Things To Consider Before You Buy A Triathlon Watch

Good triathlon watches are quite expensive, so it’s important to make a smart decision before you spend your money. You have to consider things like battery life, the ruggedness of the watch, whether it is water-resistant, and so on. Here are the most important factors you should take into account before you choose which triathlon watch to buy.

1. Battery Life

It’s a good idea to get a watch with sufficient battery life that is longer than your daily exercise routine. That way you’re making sure it won’t die in the middle of your workout.

Battery life is particularly important when it comes to races because a triathlon race can last for many hours and you don’t want a watch that will die on your wrist after a couple of hours. A good triathlon watch should be able to last at least 6-8 hours in GPS mode. There are some watches that can last up to 120 hours in GPS mode!

2. Fit And Comfort

In a race that lasts for many hours, the last thing you want is to feel uncomfortable or to have to adjust the watch on your wrist every two minutes. In order to achieve a comfortable fit, make sure that you choose a triathlon watch that has a flexible silicone strap and a smooth case material.

3. Ruggedness

When you consider how much a triathlon watch costs, it’s normal to expect that it will be able to go the distance and not break easily. In other words, high-quality and toughness should be guaranteed. You don’t want your watch to break after accidentally falling off your wrist or after bumping it into your bike’s handlebar, so make sure that the watch you choose was build to last and can withstand anything.

4. Water Resistance

Every triathlon GPS watch should be waterproof, but that’s not enough. A triathlon watch is of no use if it is water-resistant but will not do or achieve much underwater. A good watch should be able to track the distance, show all the swimming metrics and some high-end watches can even monitor the pool laps, count your strokes and show you the type of stroke you are using. So, if you want to track swimming you should get a triathlon watch with an ATM rating of a depth of at least 50 meters. Some watches can go up to 100 meters!

5. Multisport Feature

This is a crucial factor to consider in a triathlon watch. A watch that has a multisport transition feature will allow you to easily switch modes with a push of a button. When you switch from running to cycling or swimming, it should mark a split in time as it transitions, so, later on, you can review the information. The display should also change to fit the mode you chose, for example from miles an hour to miles a minute when you switch from cycling to running.

If a watch doesn’t have this multisport transition feature, it will waste a lot of your time and you will lose the ability to review the whole workout as a single activity.

6. Quick-release

A quick-release feature is particularly helpful for those who want to move the watch from their wrist to their bike and its importance depends entirely on your needs. Not all watches have this feature, so if it is important to you, make sure to check whether the watch you chose has it.

7. Connectivity With Workout Accessories

Compatibility with other workout accessories can be very convenient and it’s something you shouldn’t pass on. A good triathlon watch should be compatible with heart rate monitors, speed sensors and so on. Some watches have Bluetooth sensors heart rate monitors that can work with devices like smartphones and tablets.
