Featherweight GPS Watch Built for Distance
The COROS PACE 3 strips GPS tracking down to essentials: accurate positioning, extended battery, and a weight you'll forget on your wrist. At 30 grams, it's the lightest full-featured GPS watch we've tested for rucking.
The PACE 3 delivers serious GPS accuracy and 38-hour tracking at a weight that won't distract during long rucks. At $199, it undercuts premium watches while matching their core features.
Best for: Ruckers who prioritize battery life and tracking accuracy over smartwatch features

Durability
The 11.7mm profile might look fragile, but the transflective screen resists scratches better than typical touchscreens. We've knocked it against ruck plates and concrete without visible damage.
The nylon band holds up to sweat and repeated adjustments. Water resistance handles rain and stream crossings without issue. This isn't a tank like tactical watches, but it survives real outdoor abuse.
Dual-frequency GPS chipset maintains accuracy in urban canyons and tree cover where cheaper watches drift. Air pressure and elevation sensors add reliability for tracking ruck climbs.
Comfort
At 30 grams with the nylon band, the PACE 3 disappears during wear. Most GPS watches feel noticeable during long rucks—this one doesn't. The slim profile sits flat against your wrist without catching on pack straps or sleeves.
The always-on touchscreen responds reliably with sweaty or wet fingers. No fumbling with tiny buttons mid-ruck. The display stays readable in direct sunlight, crucial for navigation when you're moving.
24/7 wear comfort is real. We've tested sleep tracking, and the watch never causes wrist fatigue or pressure points overnight.
Features
Route planning through the COROS app syncs directly to the watch—build your ruck route at home, follow breadcrumb navigation without pulling out your phone. Turn-by-turn directions stay visible alongside heart rate and distance data.
Heart rate monitoring tracks effort zones accurately compared to chest straps. The extensive activity modes include trail running and hiking profiles that translate perfectly to rucking metrics. Elevation gain tracking proves surprisingly accurate on hill rucks.
38 hours of continuous GPS crushes competitors in this price range. For daily wear, 24 days between charges means you charge it twice a month, not twice a week. That reliability matters when training consistently.
Value
At $199, the PACE 3 costs half what Garmin charges for similar battery life and GPS accuracy. You sacrifice some smartwatch features—no music storage, limited app ecosystem—but gain focus on core tracking functions.
The feature set matches watches priced $100-200 higher. Dual-frequency GPS, extended battery, and accurate sensors typically live in $300+ devices. COROS built this for athletes who track movement, not notifications.
For ruckers, this watch delivers exactly what matters: reliable tracking, comfortable wear, and battery life that lasts through multi-day events. The price makes it accessible without feeling like a compromise.

Frequently Asked Questions
How long does the battery last during a typical ruck?
With continuous GPS tracking, you get 38 hours—enough for multiple marathon-distance rucks or multi-day events. Normal daily wear with occasional GPS use lasts 24 days between charges.
Will this track elevation gain accurately on hill rucks?
Yes. The PACE 3 uses both GPS and air pressure sensors to track elevation gain. We've found it matches known climb totals within 50-100 feet on typical ruck routes.
Can I load custom ruck routes onto the watch?
Absolutely. Build routes in the COROS app or search destinations, then sync to the watch. Breadcrumb navigation shows your path while keeping distance and heart rate visible on screen.
Is 30 grams actually noticeable compared to heavier watches?
The difference matters during 2-3 hour rucks. Heavier watches create fatigue points on your wrist. The PACE 3 weight disappears—you stop thinking about it after the first mile.
Does the touchscreen work with gloves?
Not with thick gloves. The touchscreen responds to bare skin or thin liner gloves. For winter rucking, you'll need to use it bare-handed or with touchscreen-compatible gloves.
