Two and a half hour mountain biking trip today in beautiful weather. Three big push-up hills, but lots of great interesting and fairly fast downhills, jumps, berms, all dirt tracks. We even found a very recently built track that is one of the best in the district.
I used the GPS in my phone as a trip log, but put it in my mad mate's backpack. We did almost 10 ks (I don't know the altitude variation) but the highest speed recorded was 124 kph!!!!! There is NO WAY that can be accurate, but even to get close to that he must have been zinging along. Because of the inaccuracy of the system, it sometimes registers a few kmh speed when stationary, but I've never seen error readings above 10kmh. How far off can a satellite GPS be, for speed?
