What to Look for in the Best Triathlon Watch
When it comes to finding the best triathlon watch, there are certain criteria that need to be met. Keep in mind that triathlon involves three different activities and your triathlon watch should be able to accommodate each one. We’ve listed down some things to consider when determining the best triathlon watch for you.
One of the three portions of the triathlon is swimming. So, naturally, you should pick a watch with adequate water-resistance. For swimming, you’ll need to have at least 100 metres of water-resistance. Fifty meters may be enough for taking showers but it won’t do well when swimming. On the other hand, 200m is typically meant for dive watches, and since you won’t be doing any diving in a triathlon, having such a level of water-resistance isn’t really necessary.
2. Battery Life
Triathlons often take several hours to finish. You absolutely cannot have your triathlon watch die on you in the middle of the race. The best triathlon watch would have long and reliable battery life. This is important especially if you’re training in unfamiliar terrain. Imagine going on a run on an unfamiliar route and having your battery be drained. You won’t be able to access the GPS or any other helpful function your triathlon watch has to offer. Having a watch with a longer battery life makes you feel more reassured. But, either way, it’s important to have a fully-charged watch before your triathlon.
Often, we look for the coolest features when it comes to the best triathlon watch. But always consider the watch’s durability first. You wouldn’t want your watch falling apart while you’re in the race. Having a high-tech watch would be of no use if you just end up losing it in the water because the strap fell apart as you were swimming. That definitely would suck. You also have to consider the lens. You don’t want a watch that gets easily scratched up. A lot of things happen during a triathlon and at some point, you might accidentally hit your watch on something. Having a scratched or cracked lens would just make it harder for you to read your watch. So, the best triathlon watch would have to be one that’s made with durable materials.
Comfort is often overlooked compared to the other aspects but it is just as important. Having a watch that digs into your skin or just doesn’t fit you right would make it hard to focus throughout the triathlon. It’ll just bother you to no end and would no doubt affect your performance. When searching for the best triathlon watch, don’t just rely on the reviews. It could be the best triathlon watch in the market, but if it doesn’t fit you right it’ll only be a hindrance instead of an asset. Try it on first and see how it feels and how it fits your wrist.
5. Multisport Function
The amazing thing about technology is how it makes things a lot more convenient for us. The multisport function in a lot of smartwatches definitely changes the game. It gives you so much information and even helps you process this info to let you know how you should proceed. The best triathlon watch should have specific functions that cater to running, cycling, and swimming. Being able to monitor your progress in these areas will really help you improve and set the right goals. You’ll come out a better athlete if you know how to maximise these tools. And, of course, you have to consider the ease of transition between modes when you’re in the middle of the race. Every second counts and you simply cannot stop just to configure your watch. The quicker and easier the transition, the better.
We may have put out our suggestions for the best triathlon watch, but in the end, the choice is up to you. Go for the watch that feels right for you. And we mean this literally because comfort and fit are crucial. Pick the watch that would cater to your particular needs. This could either be a smartwatch or a classic digital watch. The key is how you decide to utilise these tools for your own benefit.
