Do we really need walking poles and head torches?

Do I need walking poles
Using current statistics, we calculate that walking poles will remove 437.5 tonnes of pressure off your knees over a Three Peaks Challenge. One team must carry at least two pairs of walking poles. With the assistance of walking poles an injured person can also be assisted off the mountain preventing a full-scale rescue.
Head torches are invaluable for night time ascents or descents, or when visibility is poor, since they allow you to keep both hands free. Every team member must have a head torch and spare set of batteries.
