Always ensure a margin for safety. If you are shivering, seek a warm place at once. Do not run long distances alone in adverse weather conditions. Observe running companions for signs of cold injury. Remove wet clothing as soon as possible.
Wet clothing increases the risk of cold injury.
Remember that replenishing fluids is just as important in the winter. Consider another form of exercise when adverse weather conditions make running dangerous. Leave word with someone or write down where you plan to run and when you will return. Carry some I. D. and change for a phone call. Take a whistle with you.
