A century is when 100 miles are covered in one ride. It is considered an ultimate test of power and is normally celebrated with commemorative events known as century rides. Centuries can be ridden solo, in teams, or in order to fund-raise for charity.
To ride a hundred miles, you must have good stamina, consistent speed, food, and water. The majority of riders train for weeks or months in order to make it. For long-distance cyclists and triathletes, it indicates how well they can ride for several hours and is included in Ironman training for many. Some cyclists ride further on double centuries (200 miles) or multi-day rides.
