Accurately rendered trail maps are not hard to produce, but they are rare. Below are three maps of the Nordic Gold trail at Giants ridge. They have been cropped to focus on the Gold trail. The first map contains terrain shading and an elevation profile as well as an accurate trail line. Below it is the Pepsi Challenge map from 2017. It uses a combination of trails for the race but does not have the trails positioned accurately. It is, however, far better than the map supplied by Giants Ridge (at the bottom). Notice the difference in the path around junctions 19 and 12 and the shape of the loop below junction 24.
Also, without the terrain and profile it is difficult to determine the trail’s difficulty.
