I was thinking about buying a Garmin Forerunner (or a similar device) when I heard about the Nokia Sportstracker.
I've used the NST now for a couple of runs. It is a nice feature, but I am not sure, about the accuracy. Pace/Speed seems to be constantly too low/slow, it shows about 8km/h during the run, but if I calculate Pace/Speed based on distance and time I am 2-3km/h faster.
I ran a half-marathon last weekend with the NST, and it showed 22km in the end, which is about 5% off.
So is this Pace/Speed/Distance range of error comparable to a Garmin?
