🔍 How to Choose the Best Coros Watch for Ultra Running
Choosing the best coros watch for ultra running depends on battery life, GPS accuracy, training features, and durability. Here’s what to consider:
📌 1. Battery Life
Coros is known for its long battery life, but some models last longer than others. If you’re an ultra-runner or endurance athlete, the Vertix 2 (127 hours) or Vertix 2S (118 hours) is unbeatable.
📌 2. GPS & Navigation Features
- Dual-frequency GPS (found in Apex 2 Pro, Vertix 2, and Vertix 2S) offers better accuracy in dense cities or mountains.
- Offline maps are available on Pace Pro, Apex 2 Pro, and Vertix series—useful for trail running.
📌 3. Training & Health Tracking
All Coros watches include:
✔️ Heart Rate & HRV Tracking (for fitness & stress monitoring)
✔️ VO2 Max & Recovery Time (for performance optimization)
✔️ SpO2 & Altimeter (important for high-altitude athletes)
📌 4. Smartwatch Features
If you want music storage and smart notifications, Coros watches provide basic functionality but lack streaming services like Spotify, unlike Garmin models.
Best Coros Watches in 2025: Expert Reviews
1. Coros Pace 3 – Best Overall coros watch for ultra running
💰 Price: ~$229 | ⭐ Rating: 4.7/5
✅ Why Buy It?
- ✔️ Superb battery life (38 hours GPS)
- ✔️ Lightweight (30g with nylon strap)
- ✔️ Accurate GPS & heart rate tracking
❌ Drawbacks:
- ❌ No offline maps
- ❌ Plastic design
The Coros Pace 3 is not only the best Coros watch for Ultra Running in the Coros lineup, but it’s also one of the best value-for-money GPS watches on the market.
It offers a compelling package: outstanding battery life, precise dual-frequency GPS, and a comprehensive set of training, health, and recovery tools.
Battery life is a standout feature, with 24 days of smartwatch use and 38 hours of continuous GPS tracking.
Even with Dual Frequency mode enabled, which improves accuracy, it still lasts 15 hours—far outlasting competitors like the Garmin Forerunner 165 and Forerunner 265.
In our real-world tests, a one-hour run in Dual Frequency mode consumed just 4% battery.
The Pace 3’s training analytics are incredibly advanced for its price. It includes the full suite of EvoLab tools, offering:
- Running Performance tracking
- Training Load Analysis
- Recovery time recommendations
- Aerobic and Anaerobic Fitness Insights
- Customizable training plans via the Coros app
The Pace 3 is lightweight and comfortable at just 30g with a nylon strap. While its plastic design isn’t the most premium, it’s incredibly functional and comfortable for all-day wear.
The dual-frequency GPS performed exceptionally well in our tests, maintaining signal accuracy even in urban environments with tall buildings—a problem for many GPS watches.
While the heart rate sensor has been improved, like most optical sensors, it still struggles during high-intensity workouts.
The mapping features lack full offline maps, but it does include breadcrumb navigation and in-app route planning.
Like all Coros watches, the smartwatch features are minimal—Garmin offers better smartwatch functionality.
However, the Pace 3 includes 4GB of offline MP4 music storage, allowing you to upload and play music directly from the watch.
Verdict: The Coros Pace 3 is an outstanding GPS running watch that balances long battery life, great accuracy, and excellent training tools at a hard-to-beat price.

2. Coros Apex 2 – best coros watch for trail running
💰 Price: ~$349 | ⭐ Rating: 4.6/5
✅ Why Buy It?
- ✔️ Compact & rugged for trail adventures
- ✔️ High-quality sapphire glass & titanium bezel
- ✔️ Good battery life (40 hours GPS)
❌ Drawbacks:
- ❌ No dual-frequency GPS
- ❌ No music streaming
The Coros Apex 2 is a fantastic lightweight adventure watch that balances durability, battery life, and premium training tools at a mid-range price.
If you’re an ultra-runner or trail athlete looking for a compact yet feature-packed GPS watch, this is a strong contender.
The Apex 2 includes the same advanced training and navigation tools found in the Apex 2 Pro and Vertix 2 but in a smaller, lighter package.
🔹 ECG Sensor & HRV Readings – Tracks heart rate variability for better recovery insights.
🔹 Full-color maps – Great for navigation on long trails.
🔹 Durable Build – Features a sapphire glass and a titanium bezel for extra toughness.
The lack of dual-frequency GPS is its main omission, but during testing, the Apex 2 still performed nearly as well as the Apex 2 Pro.
In a half-marathon test, it logged 13.11 miles, compared to the Apex 2 Pro’s 13.3 miles and Garmin Enduro 2’s 13.19 miles.
The optical heart rate sensor was accurate during steady-state runs, but it lagged slightly during high-intensity interval workouts.
The Apex 2 offers up to 40 hours of GPS tracking, which drops to 30 hours in All Systems mode. In our tests, a one-hour run consumed just 4% of the battery, making it a great choice for endurance events.
Its compact and lightweight design (42g with nylon strap) makes it one of the most comfortable trail watches available.
The Coros Apex 2 is a well-balanced multi-sport watch that delivers great GPS tracking, solid battery life, and premium materials without the bulk of larger adventure watches.
If you’re a trail runner or ultra-athlete, this is one of the best lightweight GPS watches for trail runners.
3. Coros Apex 2 Pro – Best for Ultra-Distance Runners
💰 Price: ~$449.00 | ⭐ Rating: 4.5/5
✅ Why Buy It?
- ✔️ Dual-frequency GPS for better accuracy
- ✔️ Long battery life (66 hours GPS)
- ✔️ Comprehensive training & recovery insights
❌ Drawbacks:
- ❌ Heart rate sensor isn’t perfect
- ❌ No onboard music storage
The Coros Apex 2 Pro is an excellent adventure-ready multi-sport watch, offering a rugged yet lightweight design, long battery life, and advanced training tools. I
it sits between the Apex 2 and the more premium Vertix 2, providing a balance of performance, durability, and features.
Compared to the standard Apex 2, the Apex 2 Pro upgrades with:
✔️ A larger, higher-resolution 1.3-inch display
✔️ Longer battery life (66 hours GPS vs. 40 hours on Apex 2)
✔️ Dual-frequency GPS for enhanced accuracy
Despite its rugged construction, the Apex 2 Pro remains lightweight (53g with nylon strap), making it comfortable for 24/7 wear.
It features a premium sapphire glass display and a titanium bezel, ensuring scratch resistance and durability.
While the Apex 2 Pro includes dual-frequency GPS, our tests found no significant improvement over the standard Apex 2.
In dense urban areas, the GPS could still wander slightly, making it less accurate than top competitors like the Garmin Fenix series.
Heart rate tracking was inconsistent during high-intensity workouts, occasionally lagging behind chest strap readings—a common issue with optical sensors.
The Apex 2 Pro features full-color offline maps, which are pre-loaded for easy navigation. However, the navigation system isn’t as refined as Garmin’s.
Features like back-to-start and breadcrumb navigation are useful but lack real-time turn-by-turn guidance.
Apex 2 vs. Apex 2 Pro: Is the Upgrade Worth It?
Unless you need:
✔️ A slightly bigger display
✔️ An extra 26 hours of GPS battery life
✔️ Slightly better materials and design
Then the Apex 2 Pro isn’t a must-have upgrade over the standard Apex 2. The Apex 2 offers nearly identical performance for a lower price.
The Apex 2 Pro is a great choice for endurance athletes and trail runners who need long battery life, durable materials, and solid navigation tools.
However, if budget is a concern, the standard Apex 2 remains the Best GPS watch for ultra marathons.
4. Coros Pace Pro– Best Coros Watch for Bright Display & Mapping
💰 Price: ~$349 | ⭐ Rating: 4.5/5
✅ Why Buy It?
- ✔️Stunning AMOLED display
- ✔️ Offline maps for navigation
- ✔️ ECG sensor for heart health tracking
- ✔️ Long battery life
- ✔️ Dual-frequency GPS
❌ Drawbacks:
- ❌ Heart rate sensor can be inconsistent
- ❌ Slightly heavier than the Pace 3
The Coros Pace Pro is the first Coros watch with an AMOLED display, bringing sharper visuals and improved readability—perfect for runners who value a bright, smartwatch-like experience.
But it’s not just about the screen. The Coros Pace Pro is more than just a pretty screen. It also offers:
- Offline mapping for better navigation
- ECG sensor for heart health tracking
- Dual-frequency GPS for improved accuracy
- SpO2 sensor & barometric altimeter for altitude performance
During our tests, we got:
🔋 31 hours GPS battery life (dual-frequency mode)
⏳ 38 hours in All Systems mode
⚡ 1-hour run in max accuracy mode = only 2% battery drain!
Somehow, despite the power-hungry AMOLED display, Coros has managed to extend GPS battery life to 38 hours in All Systems mode.
Even in high-accuracy Dual Frequency mode, it still offers an impressive 31 hours of GPS runtime—outlasting many AMOLED competitors like the Suunto Race and Polar Vantage M3.
In our tests, the dual-frequency GPS accuracy was excellent, keeping pace with premium models like the Garmin Fenix 8.
However, the heart rate sensor was inconsistent, particularly during interval workouts where we noticed spikes up to 20 bpm higher than a chest strap.
Despite the AMOLED upgrade, the Pace Pro retains the lightweight feel of the Pace 3 but with a slightly heavier build (37g with nylon band vs. 30g for Pace 3).
However, the plastic casing and bezel still feel more functional than premium.
The big question is whether the $100 premium over the Pace 3 is justified. If you prioritize:
✔️ A brighter, sharper AMOLED display
✔️ Offline maps for navigation
✔️ More advanced health tracking (ECG, SpO2, barometer)
Then the Pace Pro is a solid upgrade. However, if battery life and affordability are your biggest concerns, the Coros Pace 3 remains the better value pick.
The Pace Pro is perfect for runners who want a bright display, improved mapping, and better tracking tools. However, it comes at a premium price.
5. Coros Vertix 2S – Best for Extreme Endurance
💰 Price: ~$699 | ⭐ Rating: 4.8/5
✅ Why Buy It?
- ✔️ Huge battery life (118 hours GPS)
- ✔️ Rugged build with adventure-proof durability
- ✔️ Improved heart rate tracking
❌ Drawbacks:
- ❌ No built-in music streaming
- ❌ Lacks flashlight feature
The Coros Vertix 2S is built for extreme endurance athletes who need unmatched battery life, premium training features, and ultra-rugged durability.
If you’re conquering mountain trails, ultramarathons, or multi-day expeditions, this is the best Coros watch for the job.
The Vertix 2S maintains the same size and rugged build as its predecessor, with a Garmin Fenix-like design that’s tough enough for any adventure.
Key upgrades over the Vertix 2 include:
✔️ Improved heart rate accuracy
✔️ More reliable GPS performance
✔️ More advanced navigation tools
It also features Coros EvoLab, offering deep insights into:
- Training performance & recovery
- Fatigue and training load tracking
- Race predictor & VO2 max analysis
The Vertix 2S delivers 118 hours of GPS battery life—only 6 hours less than the Vertix 2 in dual-frequency mode. In our tests, a one-hour run burned just 2% of the battery, meaning most users could go for weeks without charging.
While it doesn’t have the bright AMOLED display of newer Garmin Fenix models, its lower-power screen contributes to its extended battery life.
Despite offering offline music storage, the lack of Spotify integration is a big downside for a premium adventure watch.
Similarly, Garmin’s Fenix lineup includes a built-in flashlight missing on the Vertix 2S. This could be a deal-breaker for night-time adventurers.
However, if you don’t need minor improvements in GPS and heart rate accuracy, the Vertix 2 is still an excellent alternative.
If you need a watch that can last for weeks on a single charge, the Coros Vertix 2S is a powerhouse for extreme endurance athletes.
6. Coros Vertix 2 – Longest Battery Life & Ultimate Adventure Watch
💰 Price: ~$599 | ⭐ Rating: 4.9/5
✅ Why Buy It?
- ✔️ Unmatched battery life (127 hours GPS)
- ✔️ Full-color offline maps
- ✔️ Advanced training & navigation tools
❌ Drawbacks:
- ❌ No music streaming
- ❌ Large & bulky for smaller wrists
The Coros Vertix 2 is the ultimate ultra-endurance watch, designed for expedition athletes, ultra-runners, and adventurers who need unmatched battery life and rugged durability.
With 127 hours of GPS tracking, the Vertix 2 outlasts almost every sports watch on the market.
Even in high-accuracy dual-frequency mode, it delivers 49 hours of battery life—beating most Garmin Fenix and Enduro models.
In testing, a one-hour GPS workout burned just 3% of battery, while a full marathon using dual-frequency GPS used only 7%. That means a single charge could last for weeks of training.
The Vertix 2 features dual-frequency GPS, making it one of the most accurate outdoor watches available.
However, the newer Vertix 2S has slightly improved GPS tracking, which could be a reason to consider upgrading.
The Vertix 2 is a tank—large, rugged, and built to handle extreme conditions. It has a 1.4” display, providing plenty of space for multiple data fields.
Compared to the Vertix 2S, the main difference is the weight and heart rate sensor. The Vertix 2 is slightly heavier and uses an older optical heart rate sensor, which tends to lag slightly during high-intensity workouts.
Unlike some Garmin adventure watches, the Vertix 2 lacks music streaming and a built-in flashlight. While it does offer offline music storage, it’s not compatible with Spotify or other streaming services.
Vertix 2 vs. Vertix 2S: Should You Upgrade?
The Vertix 2 and Vertix 2S are nearly identical. The 2S has better GPS accuracy and a slightly improved heart rate sensor, but the Vertix 2 still wins on overall battery life.
If you find a good deal on the Vertix 2, it remains one of the best endurance watches available.
The Coros Vertix 2 is an unbeatable choice for extreme endurance athletes, offering the longest battery life in the industry, premium GPS tracking, and a rugged build for the toughest adventures.
If you don’t need the slight improvements of the 2S, the Vertix 2 remains a fantastic choice.
