Features to Consider
Here are some features to consider when selecting the best Garmin watch for triathlons.
GPS & Mapping Features
Not every Garmin watch has advanced GPS and mapping features. If you opt for a watch with these features, the price will rise significantly. However, these features are well worth the money because they give you valuable information, allowing you to focus on what matters.
Performance Tracking Features
While most Garmin watches will give you performance tracking features, like VO2 Max, training status, and basic performance metrics, some features like advanced running dynamics may require purchasing separate devices.
Always make sure the watch has the performance tracking features you want before selecting.
Luxury Features
Not everyone needs music for training and competing, and if you aren’t big on music, opt for a watch without music features to save money and battery life. Moreover, features like Garmin Pay and a premium or stylish design do not matter for triathlons and can be compromised to save money.
That being said, all Garmin watches have the basic smartwatch and connectivity features that make them great for everyday use.
Battery Life
Triathlon training and competing using the full features of your watch will drain the battery very quickly. You may want to consider battery life with features like GPS, performance tracking, and music in use. The better the battery life, the more you can get out of your Garmin watch.
Our Final Thoughts
Garmin makes excellent multisport smartwatches that give triathletes the performance tracking they need and more. You cannot go wrong with any of the watches mentioned in this post, and your choice should depend on your feature preferences.
If we had to choose, we would pick the Garmin Forerunner 245 Music as it’s the best budget pick for triathletes who want the most value for their money in terms of relevant features and don’t mind compromising on style.
Still, the Garmin Forerunner 945 is hands down the best Garmin watch for triathlons because of its full-range performance tracking, GPS, and mapping capabilities. Moreover, its Garmin Pay, music features, long-lasting battery life, and premium design make it excellent for everyday use as well.
