For over a mile, there’s no satellite reception. Sometimes, for reasons of its own, the GPS unit suddenly plots a point that’s waaaay off the trail. And often, the GPS track just jumps right across from Point A to Point C, bypassing a curve or corner. But, within these limitations, the track file will fit pretty well as you ride, and should keep you on the right path. How do I use somebody else’s Track File? If you don’t ride with a GPS unit, you can still benefit from track data. It allows creation of a very accurate map (but only as accurate as the data in the track file). Once a track file is created by the GPS unit, it can be uploaded to a computer. The line created by the track file can be shown on a satellite photo or a topographical map by many types of free software, for example Google Earth. This trail map can be used by ano
