COROS Pace 4 Review: The Ultralight Triathlon Watch for 2026
What to Look For
The COROS Pace 4 launched in November 2025 as the brand’s most capable entry-level multisport watch, weighing just 32g with the nylon band. Named Best Overall Running Watch by Wirecutter in 2026, it brings a major upgrade in display quality, battery life, and training features over its predecessor. For triathletes seeking an AMOLED watch under £250, the Pace 4 is the standout option in 2026.
Key Features to Consider
- AMOLED display at 1,500 nits — The Pace 4 introduces a vivid 1.2-inch AMOLED screen with 164% higher resolution than the Pace 3. Outdoor readability is excellent even in direct sunlight — a common weakness among budget AMOLED watches
- 41-hour GPS battery — At 41 hours GPS and 19 days daily use, the Pace 4 outperforms most rivals at this price. Full IRONMAN athletes can complete a race with significant battery remaining
- Triathlon and multisport mode — Supports auto-transition detection in triathlon mode, with customisable data screens per discipline and automatic swim, bike, and run recognition
- 32g ultra-light build — One of the lightest GPS watches with AMOLED available. Athletes who dislike wrist bulk will notice the difference immediately over heavier options
Our Top Picks
Best Overall: COROS Pace 4 — £229
At £229 the COROS Pace 4 is outstanding value for a multisport watch with AMOLED display, 41-hour GPS battery, and reliable triathlon tracking. Running metrics are exceptional — race predictions, VO2max estimation, marathon training plans, and Virtual Pacer are all included. Multisport mode supports swim, bike, run, and open water with clean data capture. If you want a capable triathlon watch under £250 in 2026, start here.
Best Budget: COROS Pace 3 — ~£180
If the Pace 4 is slightly above budget, the Pace 3 remains excellent at around £180. You lose the AMOLED display (MIP screen instead) and some battery life, but the core COROS ecosystem and training tools are all present. At 30g it is even lighter, and it handles triathlon mode capably. A fine choice for beginners or athletes who don’t need the premium display.
Best Premium: Garmin Forerunner 965 — ~£499
If budget is less of a consideration, the Garmin Forerunner 965 brings the full depth of the Garmin ecosystem: Training Readiness, Body Battery, morning report, Garmin Coach, and the most accurate GPS in a running watch. It is heavier at 53g, but the analytics are unmatched at this price. Worth the investment if you work with a coach on TrainingPeaks or rely on Garmin Connect data extensively.
Buying Tips
- The COROS Pace 4 comes with a nylon band (32g) or silicone band (37g) — for racing, the nylon band is recommended for comfort and weight
- COROS watches pair with Strava, TrainingPeaks, and Apple Health but not Garmin Connect — check your coach’s preferred platform before purchasing
- All three watches above receive regular free firmware updates that add new features over their lifespan
Care and Maintenance
Rinse your watch under fresh water after open water swims and hard sessions to remove salt, chlorine, and sweat. Dry the charging port fully before connecting the cable. The COROS Pace 4 is rated to 5ATM water resistance — safe for swimming but not diving or pressurised water jets.
