Distances and height gain

To ensure greater accuracy when giving distances, ascent and descent in the guide, detailed measurements were made using computerised mapping. Because of this, figures for distances, ascent and descent given in this edition may differ (in some cases significantly) from data given in earlier editions, which was produced by less accurate methods; any such discrepancy, however, is unlikely to cause distress to walkers accustomed to regular outings over mountain and moorland terrain. All figures have been rounded up or down since they are intended as a guide, and should only be used as such.

Walking times

How long it might take to walk 10 miles with a pack varies from individual to individual. Naismith’s Rule (1 hour per 3 miles, plus 1 hour for each 2000 feet of ascent) is purely a guide and needs adjustment to suit each walker’s personal abilities; not everyone can maintain Naismith’s targets over an extended day.

For this reason, the walking times given are already an adjustment of Naismith’s Rule based on my own experience; they are intended just to give an idea of how long you may need to be walking. Of course, the times given make no allowance for any kind of stopping – photographic, refreshment or otherwise.
