The apple watch series 5 running question comes up often for runners who already own an iPhone and want to skip a dedicated sports watch. The Series 5 still tracks pace, distance, heart rate and workouts well enough for everyday training, but its battery life, lack of newer health sensors and aging software support make it a weaker choice than current Apple models or Garmin watches for serious racing. If you want a basic, phone-connected running tracker and already have the watch, it is a reasonable tool. If you are buying a watch mainly for structured training, it is worth looking at alternatives.
| Criterion | Apple Watch Series 5 | Garmin running watch (typical mid-range model) |
|---|---|---|
| GPS for outdoor runs | Built-in GPS, reasonable on open roads | Multi-band or dual-frequency GPS on higher models, strong in tree cover |
| Heart rate tracking | Optical sensor, adequate for steady runs | Optical sensor, often paired with chest strap support |
| Battery life in GPS mode | Short, usually a day of active use with charging | Commonly one to several weeks in watch mode, many hours of GPS |
| Running metrics | Pace, distance, splits, basic heart rate zones | Training load, recovery time, race predictor, cadence and more |
| Phone dependence | Works best with an iPhone | Works with iOS and Android |
| Water resistance | Suitable for swimming and sweaty runs | Suitable for swimming and sweaty runs |
GPS Accuracy: Which Holds a Better Route?
For outdoor running, GPS accuracy decides whether your distance and pace numbers can be trusted. The Series 5 includes built-in GPS, and in open areas it generally logs distances close to a marked course. Under tree cover, near tall buildings or on winding trails, single-band GPS can drift, so you may see a slightly longer distance than you actually ran.
Garmin running watches, particularly models that advertise multi-band satellite support, are designed to hold a tighter track in those conditions. Owners often report smoother pace readings in urban canyons and wooded routes.
Winner: Garmin. For road running in open terrain, the Series 5 is adequate. For trail runs and city routes with heavy interference, the Garmin takes the lead.
Heart Rate Monitoring: Which Reads Your Effort More Reliably?
Both options use optical heart rate sensors on the back of the watch. The Series 5 gives you steady readings during easy runs and useful zone data for general fitness. Optical sensors can lag during rapid pace changes, intervals or cold weather, and a fitted strap can make the reading more stable.
Many Garmin users pair their watch with a chest strap for interval sessions, and the Series 5 can also connect to compatible chest straps through third-party apps. Still, out of the box, the Garmin’s heart rate data and recovery insights are more developed.
Winner: Garmin, mainly because of its training-focused analysis. The Series 5 is fine for keeping an eye on effort during easy and moderate runs.
Battery Life: Which Lasts Through Your Long Runs?
Battery life is where the Series 5 shows its age most clearly. Apple rates the watch for roughly a full day of mixed use, and GPS workouts drain it faster. A long run with GPS active, plus a few hours of notifications, can leave you needing a charge before bed. If you run early in the morning and want to wear the watch all day, plan to charge it during the night.
Garmin running watches are built around long battery life. Many models offer days of smartwatch use and many hours of GPS tracking, which means you can do ultramarathon-length training or multi-day trips without carrying a charger.
Winner: Garmin, by a wide margin for endurance training and travel.
Training Features: Which Gives You More to Work With?
The Series 5 tracks workouts, rings for activity goals, and gives pace, split and heart rate data after each run. It works well for runners who want a simple record of their sessions. It does not offer the same depth of training guidance found on dedicated running watches.
Garmin watches typically include training load scores, recovery advice, race time predictions, and structured workout builders. Runners training for a specific event can load intervals and follow them on the wrist. The analysis tools also help you spot when you are overtraining.
Winner: Garmin. If you are following a training plan, Garmin’s features are a better fit. If you mainly want to log runs and check your numbers, the Series 5 covers the basics.
Ecosystem and Phone Compatibility: Which Fits Your Setup?
The Series 5 is built for iPhone users. It pairs with the Health app, syncs workouts to Apple Fitness and works with many third-party running apps that read Apple Health data. If you already use an iPhone, the setup is smooth and the notifications feel native.
Garmin watches work with both iOS and Android phones and sync to Garmin Connect. For runners who switch between phones or who use Android, that flexibility is a clear advantage.
Winner: Depends on your phone. iPhone owners get a tighter experience with the Series 5. Android users should look at Garmin or another cross-platform option.
Software Support and Longevity: Which Will Stay Current?
Apple has moved its watch software forward every year, and older models eventually stop receiving the newest watchOS features. The Series 5 can run recent watchOS versions, but some new health and fitness features have been limited to newer hardware. Expect fewer updates over time compared with the latest models.
Garmin supports many of its running watches with software updates for several years, though feature rollouts vary by model. Check the specific model’s update history before buying a used watch.
Winner: Garmin, for steadier long-term feature support on comparable models.
Comfort and Wearability: Which Sits Better on a Run?
The Series 5 is light and has a slim profile that suits runners who prefer a low-profile watch. The default sport band is breathable and comfortable for most wrist sizes. Third-party sport loops and nylon bands are popular with runners who sweat heavily, since they dry faster and hold position well.
Garmin running watches come in several case sizes and strap styles. Many runners find them comfortable for long sessions, and some models are noticeably bulkier, so fit matters more.
Winner: Tie. Both can be comfortable. Choose based on your wrist size and whether you want a smaller or larger screen.
Which Should You Choose?
- Choose the Apple Watch Series 5 if you already own it, use an iPhone, run mostly short to moderate distances on roads and want basic pace and heart rate tracking.
- Choose the Apple Watch Series 5 if you want a watch that doubles as a daily smartwatch with notifications, payments and messages.
- Choose a Garmin running watch if you train for races, follow structured plans or need reliable GPS on trails and in cities.
- Choose a Garmin running watch if you run long distances and want battery life that lasts multiple days or longer.
- Choose a Garmin running watch if you use an Android phone or switch between phone platforms.
- Consider a newer Apple Watch model if you want Apple’s ecosystem with updated sensors and longer software support.

FAQ
Is the Apple Watch Series 5 good for running?
Yes, for basic running. It records distance, pace, splits and heart rate, and its GPS is adequate on open roads. Runners who want advanced training analysis or long battery life will find it limited.
Does the Series 5 track running accurately?
In open areas, its distance and pace are generally reasonable. Tree cover, tall buildings and trails can introduce drift, so compare it against a known course if accuracy matters for your training.
How long does the battery last on a run with GPS?
Battery life depends on conditions, screen brightness and notifications. Plan for a few hours of GPS workouts before charging, and check your own results over several runs.
Can I use the Series 5 with an Android phone?
No. The Series 5 is designed to pair with an iPhone. Android users should consider a cross-platform running watch.
Should I upgrade from the Series 5 for running?
If your watch meets your needs, there is no urgent reason to upgrade. Runners who want longer battery life, better training metrics or updated sensors should compare newer Apple models or Garmin watches before deciding.
Conclusion
The apple watch series 5 running experience is solid for casual and moderate training, especially for iPhone owners who want a single watch for daily life and workouts. Its battery life, limited training analysis and aging software support are real drawbacks for serious runners. If you train for races, run on trails or need long battery life, a dedicated Garmin running watch is the stronger choice. If you already own the Series 5, use it confidently for everyday runs and keep an eye on distance accuracy and charging habits.
