The COROS Pace 3 is a sub-$250 GPS running watch that, based on official specifications and the consensus of published reviews, delivers features usually reserved for pricier models: dual-frequency (L1+L5) satellite positioning, an ultralight ~30 gram body, multi-week battery life, and 4GB of onboard music storage. It is not a full smartwatch and it does not try to be—there is no ECG, no cellular option, and its “smart” features are minimal. Instead, it concentrates on accurate, long-lasting run and workout tracking, which is exactly why it earns strong marks from runners looking for value.
[[AFFDISCLOSURE]]
- At roughly 30 grams it is one of the lightest GPS watches you can buy
- Dual-frequency GNSS improves tracking accuracy in cities and under tree cover
- Battery lasts up to ~24 days in daily use and ~38 hours in standard GPS
- It prioritizes running and training over smartwatch extras like ECG or LTE
What is the COROS Pace 3?
Released in August 2023, the Pace 3 is the third generation of COROS’s entry-level running watch. COROS is a brand focused specifically on endurance sports—running, triathlon, and trail—rather than general lifestyle wearables. The Pace 3 reflects that focus. It pairs a 1.2-inch always-on memory-in-pixel display with both a touchscreen and a physical digital dial, so you can operate it with sweaty or gloved hands mid-run.
Two band options change the weight: about 30 grams with the woven nylon band or roughly 39 grams with the silicone band. Either way it sits among the lightest GPS watches on the market, which reviewers consistently note is one of its standout traits on long efforts.
Positioning and accuracy
The headline feature at this price is dual-frequency GNSS. Most budget watches receive a single satellite frequency (L1); the Pace 3 can also receive the L5 band, which helps the watch reject signal reflections that bounce off buildings and dense tree canopy. In practical terms, published reviews report tighter, more faithful GPS tracks in urban “canyons” and on wooded trails compared with single-frequency watches, at the cost of shorter battery life when the dual-frequency mode is active.
You can choose the trade-off yourself: standard GPS stretches battery life dramatically, while the all-systems dual-frequency mode maximizes accuracy for races and technical routes.
Battery life
Battery endurance is another area where the Pace 3 punches above its price. COROS rates it at up to 24 days of regular daily use, up to 38 hours in standard full GPS, and roughly 15 hours in the most demanding dual-frequency setting. That is enough to track a full marathon, an ultra, or a week of training on a single charge—territory usually occupied by watches costing far more. If you want to see how it stacks up against other wearables, our guide comparing smartwatch battery life puts these numbers in context, and our battery-saving tips apply here too.
Training and health features
For a budget watch, the training toolkit is deep. The Pace 3 supports:
- Wrist-based running power (no separate accessory needed)
- Track-run mode that snaps your path to standard lane distances
- Recovery, training load, and effort-pace metrics via the COROS app
- Optical heart rate, plus blood-oxygen (SpO2) spot checks and sleep tracking
- Breadcrumb navigation and offline map support for following routes
- 4GB of storage for offline music
As with all wrist wearables, treat the health readings as wellness estimates rather than medical measurements. Optical heart rate can lag during hard intervals, and SpO2 is a snapshot, not a diagnostic—our explainers on how accurate SpO2 is and how reliable calorie counts are explain why.

What it leaves out
The Pace 3’s low price and long battery come from a focused feature set. It has no ECG sensor, no cellular/LTE option, no built-in speaker or microphone for calls, and a limited app ecosystem compared with Apple or Samsung. Smart notifications are display-only. Its 5 ATM (50m) water resistance handles swimming and rain but is not a dive rating—see our overview of water-resistance ratings for what that means in practice.
How it compares
- Pace 3: ~$229 price point
- Pace 3: ~30g, dual-frequency GPS, up to 24-day battery
- Pace 3: Running-first, no ECG or LTE
- Often $400-$900
- Adds maps, ECG, LTE, larger app store
Against pricier multisport watches, the Pace 3 concedes full color mapping, ECG, and cellular connectivity. What it keeps—accurate dual-frequency tracking, excellent battery, feathery weight, and a serious training platform—covers what most dedicated runners actually use week to week.
Who should buy it
The Pace 3 is an easy recommendation for new and intermediate runners, budget-conscious triathletes, and anyone who wants trustworthy GPS and long battery life without paying flagship prices. If you need a do-everything smartwatch with contactless payments, an app store, and phone calls from the wrist, look elsewhere. If you want a lightweight, focused running tool that outperforms its price tag, this is one of the strongest values available.
Frequently asked questions
Is the COROS Pace 3 accurate for GPS?
Published reviews generally rate its GPS as very good for the price. Its dual-frequency (L1+L5) mode improves accuracy in cities and under tree cover, where single-frequency watches tend to drift. No watch is flawless, but for road and most trail running it is considered reliable.
How long does the battery last?
COROS rates it at up to 24 days in daily smartwatch use, up to 38 hours in standard GPS, and about 15 hours in the most accurate dual-frequency mode. Real-world figures vary with settings, GPS mode, and features like always-on display.
Can the COROS Pace 3 track sleep and heart rate?
Yes. It offers continuous optical heart rate, SpO2 spot checks, and automatic sleep tracking through the COROS app. As with any wearable, treat these as wellness estimates; see our guide on how accurately smartwatches track sleep stages.
Does it work with an iPhone and Android?
Yes. The Pace 3 pairs over Bluetooth with the free COROS app on both iOS and Android and uses Wi-Fi for software updates. It does not have a cellular option, so it relies on your phone for notifications and data sync.
