How To Choose The Right Triathlon Watches?

Take a look at these pointers to choose the right triathlon watch that is best suited to your needs.

  1. Comfortable fit: Training for a triathlon is no child’s play. It takes hours of practice, and you need a watch that sits comfortably on your wrist. Find one that has flexible silicone straps and a smooth body. Avoid watches that are bulky and heavy, and instead, look out for watches that are lightweight yet firm.
  2. Durable: There are no brownie points for guessing this one. One of the most important things to keep in mind while choosing a triathlon watch is judging how durable and long-lasting it is. Ensure the triathlon watches have a rugged design, with strong tempered glass or a crystal lens. Some are even made with titanium to make them more long-lasting. Another key feature to look out for is that the watch is waterproof, so you can use it while swimming and track your moments there too.
  3. Battery life: As we have already established, your triathlon watch spends a lot on your wrist being active. Hence, you need one that will last you as long as your practice sessions do. A triathlon watch’s average battery life is anywhere between 6-8 hours, with features like GPS being turned on. Some even go up to 20-24 hours and longer. Make a choice depending on how long your triathlon race will last.
  4. Smooth transitioning: A good watch can easily transition between the various sports you choose to play. While switching between different sports, you might have little to no time to press buttons, and hence a triathlon watch needs to be able to transition without you pressing too many buttons. Most triathlon watches come with a single button that allows you to move from one sport to the other. Some even come with a triathlon mode that doesn’t require you to press a button to switch between sports.
