So really, what triathletes get with their specially adapted fitness wearables is three devices rolled into one.

Real time information at every stage of the triathlon

Fitness Tracker for SwimmingA triathlete has 4 personal bests to keep track of: their personal bests when running, swimming, and biking, and then their overall personal best in the entire triathlon as well.

An activity tracker for triathletes will be able to let the wearer know a variety of different types of information. Most important for a triathlete of course is heart rate, speed, and distance covered.

But, there are several types of information provided by such an activity tracker that are specifically suited to either running, swimming, or biking. When it comes to swimming, for instance, the activity tracker can measure stroke rate, as well as speed and distance covered.

Activity trackers for triathletes to suit at all levels

These small, comfortable, and of course waterproof and wetsuit friendly wearables are great for all kinds of triathletes.

Whether you are a professional athlete or training for a friendly charity event (or both!), you will be able to find the perfect activity tracker for you. Continue and check out our list of activity trackers for triathletes below:
