3 Best Garmin Watches For Duathlon:

As all these watches are from the same company, their features more and less overlap. Therefore, we are going to explain the first watch (Garmin Forerunner 945) in detail and would discuss the other two briefly, only explaining their key advantages over FR945.

  • Sensors: Garmin Elevate heart rate sensor, GPS, GLONASS Galileo, Barometric altimeter, Compass, Gyroscope Accelerometer, Thermometer, Pulse OX blood oxygen saturation monitor

Garmin Fenix 7 is the latest watch from the company and the most expensive on our list. Almost all its performance and health metrics overlap with FR 945, but there are a few domains in which Fenix 7 has a considerable advantage.

First, it has a bigger, sharper, and touch-enabled screen. The watch offers better battery life and has a Solar variant that can last for even months on a single charge.

Also, it packs a new Elevate sensor and a refined algorithm, which further gives it an edge over FR 945 in terms of heart rate and other health metrics tracking. Lastly, it offers more activity profiles in case you want to do more than the duathlon this summer.

On the other hand, an expensive price tag and heavy build of the watch might be a turn-off for competitive athletes.

Garmin Forerunner 245 Music:

Garmin Forerunner 245 Music:

Check Amazon Price

  • Price Range: Around $300
  • Weight & Size: 42.3 x 42.3 x 12.2 (mm), 38.5 g
  • Display: 1.2 inches, sunlight-visible, transflective memory-in-pixel (MIP), 240 x 240 pixels
  • Companion App: Garmin ConnectIQ
  • Advanced Performance Metrics: Yes
  • Health and Fitness Metrics: Yes
  • Multisports Tracking: Yes
  • Music Storage: up to 500 songs
  • Battery Performance: Up to 7 days | GPS mode with music: Up to 6 hours | GPS mode without music: Up to 24 hours
  • Sensors: GPS, GLONASS, Galileo, Garmin, Elevate heart rate sensor, Compass, Accelerometer, Pulse ox, Thermometer

Garmin Forerunner 245 Music is an affordable alternative to its successor, and it is about 12 grams lighter in weight.

It covers almost all the running metrics that you get in its big brother except for features like Lactate Threshold and Stress Score. But the story is entirely different when it comes to tracking the important cycling metrics. It doesn’t connect to the power meter so doesn’t track wattage and associated data. Even the speed and cadence data are not available unless you connect it with external sensors.

In the health and fitness tracking department, there is little difference between FR245 and FR945.

Also, there is storage for music on the watch itself. You can download playlists from Spotify, Amazon Music, or Deezer or upload good old mp3 songs through your pc or phone. However, there is no NFC payment feature on this watch which is truly a disappointment for a mid-range smartwatch.

The battery life is really good and can last up to 7 days on a single charge. However, if you use it for GPS tracking and music playback, that number will be reduced to 6 hours.

What to Look for in a Garmin Watch for Duathlon?

There are a few key things that you’ll want to look for in a Garmin watch specifically designed for duathlon:

Weight and Build Quality: As with any piece of sports equipment, you’ll want to choose a watch that is both lightweight and durable. The last thing you want is a watch that feels bulky and cumbersome when you’re trying to focus on your training.

Advanced Performance Metrics: One of the main reasons to invest in a Garmin watch is for the advanced metrics. Its high-end watches are packed with sensors that track everything from your Stress Score, Heart Rate Zones to Training effects and Status, and this data can be extremely useful as it provides you with valuable insight into improving your performance and helps you up to your game.

Health and Fitness Tracking: In addition to tracking your performance metrics, a good Garmin watch should also track all of your health and fitness data. This includes everything from your steps taken, calories burned, and sleep quality to your Vo2 Max and recovery time.

Multi-Sport Support: As the name suggests, duathlon involves two different sports, so it’s important to choose a watch that supports both running and cycling. Some of the higher-end Garmin watches also support swimming, so if you want to use your watch for triathlon training as well, this is something to keep in mind.

Music Storage & Contactless Payment: Training for a duathlon can be pretty demanding, so it’s nice to have some music to keep you going. A few of the higher-end Garmin watches come with storage for up to 500 songs, which is perfect for those long training rides and runs. Also, if the watch has contactless payment (Garmin Pay), it would save you the trouble to keep your wallet with you all the time.

Battery Performance: Generally, ****Garmin watches are good when it comes to battery life. However, as plan to use your watch for multi-sport training, you may need to factor in extra battery life (at least 24 hours with continuous GPS tracking) to cover the added wear and tear.
