The top smartwatches for running combine fitness tracking with notifications, music, texts, apps, and all the other great things you expect from a smartwatch.

1. Fitbit Versa 3

One of the newer Fitbits on the market, the Versa 3 combines fitness tracking with smartphone features. It’s versatile enough to take for a run, but has a stylish look for everyday wear.

It comes with a great battery that can last about 6 days. It charges from zero to 100% in a couple of hours.

The watch also provides 24/7 wrist-based heart rate monitoring. Leave your phone and music app at home while you listen to the 300+ songs it can store internally. There are also many apps available for download, including coaching, guided breathing, and reminders.

The Versa 3 is slimmer than older Fitbits. It has a square shape, similar to the Apple watch, and comes in various colors including pink, gray, and black. Plus, you can pair it with a range of different wristbands to customize your style.

The touchscreen makes using the watch simple. One button on the side are customizable to jump to the programs you use most. The screen is easy to read thanks to is a high-resolution AMOLED display.

Like many smartwatches, the Versa 3 performs best when synced with a smartphone. This means having your phone nearby. But, you can receive smartphone notifications. With an Android phone, you can “quick reply” to texts with a button push.

GPS has been included in this watch, so you can accurately track and record your runs and outdoor activities.

It supports 15+ exercise modes so no matter what you’re doing, you can track your progress. And, the Versa 3 is waterproof for swimming, able to track time and laps while in a pool.

Like all Fitbits, this one monitors steps, creates step goals, and monitors sleep. It also tracks calories burned and lets you compare active minutes vs. stationary minutes.

For an affordable price, this is one of the best watches out there for tracking your running and fitness progress.


  • Take it swimming – waterproof to 50m
  • Long battery life (~6 days)
  • Receives phone notifications (plus a “quick reply” with Android phones)
  • GPS and FitPay for contactless payments


  • Not as robuts for running as other watches

2. Apple Watch Series 6

The Apple Watch Series 6 – like version 5 – is an ideal smartwatch for runners.

The Series 6 comes with built-in GPS for tracking time, pace, and distance while running, meaning you can leave your phone at home. Easily see lap splits, cadence, and how far ahead or behind you are from your goal pace.

Waterproof to 50m, the Series 6 tracks both pool and open water swims. And if you don’t feel like setting the watch ahead of working out, it attempts to figure out and record whatever you are doing.

Enjoy listening to music? Stream music, podcasts, or radio stations from the watch to wireless Bluetooth headphones.

The display screen features an “always-on” function. This basically lets you see time and other basic data all the time without having to raise your arm. Battery remains the same as the Series 5 – about 18 hours. While you’ll likely want to charge it every day, it should last the entire day without a recharge.

The Series 6 tracks your activity 24 hours a day. It uses 3 activity rings that measure how much you move, how much you exercise, and how often you stand. Tracking these metrics ensures you are staying active throughout the day.

Heart rate is tracked with a wrist-based monitor. Going beyond simple pulse monitoring, a new ECG sensor displays irregular heartbeat patterns.

Any gym equipment that is compatible syncs with the watch to ensure accurate records of your speed, calories, and heart rate. With the ability to download many popular apps, you can use your favorites for working out.

The Apple Series 6 Watch is not your classic dedicated work-out device. But it does a great job tracking runs, ideal for weekend warriors.

It’s a great choice for any runner wanting an attractive yet fitness-ready smartwatch.


  • Built-in GPS and altimeter
  • Waterproof to 50m
  • Bright, crisp display


  • Short battery life (a little more than one day)

3. Samsung Gear Sport

We considered updating this watch for a more current model. But frankly, this is still the best Samsung smartwatch for running. And it’s sitting on sale right now at a nice price.

The Gear Sport is lighter and nicer looking than its older models, though heavier than many models on the market today. But it looks like a traditional watch, which is appealing to many people.

Choose between the black or the blue model, with a variety of interchangeable straps. It can run with both Android and iOS to check notifications, but is better suited for Samsung Android phones. When paired, you can utilize Samsung Pay and reply to texts when connected via Bluetooth (or Wi-Fi).

With an additional rotating wheel around the watch face, it is very easy to navigate menus. It boasts over three days of battery life, but the voice recognition is currently sub-par and there aren’t many apps to choose from.

What apps there are tend to be very good. Using the training guide app, there are more than 60 workouts to choose from, and the watch will guide you through each. The Gear Sport will continuously monitor your heart rate, and like Fitbit, will suggest various stretches if you’ve been sitting for a while. It is also waterproof to 50m, with a separate swim tracking app for more advanced stats.

It can automatically detect workouts, and your fitness data syncs with the Samsung S Health app. Strava, MapMyRun, MyFitnessPal, and a few other, lesser-known apps may be used as well. While it has a GPS, some features may not be as accurate as some individuals would like, so this watch is probably better suited for casual exercise.


  • Built-in GPS, altimeter and barometer
  • Attractive watch-like design
  • Waterproof to 50m
  • Easy interface
  • Track calories right from the watch without an extra app


  • Few apps
  • Voice command capability is not reliable
  • Some issues when pairing with a non-Samsung phone
  • Occasionally may freeze during exercise

4. LG Watch Sport

The LG Watch Sport is a good option for runners who want to stay connected but who don’t want to run with a phone. For an additional fee, it can work as its own phone, so you can make calls and workout without taking your phone along. Plus, there is now a keyboard that allows full texting.

The battery life isn’t the best, and the watch is rather large (not great for small wrists), but it still has a nice design and is comfortable. Verizon is no longer selling it, but it can be found elsewhere.

Waterproof up to just 1.5m for 30 minutes, this model is not advised for swimming. You can choose between titanium or blue, but there aren’t replacement wrist bands, since antennas are built into it. With its large size, (partially due to the built-in SIM card tray and 4GB of storage for music) it’s generally thought to be more for fitness than style.

There aren’t too many apps available either, but what is available can be installed from the watch in the mini app store. For the best functionality, having an Android phone will get you farther, especially if you want to use Google Assistant and Android Pay.

One nice feature besides the other fitness abilities is its strength training mode. Accuracy with location, pace and heart rate while running are decent, based on user reports.


  • Built-in GPS for runs, hikes and walks
  • Large display
  • Rotating dial to more easily navigate menus


  • Short battery life (little more than one day)
  • Large and heavy, better for fitness than style

5. Garmin vivoactive 4 (pictured) and 4S

This watch is one of Garmin’s first to bring a more attractive, round and lightweight design to the table – so comfortable you can forget you’re wearing it, even while running. Battery life in smartwatch mode runs over 8 days, and the GPS + music mode lasts up to 6 hours. Plus, it’s water-resistant up to 50m.

The vivoactive 4 comes in two sizes: the 4 and 4S. The 4 is more like the last version of the vivoactive in terms of size. While the 4S is less big, ideal for runners with small wrists.

The vivoactive 4 comes with one of the most accurate wrist heart rate monitors. It also measures stress and recovery. Plus, it will give you motivational messages and remind you when you’re not being active.

While this is simpler for style, it comes with many more built-in workout features such as preloaded running and swimming profiles (including stroke type detection and swim efficiency) and various GPS based workouts, though it is limited when it comes to strength training.

It features 15 sport profiles for a wide variety of exercises, from running to golfing, snowboarding and paddleboarding to rowing and yoga.

For runners, the vivoactive 4/4S tracks your cardio fitness level over time to give you an idea of how fit you are. Plus, you can compare to others in your age group with the app. It also features all-day stress tracking, which is something other watches have yet to incorporate.

Other nice features include an upgraded processor for faster response time and find-my-phone. You can also use mobile pay and receive smartphone notifications while on the go – calls, texts, calendar reminders and other apps as you set them – plus send basic responses to texts on Android phones.

New to the vivoactive 4 are built-in music storage and playback control. It also comes with emergency assistance. Push a button to alert friends/family of your location in emergencies. Auto-incident detection does the same thing if you crash on a bike.

There aren’t too many advanced performance metrics, but the price point is fair in comparison. If you’re looking for a fitness-focused watch to get into better shape, the vivoactive 4/4S is a solid option.


  • Built-in GPS, barometric altimeter, and thermometer
  • Long battery life
  • Mobile pay
  • Built-in music control and storage


  • Suited for fitness with fewer smartwatch “extras”

Garmin Venu

Garmin’s Venu is the same watch as the vivoactive 4/4S but with an AMOLED screen for a super hi-res display. In regards to features and functions, these watches are exactly the same. But you pay for the nicer screen in a literal sense, as the watch does cost more. The battery doesn’t last as long between charges, either.

6. Fitbit Sense

The Fitbit Sense is a bigger version of the Versa, with more features, a larger price tag, and a slightly bulkier, style made from aerospace-grade aluminum. The battery will last about 7 days, with the GPS battery life of 12 hours, and a short one-to-two hour charge time.

Added features: a variety of colors, replaceable bands, special tracking for female health, high-res screen, 300 songs storage, mobile payments, and access to Pandora.

The Sense functions as a classic Fitbit and has many smartwatch features that make it stand out. You can now install apps with the Fitbit operating system. The method Fitbit used to create this watch, combining plastic and metal into one continuous piece, is supposed to improve accuracy of the Wi-Fi antenna, GPS, and other sensors, which is great news for runners.

The heart rate monitor can help notice irregular heartbeat. There is also a SpO2 sensor which can be used for spotting sleep apnea and monitoring blood oxygen levels in the future. Other sensors include EDA to manage stress and a thermometer to track skin temperature.

There’s now an automatic activity pause, so if you stop at a stoplight, the watch pauses your exercise and resumes it when you start moving again. If you’re working out at home, there are three built-in workouts just for that. On runs, the Ionic automatically records all the stats you’d look for, and it’s pretty comparable to the Apple Watch.

When tracking sleep, it will tell you how much light, deep and REM sleep you had, as well as awake time.

The Fitbit Sense is great as a wrist-based fitness-tracking solution. Plus, it’s comfortable enough to wear all the time.


  • Built-in GPS and altimeter
  • Water resistant to 50m
  • Long battery life for the smartwatch (GPS use drains it to 10 hours)


  • Old design style
  • No speaker or microphone
  • Receive phone notification but you can’t reply
