Challenging - This may entail some walking away from well-maintained footpaths over rough ground, rocky sections and bog. Ascent/descent may be over 1000m/3000ft per day and distances covered may be over 10 miles (16km).
Moderate - Walks each day are normally between 6-8 hours, with several days involving some mountain ascent in the order of 2000-3000ft and distances covered of between 4-9 miles (10-14km).
Easy - Walks each day are between 5-7 hours, with mostly lower level walks with little ascent on well maintained trails. Distances will be mostly circa 6miles (10km) but can be up to 10 miles/16km in good conditions.
