Every year, triathletes are looking for new technology to help them train and increase their speed and coordination. This can include LED lights, which are increasingly being used in training technology. So what are some new uses for LED lights in training?


Fitlight is a programmed system that monitors the user’s reaction time and analyses their behavior. Using eight LED lights connected to a tablet, the user must physically touch the lights to turn them off. The lights can be placed anywhere from the wall to the ground depending on how hard the user wants to train. Every touch is analysed by the system so that the user knows what to work on in his or her training schedule. Fitlight’s use of LED technology helps people with their reaction time, speed, coordination, and agility. This is great for those training for a triathlon in that quick reflexes are an important aspect of every race.

OnCourse Goggles

OnCourse goggles are great for training in open water that is not as clear as a swimming pool. These goggles have been made with small LED lights in each eyepiece that provides feedback to the user through flashes. These LED lights help the user stay on a straight path and lets them know if they have moved too far from their path. This new LED technology vastly improves swimming time so that the user can focus more on their speed instead of where they are going.

Cycling Safety

As one of the 3 elements of the triathlon, cycling perhaps poses the most danger. This is because it often requires extensive time out on the road in a non-race environment. It is vital, therefore, that the cyclist is visible at all times. Start-ups and entrepreneurs have developed a wide range of means for improving cyclist safety on the road. This ranges from illuminated cycle tracks to brighter lights, LED projections for drivers to see, and LEDs fitted to clothing to make them more visible.


Similar to OnCourse goggles, Lolite is designed to help with a swimmer’s speed and staying on the right track. This device hooks up to the user’s goggles and, using GPS, provides different color lights as feedback. Green lights mean that the user is on the right course and yellow lights mean that they are off track. If the user veers too far right, the yellow light will flash on the right side to alert the swimmer that they are off course.
