Benefits of Using a Triathlon Watch
Keeping track of your fitness goals and training plays a significant role in your efficiency and overall performance for the triathlon, especially if it is your first time to participate in. There is a wide range of fitness trackers and devices alike that support this type of program.
However, some of these watches or devices fall short of the essential features and thus, can’t provide comprehensive data. That’s when triathlon watches take the spotlight; they are intricately programmed to provide vital details about the sport you’re engaging in and advanced performance metrics.

In addition, modern innovations also allow you to integrate your smartphone with your triathlon watch that enables smart notifications and music. Apart from the usual sports metrics, a tri watch can also track stress, sleep rate, number of calories burned, and number of steps.
Some triathletes also find the recovery time useful, a feature that can determine when you should go for a break and when you can push yourself hard again for another workout. This helps prevent injuries and muscle tension.

How to Choose the Best Triathlon Watch
Many modern designs of triathlon watches are programmed with a built-in GPS. It is an essential feature that helps athletes to track and locate directions, paths, and different courses and hence, allowing you to check and calculate your total distance, motion, and speed.

Some watches are based on satellites and therefore, provide global navigational guide while there are designs that are required to be integrated with a smartphone for it to fully function.
Connectivity
Wifi or Bluetooth connection can also be an advantage if you want to keep track of your notifications on the smartphone, particularly messages and calls. Some triathlon watches are also integrated with a Wifi connection where you can upload and share your performance metrics and progress to an exclusive online community and social media.
Device Compatibility
For triathlon watches that have smart features, it is important to know whether they are compatible with your device, such as smartphone, or not. Being able to integrate with your phone opens up a ton of advantages where you can get notified whenever you have new messages, mails or upcoming calls while training. It can also be useful for some watches that require a device connection to activate GPS.
If you want to enjoy working out and training while reveling in some good music, the teaming up with your device can provide synchronization to the music list on your phone. Some designs can even access and sync with your Spotify music playlist.
Performance Monitoring and Accuracy
Probably the most important feature you should never brush off and miss is the performance monitoring and accuracy. This includes the performance metrics for running, cycling, and swimming or other sports you’re engaged in. Triathlon watches that are programmed with activity profiles should have efficiency in this feature as well.

For an enhanced training program, many tri watches are engineered with advanced performance dynamics that efficiently track the distance, pace or speed, and time. Certain designs can even track your calories to make sure you’re getting the best out of your training.
You may also find heart rate sensors useful where you can monitor your heart rate at the wrist when working out or even swimming. You’ll be able to determine whether you’re in the good condition to go hard on your training and workouts or not.
Battery Life
Since you’ll be wearing it for long hours, it is best to settle on a tri watch that can ensure long-lasting battery life. Some can last for days or weeks before you can have them recharged. Other brands have exceptional battery life, although not rechargeable, that can last for years.
Training and Recovery Stats
Tracking your recovery stats helps you to get back on track after exhausting training. It evaluates your performance and activities 24/7 and helps you to recognize the value of taking breaks or rests in between training sessions.

You’ll also be able to know whether you’re overdoing a certain training or workout or you need to give it a little boost. In this way, you can prevent injuries and other health issues; you can feel fully rejuvenated for the next training.
Multisport Feature
It is the ability to switch between sport and activity profiles for the instant analysis of your performance during the race or while training. It is a useful feature during a triathlon that allows you to switch between swimming, cycling, and running without interrupting the current and previous readings and can be reviewed for later.
Waterproofing

Tracking your swimming metrics would be a whole lot easier if the tri watch is waterproof and it should be. You can use it efficiently on open waters or swimming pools to track your performance and progress.
Comfort
These triathlon wrist watches should be comfortable enough when worn. There are many designs that are structured with a stainless steel frame and durable bands to ensure a quality that can last for years. But no matter what design you opt for, make sure it doesn’t feel too tight or too loose but rather snug and comfortable on your wrist when you run, swim, or whatever activities you have to do.
Quick Release Bands
Quick release bands allow the watch to easily detach from its strap so you can mount it on a handlebar and view your readings easily while cycling or biking. Catching up on your readings and viewing them from time to time while the watch is worn on your wrist can be pretty difficult and dangerous. That’s why many prefer the quick release feature, although this can only be available on specific models.
Frequently Asked Questions
What are the essential features of a triathlon watch?
The GPS, fitness tracker or the performance metrics (swimming, running, cycling), and waterproofing are probably the essential features your tri watch should have. You need a GPS or navigational aid to track your routes or locations while the fitness tracker keeps tabs on your performance metrics such as speed, distance, pace, and time; these are very important.
But, of course, every design has its respective features and it all depends on your preference on which features you should settle for. Some may find smart notifications, heart rate sensor, Wifi connection, and device compatibility advanced but significant in their training.
What is the battery life of a triathlon watch?
It actually depends on the brand, but the average design should have at least a few days before it wears out and be up for recharging. There are units that have rechargeable batteries, but other brands have great battery life and can only be replaced after many years of use.
How much do they usually cost? Are they expensive?
The basic designs usually cost around $100 and below while those that have smart and advanced features come with a higher cost. It can be as cheap as $150 and as expensive as $800. Sometimes, they cost a lot higher due to the brand and additional features.
What are the differences between a triathlon watch and a running watch?
A running watch is basically about running metrics. It is programmed with a sole purpose – to measure and track your progress and stats in running such as distance, pace, and time. On the other hand, a triathlon watch provides performance metrics for three major triathlon sports – running, cycling, and swimming.
In addition, a running watch can either be waterproof or not while triathlon watches are and should be waterproof as swimming is a major part of the sport.
Wrapping It Up
When it comes down to choosing the best triathlon watch, it truly is a tough call. The watches mentioned on the list have their respective features that can make a reliable fitness buddy and triathlon coach. But with all these amazing picks, I found the Garmin Fenix 5 the best among the others.
I was actually contemplating between the Fenix 5 and Forerunner 935, but I’ve noticed that gap is just by a hair. They have exceptional battery life, in-depth navigational guide, and track the progress and performance metrics for triathlon efficiently and right on the dot. The only significant difference is probably the weight. Forerunner 935 is much lighter.
However, Fenix 5 is much more affordable but you can already take advantage of its smart features and advanced training programs. On the other hand, you can also pick out the watch that suits your preferences and needs. Just take note of the vital features so you can efficiently keep track of your training and workouts.
