For any trek at this level, fitness is most important and you may have to improve yours before departure. Most C grade treks are equivalent to extended walking in mountainous terrain at home, but usually at significantly higher altitudes; climate and remoteness can also play a part. Walking days are usually between 6 to 8 hours although there may be some longer days for pass-crossing or similar. Previous trekking experience is desirable but not essential if you are confident of your physical condition.

At this level we recommend previous experience of trekking, preferably at altitude, and you need complete confidence in your physical condition and your ability to trek for many days without a break and be able to cope with difficult underfoot terrain such as scree, very high or difficult passes on steep mountainsides. Extremes of altitude and weather may also be encountered, and on some treks it may be necessary to use ice axe and crampons. Stamina is very important, as walking days can be from 6 to 9 hours or even longer on pass-crossing days
