More Details on Our Top Picks
Garmin Forerunner 165 Running Smartwatch, 43mm, Black
The Garmin Forerunner 165 stands out for its bright AMOLED display and long battery life, making it a reliable choice for athletes who want a clear interface during both runs and swims. Compared to the Forerunner 955, it offers fewer advanced navigation features but remains straightforward and user-friendly for everyday training. Its built-in GPS and wrist-based heart rate monitor support most training needs, though it lacks detailed water resistance specs, which might matter for swimmers. This model makes the most sense for runners who also enjoy occasional lap swimming but don’t need exhaustive navigation or recovery metrics. The tradeoff is that it depends on a smartphone for some safety features and notifications, which could be limiting for those seeking a fully independent device.
Pros:- Bright AMOLED display with easy-to-read controls
- Long battery life suitable for extended workouts
- Supports personalized training plans and activity tracking
- Smart notifications and contactless payments
Cons:- Requires smartphone for some safety and notification features
- Limited details on water resistance or durability
Best for: Runners who want a lightweight, versatile watch with good display clarity and long battery life for both running and swimming.
Not ideal for: Triathletes or advanced swimmers seeking detailed water metrics or multi-sport navigation features, as this model offers limited water resistance details and lacks advanced swim tracking.
- Size:43 mm
- Display:AMOLED touchscreen
- Battery Life:Up to 11 days in smartwatch mode, 19 hours in GPS mode
- Features:Built-in GPS, wrist-based heart rate, incident detection, Garmin Pay, smart notifications
- Activity Profiles:25+ including running, cycling, HIIT, strength
Our verdict“This watch is ideal for runners who also swim casually and prefer a straightforward, well-rounded device.”
Garmin Forerunner 955 GPS Running Smartwatch, 46mm, Black
The Garmin Forerunner 955 is suited for serious runners and triathletes who require detailed metrics and navigation. Its always-on full-color display, multi-band GPS with built-in maps, and extensive health tracking put it ahead of the Forerunner 165, especially for navigating complex routes or multi-sport events. The long battery life, with up to 15 days in smartwatch mode, supports extended training and races, but its high price might deter casual users. The complex features, such as HRV and training readiness, require a learning curve, making it less accessible for beginners. If you prioritize performance insights and navigation for outdoor swims and runs, this model makes the most sense, though those with simpler needs should consider more affordable options.
Pros:- Long battery life supporting extended training and races
- Advanced multi-band GPS with built-in maps for precise navigation
- Comprehensive health metrics including HRV and training readiness
- Large, always-on full-color display for easy visibility
Cons:- High price point, potentially limiting for budget-conscious users
- Complex feature set may require time to learn and utilize fully
Best for: Experienced runners and triathletes who need advanced training metrics, precise GPS, and detailed navigation during their workouts.
Not ideal for: Casual exercisers or beginners who may find the extensive features overwhelming or unnecessary for basic training and lap swimming.
- Display:Always-on, full-color
- Size:46mm
- Waterproof:Yes
- Battery Life:Up to 15 days in smartwatch mode, 42 hours in GPS mode
- Navigation:Multi-band GPS with built-in maps
Our verdict“This watch is best suited for dedicated athletes who need detailed analytics and navigation for both running and swimming pursuits.”
Garmin Forerunner 745 GPS Running Watch (Renewed)
The Garmin Forerunner 745, even as a renewed device, offers a versatile package for runners, swimmers, and cyclists. Its detailed training metrics, on-device workouts, and music storage make it a strong contender for those who value multimedia features alongside performance tracking, unlike simpler models like the Forerunner 55. While the music streaming subscription adds convenience, it also introduces ongoing costs, and the device’s high price for a renewed item might be a concern. Its water resistance rating supports lap swimming, making it suitable for dual-purpose workouts. However, it leans heavily toward Garmin ecosystem users, and some advanced metrics require additional accessories like HRM-Pro, which could be a drawback for budget-conscious buyers.
Pros:- Accurate multi-satellite tracking for diverse workouts
- On-device workout suggestions and detailed training analysis
- Music storage and support for streaming services
- Water resistance suitable for lap swimming
Cons:- Premium subscription required for music streaming
- Relatively high cost for a renewed device
Best for: Multisport athletes who want a combined training and music device capable of tracking swimming, running, and cycling in one watch.
Not ideal for: Beginners or casual users who do not need music storage or advanced multisport features, as the device might be more complex than necessary and costlier.
- Battery Life:Up to 1 week in smartwatch mode, 6 hours in GPS with music
- Water Resistance:Suitable for swimming
- Music Storage:Up to 500 songs
- Connectivity:Garmin Pay, compatible with music streaming
- Activity Profiles:Running, triathlon, multisport, cycling, pool swimming
Our verdict“This model is ideal for multisport enthusiasts who want a feature-rich device with music and swim tracking, though it may be more than needed for casual runners.”
Garmin Forerunner 55 GPS Running Watch with Daily Suggested Workouts
The Garmin Forerunner 55 offers simplicity combined with essential features, making it an excellent choice for newcomers who want basic GPS tracking, heart rate monitoring, and personalized workouts. Its long battery life ensures it can handle daily runs and swims without frequent charging, and the customizable watch faces add a personal touch. Compared with the more advanced 255, it lacks some performance metrics like HRV or adaptive training, but this simplicity is its strength for those starting out or seeking an easy-to-use device. However, its heart rate monitor isn’t medical-grade, and some features depend on a smartphone app, which might be a mild inconvenience for tech-averse users.
Pros:- Long battery life suitable for daily use
- Personalized training guidance and suggested workouts
- Advanced wellness metrics like respiration and activity monitoring
- Customizable with watch faces and apps
Cons:- Heart rate monitoring is not medically certified
- Some features require a smartphone app

Not ideal for: Advanced athletes or those seeking in-depth performance metrics, as it offers limited advanced features and customization.
- Battery Life:Up to 2 weeks in smartwatch mode; 20 hours in GPS mode
- Display Size:1.04 inch
- Compatible with Vehicle Type:Bicycle
Our verdict“This watch is best for entry-level runners and swimmers looking for straightforward tracking and fitness guidance without complexity.”
Garmin Forerunner 255 GPS Running Smartwatch, 46mm, Tidal Blue
The Garmin Forerunner 255 combines lightweight design with extensive health and training metrics, making it suitable for dedicated runners and swimmers who push their limits. Its long-lasting battery, with up to 14 days in smartwatch mode, supports long training sessions and races, while the detailed performance insights—like HRV, training status, and adaptive workouts—are superior to the Forerunner 165. The full-color always-on display enhances visibility during outdoor activities, but the need for optional accessories like HRM-Pro for advanced metrics could be a hurdle. Compared to the Forerunner 745, it offers a more affordable option with many core features, though less multi-sport flexibility.
Pros:- Long battery life for extended training and races
- Comprehensive health and performance metrics
- Customizable workouts and adaptive training plans
- Smart features like contactless payments and notifications
Cons:- Requires additional accessories for advanced metrics
- May be complex for users unfamiliar with detailed training analytics
Best for: Experienced runners and athletes seeking a durable, feature-rich watch for both running and lap swimming, with comprehensive metrics and long battery life.
Not ideal for: Beginners or casual athletes who do not require extensive training analytics or adaptive workouts, as the device can be complex and potentially overwhelming.
- Size:46 mm
- Display:Full-color, always-on
- Battery Life:Up to 14 days in smartwatch mode, 30 hours in GPS mode
- Activity Profiles:30+ including triathlon, cycling, swimming
- Connectivity:Garmin Pay, smartphone notifications
Our verdict“This watch is perfect for performance-focused runners and swimmers who want extensive data and durability for their training routines.”
COROS PACE 3 GPS Sport Watch, Lightweight Running Watch – Chalk Nylon
The COROS PACE 3 stands out for its excellent combination of lightweight comfort, extended battery life, and accurate dual-frequency GPS. Compared to the COROS PACE 4, it offers slightly less vibrant display but remains highly durable and versatile across activities like trail running, cycling, and swimming. Its long-lasting 38-hour GPS battery makes it ideal for multi-day training, but the limited color options and less readable display in bright sunlight may be drawbacks for some users. This pick makes the most sense for serious runners who value endurance and multi-sport support without sacrificing comfort.
Pros:- Lightweight and comfortable for all-day wear
- Long battery life suitable for extended training sessions
- Accurate GPS tracking even in urban environments
- Supports multiple activity modes with route planning
Cons:- Limited color options
- No built-in music storage
- Display may be hard to read in bright sunlight

- Battery Life:38 hours GPS, 24 days daily use
- GPS:Dual-Frequency
- Material:Nylon band
- Activity Modes:Run, trail run, bike, swim, strength, snowboard, ski, XC ski
Our verdict“This watch is best for serious runners and multi-sport athletes who prioritize endurance and versatility over display vibrancy.”
Smartwatch for Swimming with GPS and Heart Rate Monitoring
This waterproof smartwatch excels for swimming and outdoor activities with its advanced GPS, compass, and AI swim analysis, making it a strong choice over the COROS PACE 4 for swimmers who want detailed stroke analysis. While it offers a comprehensive health suite with sleep and heart rate monitoring, its compatibility may be limited with certain smartphones, and the complex features could require a learning curve. The battery life, while long-lasting, isn’t specified, which might concern users seeking ultra-long sessions. This model makes sense for serious swimmers wanting detailed performance insights and reliable waterproof design.
Pros:- Waterproof design suitable for swimming
- Advanced GPS and navigation features
- AI swim analysis for stroke improvement
- Continuous heart rate and sleep tracking
Cons:- Compatibility issues with some smartphones
- Battery life details are not specified

- GPS:Built-in
- Compass:Yes
- AI Swim Analysis:Yes
- Heart Rate Monitoring:Yes
- Sleep Monitoring:Yes
Our verdict“This watch is ideal for swimmers who want detailed performance analytics and reliable waterproofing, but less so for multi-sport enthusiasts seeking broader outdoor tracking.”
COROS PACE 4 Ultralight Sport GPS Watch (Black Silicone, Standard)
The COROS PACE 4 offers a vibrant 1.2-inch AMOLED display, making it more eye-catching than the Pace 3, especially in outdoor settings. Its long battery life—up to 41 hours in GPS mode—and features like voice control and customizable buttons make it a compelling choice for serious runners and fitness enthusiasts. However, its limited color options and slightly less responsive touchscreen during intense activities could be drawbacks for some users. Compared with the Pace 3, it provides a more engaging visual experience but at the cost of a slightly higher price and potentially less durability in rough conditions. This makes sense for athletes who want a sleek, feature-rich device with excellent display quality.
Pros:- Vibrant, high-resolution AMOLED display
- Long battery life with 41 hours GPS use
- Voice recording and control for quick commands
- Customizable action button for quick access
Cons:- Limited color options (only black)

- Display:1.2-inch AMOLED touchscreen
- Battery Life:Up to 19 days daily, 41 hours GPS

Our verdict“This pick is best for athletes who desire a sleek, high-res display with extensive training and health features, willing to accept some responsiveness tradeoffs.”
Mibro GS Pro2 GPS Running Smartwatch with Dual Band GPS, 48mm, Dark Gray
The Mibro GS Pro2 provides dual-band GPS for highly accurate route tracking, making it a reliable partner for outdoor runners and swimmers. Its support for over 150 sports modes and health metrics like SpO2 and heart rate make it a versatile option, especially compared to the more simplified options. The large 48mm display and water resistance up to 5ATM suit outdoor adventurers, but its bulkier size might be less comfortable for smaller wrists or casual users. While battery life extends up to 20 days, the absence of features like music storage or smartphone notifications limits its appeal for some users.

Pros:- Accurate dual-band GPS for precise route tracking
- Long battery life suitable for extended outdoor activities

How We Picked
To select the best running watches for lap swimming plus running, I focused on key factors that matter most to multisport athletes. Performance was evaluated based on GPS accuracy, swim tracking capabilities, and running metrics. Usability included ease of use, display clarity, and comfort during extended workouts. Build quality and battery life were also critical, especially for those training regularly across different environments. Devices were ranked according to how well they balanced these criteria, with an emphasis on versatility and value for both casual and serious athletes.Factors to Consider When Choosing Running Watch For Lap Swimming Plus Running
Choosing a running watch that also supports lap swimming requires careful consideration of several factors. Not all watches excel equally in both domains, so understanding what features truly matter can prevent costly mistakes. Durability, water resistance, and battery life are vital, but so are usability and data accuracy. Additionally, consider your training volume and whether you prefer a simpler interface or advanced analytics. These considerations will help you identify a watch that supports your full spectrum of workouts without compromise.Water Resistance and Durability
Since lap swimming involves frequent water immersion, selecting a watch with a high water resistance rating—ideally 5 ATM or greater—is essential. Durability in saltwater or chlorinated pools also matters, as materials should withstand corrosion and wear. Cheaper models might claim water resistance but often lack the robustness needed for regular pool use. Investing in a device with proven water resistance ensures your watch remains functional and accurate over time.
GPS and Swim Tracking Accuracy
Accurate GPS tracking impacts your outdoor runs, while precise swim metrics are crucial for pool workouts. Not all watches handle indoor swim tracking well; some rely on accelerometers that may be less accurate than dedicated pool sensors. For multisport use, look for watches with dual-band GPS and dedicated swim modes that record laps, strokes, and distance reliably. Inaccurate data can lead to misinterpreted progress, so it’s worth prioritizing models with proven tracking precision.
Battery Life
Multisport activities drain battery quickly, especially when GPS and heart rate monitoring are active simultaneously. Watches with longer battery life—typically over 24 hours in GPS mode—reduce the risk of running out mid-workout. Consider how often you train and whether you prefer a device that can last through multiple sessions without frequent charging. For extended outdoor swims or long runs, a device with extended battery endurance provides more peace of mind.
User Interface and Comfort
A watch’s interface should be intuitive, especially when switching between swim and run modes. A cluttered display or complex menus can hinder focus and slow down data review. Comfort is also key; lightweight, adjustable straps and a design that fits snugly without chafing support longer training sessions. Test the usability of controls and display readability in different lighting conditions to ensure a smooth experience during varied workouts.
Additional Features and Ecosystem Compatibility
Beyond basic tracking, features like heart rate monitoring, sleep analysis, and training plans add value. Compatibility with your smartphone ecosystem—whether Garmin Connect, Apple Health, or others—can streamline data synchronization and analysis. Consider whether you want features like music storage or contactless payments, which can enhance your overall experience. Weigh these extras against your core needs to avoid paying for unnecessary features that won’t be used regularly.
Frequently Asked Questions
Can I use a running watch for both open water swimming and lap swimming?
Many running watches are primarily designed for pool swimming, with indoor lap tracking and limited open water features. If you plan to swim in open water, look for watches that explicitly support open water modes, GPS accuracy in outdoor conditions, and longer battery life. Not all devices handle both well; some excel at pool laps but lack the outdoor swim features, so check specifications carefully based on your predominant swimming environment.
How important is GPS accuracy for my running and swimming workouts?
GPS accuracy significantly impacts outdoor running metrics, such as distance and pace. For swimming, especially open water, precise GPS ensures your routes and swim distances are correctly recorded. Poor GPS can lead to inconsistent data, making it harder to track progress. Devices with multi-band or dual-frequency GPS generally provide better accuracy, especially in challenging environments like dense urban areas or under heavy tree cover.
Will a cheaper running watch without advanced features suffice for lap swimming and running?
Basic models may track distance and time but often lack detailed swim analytics, stroke recognition, or multisport modes. If your training involves precise metrics, performance analysis, or structured workouts, cheaper options might fall short. However, for casual swimmers and runners, entry-level watches can provide sufficient data without the higher price tag. Consider your training goals carefully before opting for a budget model.
How does battery life affect multisport training in these watches?
Battery life is critical when engaging in extended multisport sessions, especially if you rely on continuous GPS and heart rate monitoring. Watches with limited battery capacity may require frequent charging, interrupting your routine or limiting session length. For long-distance workouts or multiple sessions per week, choosing a device with at least 24 hours of GPS endurance can keep your training seamless and uninterrupted.
Are there any compatibility issues between these watches and third-party fitness apps?
Most watches synchronize with their proprietary apps, like Garmin Connect or COROS App, which offer comprehensive data analysis. Compatibility with third-party apps varies; some watches integrate smoothly with popular platforms like Strava, TrainingPeaks, or Apple Health, while others may have limited options. Check the specific device’s app ecosystem to ensure it meets your preferred data management and analysis needs before purchase.
Conclusion
For serious multisport athletes focused on precision and advanced features, the Garmin Forerunner 955 stands out as the best overall choice. Budget-conscious runners and swimmers who want reliable basics will find the Garmin Forerunner 55 offers excellent value. If comfort and weight are your priorities, the COROS PACE 4 is ideal for extended multisport sessions. Beginners should start with simpler models, while experienced athletes can benefit from high-end options with extended battery life and detailed analytics. Your ideal watch depends on your training intensity, environment, and feature preferences—choose accordingly.
