The watch on the wrist is not the thing you keep. What you keep is the file it writes, and that is the quietest difference in the whole GPS running watch vs smartwatch argument. One category is built around producing a record somebody else can read; the other is built around a screen you look at.
This is an independent editorial review. Garmin did not review or approve this article.
The file format described below is a community specification rather than a rule. It obliges no watch maker to support it and no buyer to care about it, and it appears here because it is the only open format in which the two categories can be compared on equal terms.
This article is about buying a device and reading what it writes. A watch that estimates effort, pace or heart rate is not a diagnostic instrument, and questions about training load or any symptom felt while running are for a qualified professional to answer, not a product page.
GPS running watch vs smartwatch: the table that sorts the categories
Every row below is something you can check before buying, which is more than can be said for most wearable comparisons.
| Variable | Running watch | General smartwatch |
|---|---|---|
| What the device is designed to produce | A recorded activity file | Notifications, apps and a daily summary |
| Fields captured during a run | Dozens, including running-form measures | Usually distance, pace and heart rate |
| Portability of that record | Exportable to an open interchange format | Depends entirely on the health platform |
| What survives the export | Position and time, plus extensions if the reader supports them | Same limit, with less to lose |
| Display priority | Readable mid-run | Readable at a desk |
| Who the spec sheet is written for | Someone comparing training features | Someone comparing lifestyle features |
The open format stops at position and time
GPX, the GPS Exchange Format, is how activity data moves between programs that were not built by the same company. Its maintainers describe it as “a light-weight XML data format for the interchange of GPS data” covering “(waypoints, routes, and tracks) between applications and Web services on the Internet,” and note that it “has been the de-facto XML standard for lightweight interchange of GPS data since the initial GPX 1.0 release in 2002.” It is, in their words, “an open standard.”
Three things, then: waypoints, routes and tracks. A track is defined structurally, as segments where “A Track Segment holds a list of Track Points which are logically connected in order,” with the instruction to “start a new Track Segment for each continuous span of track data.” Anything a manufacturer wants to carry beyond that travels as a private element, and the format’s own guidance is that if you include private elements “you need to reference that namespace as well.” The receiving program may simply ignore them.
What the running watch records, and what the file can carry
This is where the categories separate. Garmin’s own data fields documentation lists what a running watch is measuring while you are out, and it is a long way past position and time. Ground Contact Time is defined as “The amount of time in each step that you spend on the ground while running, measured in milliseconds.” GCT Balance gives “The left/right balance of ground contact time while running.” Vertical Oscillation is “The amount of bounce while you are running,” and Vertical Ratio is “The ratio of vertical oscillation to stride length.” Grade Adjusted Pace is “The average pace adjusted by the steepness of the terrain.” Aerobic and Anaerobic Training Effect describe “The impact of the current activity” on each fitness level.
The same documentation carries three caveats worth reading before you buy anything: “Not all data fields are available for all activity types,” “Some data fields require compatible accessories to display data,” and “Some data fields appear in more than one category on the watch.”
The difference between GPS running watch and smartwatch, in one sentence
Stated plainly, the difference between GPS running watch and smartwatch is how much of what the device knows is ever written down in a form another program can read. The running watch knows more, and the open interchange format carries only the oldest and simplest part of it.
- Position and time export cleanly to any program that reads the open format.
- Running-form measures travel as extensions, and a receiving app may ignore them.
- Some fields need an extra accessory before the watch can display them at all.
- A record you cannot export is a record that lives wherever the manufacturer keeps it.
The maker’s own naming admits the categories have merged
It is worth noticing what the manufacturer calls these products. In its own newsroom announcement, Garmin described two recent models as “purpose-built running smartwatches” under the subheading “Easy-to-use GPS running smartwatches are packed with features to help runners of all levels reach their goals.” A current flagship product page is titled as a “Running Smartwatch with GPS.”
Both halves of the comparison are in the product name, which tells you the hardware argument has largely been settled and the remaining differences are in software, display and what gets recorded. The same release describes “vibrant 1.2-inch AMOLED displays” on both models and frames the running and training tools as the core, with health and lifestyle features layered on top.
One scope note: the corporate entity is Garmin International, Inc., described in the same release as “a subsidiary of Garmin Ltd. (NYSE: GRMN),” with Garmin Ltd. “incorporated in Switzerland” and principal subsidiaries “located in the United States, Taiwan and the United Kingdom.”
The current lineup sits here:
Choosing a GPS running watch or smartwatch for beginners
For someone starting out, GPS running watch or smartwatch for beginners comes down to one question: does anybody else ever need to read your runs? A coach, a club, a race entry or a second training app all want a file. If the answer is no, a general smartwatch covers the ground and does more the rest of the day.
Five checks that settle the category question
- Decide whether your runs need to leave the manufacturer’s app. That single answer decides most of this.
- Check which fields need an accessory, because a headline feature list does not separate built-in from add-on.
- Look at the display technology, since a screen chosen for a desk and one chosen for bright sunlight are different compromises.
- Check what the product page actually publishes. A page that lists a bright display and built-in maps and no measurements is telling you to read the manual instead.
- Confirm that the fields you care about are supported for the activity you do, not merely present on the watch.

Frequently Asked Questions
Four more follow naturally once the comparison is framed around the record rather than the wrist.
Ques: Can I get my runs out of any watch?
Usually the position and time can leave, because the open interchange format is widely supported. The running-form measures are the part that may not travel, since they sit in extensions a receiving program is free to ignore.
Ques: What decides GPS running watch versus smartwatch for a first-time buyer?
The practical test for GPS running watch versus smartwatch is whether a second piece of software ever needs your data. One file export settles more arguments than any feature table.
Ques: Why do product pages list so few specifications?
On this brand the detail lives in the owner manuals rather than on the shop page. A flagship page may name a bright display, built-in maps and a battery claim while the manual defines every recorded field.
Ques: Do I need extra hardware for running-form data?
Sometimes. The manufacturer states directly that some data fields require compatible accessories before the watch can display them, so check that before assuming a listed field is built in.
Bottom line
Compare these two categories on what they write down, not on what they display. The open format carries position and time for everybody; everything that makes a running watch a running watch travels as an extension, and whether that matters depends entirely on who else needs to read your runs.
