Professional Runner

In my quest to compete in Tokyo 2020, I needed to evaluate not only my training sessions but my recovery methods. My Polar allows me to better analyze my training results and reminds me during my recovery runs to ease up at times. I always knew the benefits of sleep to aid in recovery, but now I have comprehensive data and strive to improve my overall quality of sleep score. The morning Orthostatic Test results finishes the 24/7 ecosystem for training and the recovery process all athletes need. My favorite feature is the “tap” feature for recording splits, ideal for us track athletes!!
