For an active endurance athlete. You want to improve your performance between training routines by planning, monitoring and analysing your training. Do all this and much more with RS400, the complete system for runners.
This also features the Polar S1 foot pod. Something that should be just as much a part of your training as your running shoes. Accurately measuring your running speed/pace and distance, this essential piece of kit will be with you every step of the way. And even though it attaches to your shoe laces, it's so light that you'll forget it's even there, which means it won't affect your running performance.
