Most people who enjoy a weekend in the hills or mountains at home are capable of undertaking a trek at this level: you need to be in good health and reasonably fit, and you will almost certainly be taking regular exercise. A trek could be graded B either as a fairly easy medium-duration walk, or as a harder, shorter walk. Some walking at higher altitude and the occasional longer or more difficult day may be involved, but generally conditions underfoot will be fair. A walking day would normally be between 5 to 7 hours long and no experience is necessary.
