The Coros pod has been a game changer for my training. Prior to getting the pod, I felt like I was a pretty efficient runner. I learned quickly that I have some things to work on. The pod provides metrics that include stride length, stride height, ground contact time, left/right balance, efficiency, and power. In my opinion, the running power analysis is the most useful tool. I’ve used similar devices from other companies and none of them provided the in depth power data like the Coros pod. The pod was very easy to set up and always connects to my watch seamlessly. If you are looking for a simple, cost effective way to improve your running, I highly recommend the Coros pod.
