I have the Garmin Running Dynamic Pod and the stride length isn't working. Sometimes it doesn't show anything, most of the time my stride length is half of normal. I'm normal at 1m, but it shows only 0,5 meter. When this happens, vertical ratio isn't working as well, or the data isn't correct.
I first thought my RD pod was broken, so I bought a new one, but I have the same problems with the newer pod.
Hope you can help figuring out what causes the problem.
