To further motivate your workout and keep your performance under control, wear one of the heart-rate monitors designed by TomTom on your wrist. The heart-rate monitor checks your heart-rate and other parameters to measure your endurance and performance. In addition, you can choose from 50 training modes or even customise one according to your targets. Do you love training to the sound of music? The integrated player has enough space for 500 tracks: create your own playlist for your sports sessions! During your run the integrated GPS detects rhythm, speed, position and distance.
