To reduce the risk of fatigue on a long trip, dress to protect yourself from tiring elements, such as wind, cold, and rain. Limit yourself to no more than six hours of riding per day and take rest brakes at least every two hours.

• Try to minimize the number of rest breaks.
• Use artificial stimulants, like caffeine, if you feel drowsy.
• Dress warmly to avoid getting too cold during the ride.
• Schedule more than 12 hours of riding a day.
