I went out for a run today wearing my regular Polar RCX5 and a TomTom runner. Both are GPS equipped. At the end of the run I downloaded both and they had recorded the same operational time but the TomTom showed 0.4 miles shorter distance than the 14.2 recorded by the Polar. I plotted my route on Google maps and that distance agreed with the Polar.
Does anybody have any ideas as to what could have led to the discrepancy?
