow frustrating on my outings. Straight-line guidance does not account for terrain obstacles, while retracing the recorded route did not always match how I wanted to turn back. That is my experience of the navigation workflow in those situations, rather than a claim that the feature never works.
If exploring unfamiliar trails were my priority, maps would be my main reason to move up the range. My Forerunner 970 review covers that broader feature set. I would not assume that every runner needs wrist-based maps, though.
Track test: 12 laps in lane four, 5,090 m recorded
On the athletics track, I selected Track Run, set lane four and ran 12 complete laps. The watch recorded 5,090 m. In my test notes, I used an expected range of roughly 5,050–5,145 m to account for the line I ran. The result landed within that range, which I consider a strong outcome.
It does not establish zero error. I do not have a surveyed measurement of the exact line I ran, and Track Run uses its own processing. I see it as a successful practical test, rather than a result that applies to every track and every session.
Treadmill: 4,250 m and a need for calibration
Indoors, I was less impressed. Without an external sensor, the watch recorded 4,250 m, which I judged too short relative to the treadmill. I did not state the treadmill’s exact displayed distance in the transcript, so I cannot give a percentage error or a precise number of missing metres.
Garmin offers Calibrate & Save after a sufficiently long treadmill session, allowing the treadmill distance to be entered. That helps tidy up the activity record, although a treadmill display is not automatically a laboratory reference. Correcting distance does not prove that every other training metric becomes accurate.
Training tools: plenty to use, with a few omissions
Training status, load, readiness and workout suggestions make a useful everyday toolkit. What matters to me is whether the information helps organise training and understand my response to it, rather than how many items appear in a menu. None of these features guarantees a personal best.
Compared with higher models, omissions include Real-Time Stamina, Running Tolerance, Running Economy and Step Speed Loss. The last two also require the HRM 600 chest strap on the Forerunner 970. Paying more for the watch alone does not necessarily unlock every metric.
My priorities remain useful run recordings, usable heart rate and comfort. More advanced metrics can be worthwhile when I know how I plan to use them. I would not pay for them simply because they sit higher in a specification table.

Cycling, swimming and strength: more than a running watch
On the bike, compatible accessories include power meters, Varia radar and trainers. I personally prefer a bike computer because its screen is easier for me to read on the bars, but the Forerunner’s role extends well beyond running. It also worked well as a cycling training tool in my use.
In the pool, stroke recognition and distance counting generally worked well, although occasional lengths were missed or added. Drill Log is especially useful: when doing kickboard work without normal arm strokes, I can enter the drill distance. That is a practical feature I value more than an impressive extra I never open.
During strength sessions, I could edit reps and weight, while animated workouts helped guide exercises. Automatic exercise recognition is imperfect, especially when the wrist barely moves. After hard lifting, Body Battery did not always reflect how tired I felt; I see that as a limitation of the indicator, rather than a diagnosis of recovery.

Battery life: around four days in my use
I used the 47 mm model with the always-on display enabled and multi-band GPS for outdoor activities. The period included strength training, three hours of cycling, track and treadmill sessions, swimming and about an hour of forest running. I got around four days of continuous everyday wear, which I found reasonable for that workload.
I would not compare those four days directly with the manufacturer’s maximum figures, because settings and activity time differ. I did not separately test the smaller model or run a battery trial with AOD disabled. For multi-day outings with fewer charging stops, I would also consider the experience in my Garmin Enduro 3 review.
Music, calls and the flashlight: useful details
There is 8 GB of storage, including space for music. Supported music services may require a suitable subscription. A microphone and speaker enable calls through a compatible paired phone; this is not standalone cellular connectivity. I did not conduct a separate call-quality test.
There is no ECG feature or dedicated LED flashlight. The flashlight function lights up the display. It is useful for finding keys or moving around a dark room, but it would not replace a headtorch for a night run. The photo shows the screen illuminated red, rather than a separate LED in the case.
Race preparation: the watch is part of the plan
For race preparation, I would start with my actual training week: where I run, whether I do short intervals, how much I swim and whether I need maps. My test points to a clear split: track sessions and everyday running suit the 570, treadmill distance needs attention, and unfamiliar trails make maps more attractive.
I would also keep equipment, race logistics and training tasks organised alongside the watch data. No readiness score replaces those practical decisions, and buying a more expensive model does not remove the need to plan.
Verdict: who is the Forerunner 570 for?
For me, this is a strong choice for regular running, track sessions and multisport training when maps are not a priority. I get a comfortable watch, an easy-to-read screen and measurements I was happy with in most of the situations described. Serious training alone does not make a Fenix necessary.
I would spend more for a specific need: maps, different materials, a dedicated flashlight, longer battery life in a particular mode or selected metrics. I would not call the 570 the best watch for everyone or assume a fixed price gap to alternatives. Current pricing can change its value, but it does not change its limitations.
My main buying condition is simple: be sure that course-line navigation is enough. If it is, the Forerunner 570 is one of the Garmin watches I find most convincing for everyday training. Would you pay extra for maps, or choose a lighter feature set?
Frequently asked questions
Does the Garmin Forerunner 570 have maps? There are no topographic maps. You can follow courses using a route line.
Do I still need a chest strap? Wrist heart rate was sufficient for my steadier sessions. For short, intense intervals, I would still choose a strap: similar averages do not mean identical peaks.
How long does the battery last? My 47 mm test unit lasted around four days with AOD and multi-band GPS during outdoor activities. That is my usage result, rather than a guarantee for everyone.
Is it suitable for triathlon? It is a multisport watch with triathlon support. I tested running, cycling and pool swimming, but that is not a separate full-race triathlon test.
Does it have a dedicated LED flashlight? No. Its flashlight mode uses the display, rather than a separate LED in the case.
