Liquids, energy and breaks are required to maintain performance and concentration. Hot isotonic drinks are ideal for quenching your thirst and keeping you warm. Continually get your bearings (“I know where I am”) and be wary of following any existing tracks. Drink and eat (carbohydrates) about every hour in order to refuelyour body. Breaks shouldn’t last longer than 5 minutes to keep the body at “operating temperature”. Make sure you choose locations for your breaks that are protected from alpine dangers like avalanches, rock fall or buried flowing water. Preferably sheltered from the prevailing elements.
