Cycling is a sport, which requires the use of a bicycle. The Oliver brothers organized the first competition on May 31, 1968. In cycling sports in most cases, is a test for endurance rather than speed. The fastest speed according to the Encyclopedia Britannica was 204.73 kph in France on July 16, 1962 by Jose Meiffret. It might seem extremely fast, but that is nothing compared to the speeds achieved today with our advanced technology.
Other than the rider's training, genetic make up and competitiveness, the bicycle is the key aspect in speed and efficiency. This bicycle, called "the Ultimate", along with its rider Bruce Bursford, broke the world speed record of 334.6 km/h. This design was made aerodynamically efficient to cut down wind resistance. Just a gentle breeze? No, 90% of the resistance you feel is from the wind. This aerodynamic drag is made up of air pressure drag and direct friction, which pulls you backwards. Thus a drafting technique is used. The cyclist rides behind a larger vehicle or another cyclist that cuts through the air and 40% of the cyclist's energy is conserved. It is proven that cycling is the most efficient way of traveling because it takes only 100 calories for a cyclist to burn, for a result of 4828.03 m, while a car would die out after 85.34 m with the same amount of energy.
