Lightweight GPS Watch Built for Ruck Training
The COROS PACE 3 proves you don't need a $600 watch to track demanding ruck workouts. At 30 grams with touchscreen navigation and dual-frequency GPS, it's the lightest serious training watch we've tested under $200.
For $199, the PACE 3 delivers exceptional GPS accuracy, route planning, and battery life in a package light enough to forget you're wearing it during 12-hour events.
Best for: Budget-conscious ruckers who prioritize GPS accuracy and battery life

Durability
The PACE 3 uses a nylon strap with EVA backing that resists sweat degradation better than silicone alternatives. The 11.7mm case profile keeps the watch low enough to avoid snags on plate carriers or ruck straps.
The transflective touchscreen holds up to field use, though COROS wisely includes button navigation as backup when gloves or mud make touch input impractical. We've put this through four-hour rucks in rain without issues. The sapphire crystal option would improve scratch resistance, but the standard mineral glass has proven adequate for trail and urban training.
Comfort
At 30 grams, the PACE 3 disappears on your wrist during long efforts. The nylon band breathes well under weighted packs, and the lightweight design prevents the watch from sliding during movement.
The slim 11.7mm profile means it slides under shirt cuffs and doesn't catch on pack straps. We've worn this for 24-hour training days without wrist fatigue. The band adjustment is simple and stays secure.
The touchscreen responsiveness works well even with sweaty fingers, though we prefer button navigation during active rucking when you can't afford to look down.
Features
Dual-frequency GPS keeps tracks accurate in urban canyons where single-frequency watches drift. The 38-hour GPS battery life covers multi-day events without charging anxiety. Route planning syncs from the app and displays clearly with breadcrumb navigation.
Heart rate monitoring provides reliable data for zone training, though it struggles during heavy ruck movement like most optical sensors. The barometric altimeter tracks elevation gain accurately for hill training. Sleep tracking offers recovery insights between hard sessions.
Activity modes cover running, trail running, and hiking. There's no dedicated ruck mode, but trail run mode captures the data you need. Training plan integration helps structure progressive overload.
Value
At $199, the PACE 3 competes directly with watches costing twice as much. You get dual-frequency GPS, touchscreen navigation, and 38-hour battery life for less than a Garmin Forerunner 255.
The feature set prioritizes what matters for ruck training: accurate tracking, long battery life, and route navigation. COROS skips the smartwatch features that drain batteries and add cost. You're paying for performance, not notifications.
The 24-day daily use battery means you charge monthly, not weekly. For athletes who train daily and need reliable GPS, this represents exceptional value in the sub-$200 category.

Frequently Asked Questions
Does the PACE 3 track rucking workouts?
There's no dedicated ruck mode, but trail run mode captures GPS tracks, elevation, heart rate, and distance accurately. You can rename activities in the COROS app after workouts.
How accurate is the GPS in cities?
The dual-frequency GPS chipset maintains accuracy even in downtown areas with tall buildings where single-frequency watches lose signal. We've tested it in urban canyons with consistent results.
Will the battery last through a GORUCK Heavy?
Yes. The 38-hour continuous GPS mode covers even the longest endurance events. A typical 12-hour Heavy uses about one-third of the battery capacity.
Can I navigate routes during rucks?
Yes. Build routes in the COROS app and sync them to the watch. Breadcrumb navigation shows your path and keeps other metrics visible on screen simultaneously.
How does this compare to Garmin watches?
The PACE 3 matches Garmin's mid-tier GPS accuracy and battery life at half the price. You sacrifice some smart features but gain better battery efficiency and lighter weight.
