Coros put two very similar running watches on the shelf a year apart, and the cheaper one is the newer one. The Pace Pro launched in October 2024 at $349. The Pace 4 arrived in November 2025 at $249. Both use AMOLED screens, multi-band GPS, and 5 ATM water resistance, so the decision comes down to screen size, storage, sensors, and weight.

Deep Dive Comparison
Design & Comfort
Both watches use a fiber-reinforced polymer case, which is how Coros keeps the weight down. The Pace Pro adds mineral glass over the display. The Pace 4 is the smaller of the two at 43.4mm and 32 grams, against 46mm and 37 grams for the Pace Pro.
Five grams sounds like nothing until you sleep in the watch or run a long race. On a smaller wrist, the 46mm Pace Pro case overhangs. If you have ever taken a watch off during a run because it bounced, the Pace 4 is the safer pick. If your wrist handles a 46mm case fine, the extra size buys you a bigger screen.
Battery Life
Daily-wear numbers are close enough to call a tie. The Pace Pro rates 480 hours, or 20 days. The Pace 4 rates 456 hours, or 19 days. One day apart over three weeks does not change how often you charge.
The GPS number flips the other way. The Pace 4 holds 41 hours with multi-band GPS running. The Pace Pro holds 38 hours. Both cover a 100-mile ultra with room left over, and both survive a full marathon block on one charge. The Pace 4 just gets there with a slightly newer chip and a smaller screen to feed.
Health & Fitness Features
Both watches read optical heart rate at the wrist, track blood oxygen, and use multi-band GPS. Multi-band is the meaningful part here: it locks onto two satellite frequencies at once, which cleans up your track in city blocks and under tree cover. Neither watch makes you pay extra for it.
The Pace Pro adds an ECG sensor. The Pace 4 does not have one. If heart-rhythm readings are on your list, that is a clear point for the Pace Pro.
The Pace 4 answers with a broader motion and environment set: barometric altimeter, accelerometer, gyroscope, 3D compass, and a thermometer. The Pace Pro lists a barometric altimeter and accelerometer. For trail runners and hikers who want a compass bearing and ambient temperature on the wrist, the Pace 4 covers more ground.
Smart Features
Storage is the real split. The Pace Pro has 32GB, which holds a few thousand songs. The Pace 4 has 4GB, enough for a few playlists and not much else. Both have a mic and speaker.
Neither watch does NFC payments. If you want to tap your wrist at a coffee shop after a run, neither of these is your watch. The Pace Pro also carries ANT+ alongside Bluetooth and Wi-Fi, which is how it talks to older chest straps, cycling power meters, and gym equipment. The Pace 4 drops ANT+. Most current sensors pair over Bluetooth, but check your gear before you buy.
Price & Value
The Pace 4 launched at $249 and the Pace Pro at $349. Since the Pace Pro is the older model, it discounts more often, and a sale can narrow the gap to $50 or less. Watch for that before you decide.
At full price, the Pace 4 is the better buy for most runners. You get newer hardware, more GPS battery, a lighter case, and a wider sensor set for $100 less. The $100 upgrade to the Pace Pro buys a bigger and sharper screen, 32GB of music storage, ECG, and ANT+. Those are four real differences, not one. Whether they add up to $100 depends on how many of them you will actually use.

The Verdict
Buy the Coros Pace 4. It is the newer watch, it costs $100 less, it weighs 5 grams less, and it runs three hours longer on multi-band GPS. For the runner who wants accurate pace, distance, and elevation without paying for extras, it is the better value at $249.
Buy the Coros Pace Pro if you load music onto your watch and leave your phone at home. 32GB against 4GB is not a close call. Also buy it if you want ECG readings, if you own ANT+ chest straps or a power meter, or if a 1.2-inch screen is too small for you to read mid-interval. The 1.3-inch 416 x 416 panel is genuinely easier to glance at while moving.
If the Pace Pro drops to $279 or lower on sale, the math shifts and the bigger screen plus 32GB become hard to argue against. At the full $349, the Pace 4 wins.
Frequently Asked Questions
Is the Coros Pace 4 better than the Pace Pro?
For most runners, yes. The Pace 4 is newer, lighter, cheaper by $100, and lasts three hours longer in multi-band GPS mode. The Pace Pro is better only if you specifically want the bigger screen, 32GB of music storage, ECG, or ANT+ sensor support.
Why does the older Pace Pro cost more than the newer Pace 4?
The Pace Pro sits above the Pace 4 in the Coros lineup, not before it. That $349 price pays for the larger 1.3-inch 416 x 416 display, 32GB of storage instead of 4GB, an ECG sensor, and ANT+ connectivity, none of which the Pace 4 has.
Can I store music on the Coros Pace 4?
Yes, but only a small amount. Its 4GB of storage holds a few playlists, while the Pace Pro’s 32GB fits a full library. If phone-free running with music is part of your routine, the Pace Pro is the right choice.
Do either of these watches support contactless payments?
No. Neither the Pace 4 nor the Pace Pro includes NFC payments. If tapping to pay from your wrist is a must-have, you need to look outside the Coros Pace line.
Which one is better for trail running?
The Pace 4, in most cases. It carries a barometric altimeter, a 3D compass, and a thermometer, and it holds 41 hours of multi-band GPS for long days out. The Pace Pro’s larger screen is easier to read on technical terrain, so pick it if screen size beats sensors for you.
