Making Transparent Maps for your Garmin GPS with GPX2IMG

I have had a number of questions from readers about how to get some certain trail data onto their GPS. That answer is complicated, because it depends on the trail data and it depends on the GPS you have. If the trail data you want to use is a simple track from someone’s previous ride, you can load it directly onto your GPS. Fitness GPS receivers (like the Edge models with mapping) can do a Virtual Partner based on that file and do performance comparisons and whatnot. With a mapping handheld, you get a basic navigation (it warns you if you deviate from the trail, but not much more). If that .gpx track has more track points than your GPS receiver’s track point limit, you have to reduce the number of points in the track by simplifying it (some programs allow you to do this) or by converting it to a route, which will prompt you to turn (best used on roads where turns occur at intersections, than on trails where turns often occur dependent on terrain).

SFA-Kit-SFA MTB Epic

Talking to some other riders in the area about our mtb trail opportunities, I got a somewhat crazy idea about linking our area trails together in a big, long ride. I wanted to do it all via county roads, but looking at maps of the area, it became apparent an all-county-road route would not be possible. The problem: the Angelina River bottoms. Between Nacogdoches and Lufkin, there’s only one road that crosses them: US-59. Not the ideal road because of its 70mph speed limit, but it’d really be the only option unless we REALLY wanted to go out of our way and probably spend days riding. Not this time.
