Well, it depends on the walk, as walking the Yorkshire Three Peaks is going to require a much higher level of fitness than our 1-day Map Reading course. We have a wealth of experience dealing with all ages and abilities, and so our walks are always flexible and dynamic to match weather and ground conditions on the day, as well as the varying fitness levels and the overall needs of the group. As experienced Mountain Leaders, we manage the group in a professional yet subtle way. What we do say is that you need to have either a reasonable or good level of fitness (depending on the type of walk) as the natural environment can be demanding at times, and try to pick a walk that matches your level of fitness, ability and experience.
