Pretty basic GPS watch. I purchased it only because it was cheap .
Maybe I'll invest in one of those but not right now :P:. I've tested a few apps and they all have their own measurements (on the same track of course).... so I know now not to take that info too seriously. The thing with mapmyrun is that its measurements vary quite a lot sometimes.... up to 10%... So if we go with the most pessimistic numbers then some 130km out of the 1300 measured last year were imaginary.... quite a sad thought actually
