I've recently bought the new HRM-Pro Plus heart rate strap to use for football training and matches and have used it under several different activities but the distance and pace calculations are always miles under what they should be.
I have looked online and some people said to set it to an indoor run, which I did using indoor track, as well as trying cardio, and outdoor run. It has said that the distance has always been 100-250m, but realistically I am running at least 5 km.
Does anyone know how to improve the distance and pace calculation for the HRM-Pro Plus?
