Hypothermia is a condition in which your core body temperature drops below 35 degrees Celsius. If left untreated, hypothermia ultimately can result in heart failure and death.

Symptoms:

• Fatigue.
• Shivering.
• Muscle spasms.
• Clammy skin.
• Stammering.
• Hallucinations.

Prevention:

• Have warm clothes ready and be prepared for dramatic temperature drops during the event..
• Have additional, or a change into warm clothes for cold night-time walking.
• Carry or have your support crew carry a change of clothes in the event you get wet.
• At checkpoints when you rest, either cover up or change out of damp, sweaty clothes to avoid catching a chill.

If you become hypothermic, change out of wet clothes immediately; cover your head, face, neck and body with warm clothing; consume hot drinks and high-calorie food to maintain body temperature. Seek medical help at the nearest checkpoint.
