Triathlon Watch Buying Guide & FAQs
How We Chose Our Selection of Triathlon Watches
Finding the best triathlon watch involved looking at four key features only the top of the range products offered.
Price - Good value triathlon watches may seem scarce without missing out on top-of-the-range features you’ve convinced yourself you need. That isn’t the case, though, and you can still get an effective triathlon watch without breaking the bank. We’ve tried to select a range of watches that are affordable for everyone from experienced triathlon athletes to those just getting into it.
Reviews - Checking out triathlon watch reviews proved massively useful when making our selection. This is because we don’t (always) have the time to try out these watches while training for our own triathlon. Instead, we look at the massive amount of reviews from people who have been there, done that (and probably gotten a t-shirt or two).
What’s also useful is their prior experience with other watches. Their well-rounded knowledge of the difference between certain watch types helps us to put together a well-informed comparison between many very similar (but also very different) types of triathlon watches. Because of this experience, they can also inform us (and you!) of any issues they’ve encountered with the watch, which further helps justify our selection and gives us the chance to give you the balanced guide you deserve. You’re welcome, by the way.
Brand - Yeah, we’ve put a pretty heavy focus on Garmin watches than we usually would, but that’s purely down to the sheer quality and variety (both in terms of features and price) that Garmin offer. However, we understand that everyone’s preferences are different, so we ensured we found a variety of other brands to make sure there’s something for everyone.
That being said, we haven’t just selected any old brands, and besides the plethora of Garmin products, we’ve also looked at reliable watches that offer the best quality on the market. These aren’t just brands we thought looked good or sounded cool, they are genuine and well-respected competitors of the most popular triathlon watch brands, and most times are often preferred to what many would consider ‘flagship’ products.
Features - There is such a massive amount of features possible on the modern triathlon watch, and because everyone’s training needs are different we’ve tried to find watches with the most useful features for beginners all the way to the experienced.
The most basic features you need to look for in a triathlon watch is a timer, and it also needs to be waterproof or water resistant and comfortable, but this is expected of any sports watch. It is also helpful to have an indicator for calories burned, and a step counter. If you want more advanced features, you’ll have the chance to pick from the likes of smartphone connectivity, GPS tracking, switching between sports in one session, and a heart rate monitor, and the majority of these watches will come with all of these included.
For triathlon training (and eventual participation) these are the most useful features, but many watches come with even more, which means you can use it for much more than just triathlons. You may end up paying more for these watches, but with the incredible amount of useful features it’ll end up being worth it.
Triathlon Watch FAQs
Q: Are all smartphones compatible with all triathlon watches?
A: Unfortunately not. While most triathlon watches will connect and sync seamlessly with your smartphone, there are some products which do not have the capability to do this. You can see this with the Timex (the last product on our list), which at less the $40 doesn’t come with the ability to connect to to Apple, Android, or Windows smartphones.
If smartphone integration is important to you for logging stats and data, and having as much control over your triathlon training as possible, then spending a little more on your triathlon watch may be worth it. This will make keeping records of training progress more straightforward and accurate and simpler than manual recording. This accuracy is crucial for any kind of training regime, and triathlon training is no different.
However, if you aren’t too concerned with keeping accurate logs (or just aren’t into all this shiny new technology) then a triathlon watch that offers lap memory, timers, and other basic features should suffice.
