We will consider your endurance already when planning the activity, therefore it is quite unlikely, that you cannot keep up with the rhythm. Of course, there’s no guarantee for this. So if it happens, the best thing you can do is to alert us as soon as possible, so we can offer you an ideal solution. Depending on the type of adventure we have, we might have an extra rest day, or change the schedule of the next day, or if it is really necessary, we might cut the program and turn back. But remember, you have more strength and stamina than you ever imagined.
