Triathlon Watch Shopping Consumer Guide

Shopping for a triathlon watch involves dissecting two main questions that most consumers have in mind when going triathlon shopping.

What Design Features Constitute A Great Triathlon Watch?

There are many features you need to consider before purchasing a triathlon watch that meets your specifications. However, the most common features that the majority of consumers desire are:

A GPS Navigation System

A cardio-intensive event like a triathlon requires a reliable GPS navigation system to track your progress through and through.

Indeed, navigation is ideal because it helps you keep in tune with your bearings as you conserve your energy.

Expending too much energy in some sections of the race might prompt an early exit for you.

Hence, a triathlon watch with a modern navigation system plays a vital role in completing the event successfully.

Durability and Water Resistance

During a triathlon, you will be pushed beyond your limits while tackling tough and challenging terrain.

As such, you must have a sturdy triathlon watch that can withstand all types of pressure; whether on land or at sea.

Indeed, a robust and water-resistant watch can be all the difference between seamless navigation and prematurely checking out of the race due to strategic failure.

Such a sturdy watch usually has a robust bezel with protective features such as anti-glare, scratch resistance, and water resistance.

This is to ensure longevity as you participate in as many triathlons as possible.

Battery Life

A standard triathlon takes up to 12 hours to complete and consists typically of swimming, running, and cycling.

Hence, you will need a handy triathlon watch that carries extensive battery life with just one charge.

As a safeguard, always buy a watch that emphasizes long battery life, especially when several of its features such as the heart-rate monitor and GPS are activated simultaneously.

With that said, you have to be careful with some smart triathlon watches that exhibit a significant battery drain when many apps are used at the same time.

Compatibility with Triathlon Apps

If you decide to purchase a smart triathlon watch, make sure it has functional connectivity with third-party workout apps.

These apps can prove indispensable during triathlon events as they help you navigate and monitor your vitals in some of the most tiring stages of a triathlon.

What Factors of the Watch Should I Consider Before Purchasing It?

Features of the watch, such as GPS tracking and pulse-monitoring, are not the only essentials to analyze before purchasing a triathlon watch. Indeed, it is important to analyze subtle factors such as the brand and price of the watch before buying it.


When it comes to brand, we must hone in on quality. How does brand X edge out brand Y to become the apex triathlon watch provider in the market? To answer this, we will analyze the design and manufacturing process that goes into creating every triathlon watch.

For example, what kind of material is used? Or how sturdy is the watch? Indeed, each brand usually provides a detailed review of the tensile and pressure tests that their training watches have been subjected to. Such information can be found on the company’s main website.

While it is understandable to have your preference, it won’t cost an arm or a leg to have an open mind when searching for the best quality watches in the market.

Don’t merely select a particular brand just because it sounds cool, or you have a sentimental attachment to it. Check out brands that have a genuine mark of quality on them, or are respected even by their rivals.


A dime in a dozen (as the phrase dictates) might seem scarce during triathlon watch shopping, especially if you’re sacrificing some features for affordable pricing. But that doesn’t mean it’s impossible.

You can still get a durable, capable triathlon watch without murdering your wallet. Indeed, you will find that some of the best triathlon watches in this list are pocket-friendly and can save you a dollar for a rainy day!

And The Winner Is…

Whether this is your first or one-hundredth triathlon, you’ll find that the Garmin Forerunner 935 is a great companion to have by your side. Not only does it have a state-of-the-art GPS navigation system, but also provides a seamless connection to third-party apps and accessories. The 935 can be used for any training activity, and its lightweight design makes it a comfortable watch to have as you push your body to the limit!
