Polar RS800sd
For elite-level runners and coaches
Just like the RS800, the RS800sd has all the same advanced features to help you plan, monitor and analyze your training. However, what makes it different is the additional s3 Stride Sensor. This essential piece of kit provides you with information about how to improve your running technique. After all, in competitive situations, shorter or faster strides can have a dramatic impact on your performance.
- Measures heart rate combined with running speed, distance, cadence and average stride length
- Synchronizes with the Polar ProTrainer 5 software for guidance, analysis and creating individual training settings
- Highly sensitive barometric altitude sensor shows your elevation profiles
- Determines if your training program and recovery time are optimally developing your performance
- Objective measurement of your performance level during each run via the running index feature
