Information on the route is given near the start of the route description. Distances are given in kilometres and miles, but for the most part these are irrelevant. What really counts is the nature of the terrain, the gradients on the ascents and descents, the conditions underfoot, and the amount of time it takes to cover each part. The total ascent and descent for each stage is presented in metres and feet. Route profiles show altitude on the vertical axis at 500m intervals and distance on the horizontal axis at 1km intervals. Conditions underfoot are noted in the actual route descriptions. The main features on the sketch maps are shown in bold type in the route descriptions, making it easier to monitor progress along the route.
Most trekkers measure their progress simply by time, and timings for various stages of the GR20 have been promoted so often that they might as well be carved in stone. In some instances, they are at least carved in wood on signs! As most trekkers are using the same times, they are given in more or less the same form in this book, in the route descriptions and in the summary tables in Appendices A and B. Use these timings as a basic guide.
