One of my bikes doesn't have the speed sensor, and I ride to work with it some times. The distance at the end is pretty much the same (to within 0.1 mile) as the one speed sensor. So I am assuming the GPS is measuring distance ok.
Also, I'd like to add to this. I used to run with this watch and the distance was pretty accurate. Not sure about the accuracy of speed but it seemed in line with what the other folks reported, with whom I used to run with.
