Two watches, two philosophies. The Garmin Forerunner 570 carries 23 years of running science and the deepest analytics ecosystem in the industry. The COROS PACE 4 showed up lighter, cheaper, and unconcerned with convention -- a 26g rocket that matches or beats Garmin's hardware while undercutting on price.
This is an honest, data-driven comparison to tell you which watch is better for your running.
Quick Verdict
COROS PACE 4
The better pure running watch per dollar. Garmin wins on analytics depth and lifestyle features.

硬件：钛金属vs.聚合物
The Forerunner 570 features a vibrant 1.4" AMOLED display, stainless steel bezel, and Garmin's Elevate v5 HR sensor (green + red + IR LEDs). At 38g, it's light for its feature set. Five physical buttons plus touchscreen give you the best of both input methods.
The PACE 4 weighs just 26g -- less than a AAA battery. A fiber-reinforced polymer body and always-on MIP display trade visual punch for zero screen battery drain. Digital dial + one button keep things minimal.
| Spec | Garmin FR 570 | COROS PACE 4 |
|---|---|---|
| Weight | 38g | 26g |
| Display | 1.4" AMOLED, touch + buttons | 1.3" MIP, always-on |
| GPS battery | 30 hours (multi-band) | 38 hours (multi-band) |
| Music | Spotify, Amazon, Deezer offline | No |
| NFC payments | Garmin Pay | No |
| Running power | Requires accessory ($130+) | Built-in (free) |
| Skin temperature | Yes | No |
| Price | $299 | $229 |
Why Weight Matters
Over a 3-hour marathon or 30-hour ultra, 12g of difference creates cumulative weight awareness. Ultrarunners consistently rate watch weight as a top-three purchase criterion.
GPS精度
Both support multi-band GNSS and deliver sub-1% distance error in most conditions. 在测试中， COROS showed a slight edge in urban canyons; Garmin was marginally more consistent on open courses. The differences are within test-to-test variability.
COROS locks satellites 3-5 seconds faster from cold start -- a minor but real convenience.
GPS Accuracy
Tie Winner
Both deliver sub-1% distance error with multi-band GNSS. No meaningful real-world advantage for either.

心率精度
Garmin's Elevate v5 (three wavelengths) holds a consistent edge, especially during intervals where it captures rapid HR transitions 2-3 seconds faster than COROS's dual-wavelength sensor.
Get a Chest Strap Either Way
A $229 COROS + $70 Polar H10 produces more accurate HR data than a $299 Garmin on wrist sensor alone. If you train by zones, invest in a 胸带 regardless of which watch you choose.
Wrist HR Accuracy
Garmin Forerunner 570 Winner
Elevate v5 produces consistently lower error rates across all activity types, with the biggest advantage during interval training.

训练功能
This is where the real differences live.
Garmin gives you Training Status (6 categories), Training Readiness (daily 0-100 score), PacePro (elevation-aware race pacing), Running Dynamics (with accessories), and the massive Connect IQ ecosystem. It's the deepest training analytics platform in running.
COROS offers EvoLab with 训练负荷, VO2 Max, race predictor, and threshold pace -- presented more cleanly with fewer layers. Built-in running power at no extra cost is a major differentiator. COROS Coach provides free AI-generated adaptive plans.

| Feature | Feature | Garmin FR 570 | COROS PACE 4 |
|---|---|---|---|
| Training Status | Training Status | 6 categories | Load graph with optimal zone |
| Daily Readiness | Daily Readiness | Yes (0-100) | Recovery timer only |
| Race Predictor | Race Predictor | Conservative estimates | Slightly optimistic |
| PacePro (race pacing) | PacePro (race pacing) | Yes, elevation-aware | No |
| Running Power | Running Power | Requires $130+ accessory | Built-in, free |
| Music / NFC | Music / NFC | Yes / Yes | No / No |
| Maps | Maps | Breadcrumb + basic | Breadcrumb only |
Running Power: The $130 Difference
COROS includes wrist-based running power for free. Garmin requires HRM-Pro Plus ($130) or Stryd ($230). If power-based training matters to you, COROS delivers this out of the box.
续航表现
COROS wins at every level, and the margin is decisive.
| Mode | Garmin FR 570 | COROS PACE 4 |
|---|---|---|
| Smartwatch | 14 days | 21 days |
| GPS (multi-band) | 30 hours | 38 hours |
| GPS (standard) | 42 hours | 55 hours |
| GPS + music | 8 hours | N/A |
| UltraMax mode | 60 hours | 70 hours |
The MIP display draws essentially zero power vs. AMOLED's constant drain. Eight extra GPS hours is the difference between a watch that dies at mile 85 of a 100-miler and one that records the finish.
Battery Life
COROS PACE 4 Winner
38 hours of multi-band GPS from a 26g watch. For ultrarunners, this is decisive.

Value for Money
COROS PACE 4 Winner
$229 gets multi-band GPS, built-in running power, 38h battery, and 26g weight. The Garmin is the better watch; the COROS is the better running watch per dollar.

Frequently Asked Questions
If you use it as a daily smartwatch too, yes. The display transforms it into a lifestyle device. If you only care about running and battery, the COROS MIP serves equally well with 8 extra GPS hours.
COROS wrist-based power shows ~5-8% higher variance than Stryd in controlled testing. For comparing your own workouts relatively, it's functional and free. For absolute power measurement, Stryd remains the gold standard at $230.
Absolutely. Accurate GPS, HR monitoring, structured workouts, and battery that outlasts any marathon. You won't have PacePro elevation pacing, but manual pace alerts achieve a similar result.
Garmin retains 55-65% after one year vs. COROS at 45-55%. The absolute difference is modest ($30-50). Neither is an investment.
No. FR 570 launched early 2026, PACE 4 late 2025. Neither successor is expected before 2027. Regular firmware updates improve both watches over time.
