Collection: Electronics | race

Whether you're running to set personal records, complete a marathon or just enjoy nature, the right running electronics can make a significant difference. With modern technology, you can track your progress, optimize your training and understand your body's signals much better. At Transition Zone you will find carefully selected equipment that helps you get the most out of every run. We sell, among other things, advanced running watches from Garmin and Coros, lactate meters and precise heart rate belts - all equipment that is created for serious runners who want to train smarter, not just harder.

A running watch is much more than just a digital stopwatch. It is a personal trainer, an analysis tool and a loyal companion on all your runs. Garmin and Coros are among the most recognized manufacturers on the market, and both brands deliver top-class precision, functionality and ease of use. The watches can measure everything from distance, pace and elevation profile to recovery time, training load and sleep patterns.

Garmin is known for its versatile, feature-rich models – such as the Forerunner and Fenix series, which cater to runners, triathletes and multisport athletes alike. Coros, on the other hand, has gained popularity among ultrarunners and performance-oriented athletes, especially due to its long battery life, advanced running analytics and accurate GPS tracking. Regardless of the brand you choose, a quality watch will give you access to valuable insights that can help you structure and improve your training.

While many running watches have built-in heart rate monitoring, a heart rate monitor is still the most accurate choice if you want to work specifically with training zones. A heart rate monitor measures your heart rate directly at your chest, where the signal is strongest, and provides a more accurate and stable reading – especially during high-intensity or interval training. This means you can rely on the data to adjust your pace, manage your effort and avoid overtraining.

We sell several models of heart rate belts that are compatible with both Garmin and Coros watches as well as most training apps and devices. For serious runners, it is a must-have tool if the goal is to train effectively and with a greater understanding of the body's response. A heart rate belt is simple, but incredibly valuable in any runner's arsenal.

At Transition Zone, we've made it easy to find the best running electronics. We only select products that we would use ourselves and that we know will create real value for you as a runner. Whether you're training for a 5K, chasing a half marathon PR, or training structured towards your next triathlon, it's crucial that you have control over your data.

With the right electronic equipment, you not only get access to key figures, but also the opportunity to understand and react to them. You learn to control intensity, respect recovery and work with progression rather than just volume. Stop by Transition Zone and get guidance on choosing a running watch, heart rate belt or lactate monitor – or order online and get support included. Train with your head as well as your legs, and feel the difference when data and feeling go hand in hand.
