A full day of walking over varied ground, which may incorporate a mixture of tracks and paths, rugged steep and rough pathless terrain, exposed ridges and non-technical scrambles requiring advanced skills, good fitness and stamina. Walks at this level are usually either long distance, which may or may not incorporate good paths, or in remote and mountainous areas. Typical walks include the harder or more remote Munros and Corbetts, routes such as Striding Edge in the Lake District, high level or remote long distance backpacks or ultra long distance events. Distances vary but are often over 15 miles with ascents often exceeding 1000m. An example is the Patterdale Round which takes in 17 Wainwrights, is 30 miles and has over 3000m of ascent. A full days walking may take anything from 8 to16 or more hours.
