There are several regional, national and international racing series conducted for the sport. The FIA World Endurance Championship is the most popular series that features races for both sports prototype and GT. The three most popular races in all of sports car racing are, the 24 Hours of Daytona, the 24 Hours of Le Mans, and the 12 Hours of Sebring. Automobile racing began soon after the invention of the gasoline- (petrol-) fueled internal-combustion engine in the 1880s. The first organized automobile competition, a reliability test in 1894 from Paris to Rouen, France, a distance of about 80 km (50 mi), was won with an average speed of 16.4 kph (10.2 mph).
