Black African participant of the Berlin Marathon at kilometer 40, Berlin, Germany, Europe. The Berlin Marathon (branded BMW Berlin Marathon for sponsorship reasons) is a major running and sporting event held annually in Berlin, Germany. The official marathon distance of 42.195 kilometers (26 miles 385 yards) is set up as a city-wide road race where professional athletes and amateur runners jointly participate. First initiated in 1974, the event traditionally takes place on the last weekend in September. The Berlin marathon is one of the largest and most popular road races in the world. In 2008 alone the race had 40,827 enrolled starters from 107 countries, 35,913 official finishers and more than one million spectators. Along with five other races, it forms the World Marathon Majors, a series offering a $1 million prize purse to be split equally between the top male and female marathoners. The most marathon world records for men and women have been set at the Berlin course, which is known for its flat profile, even surface, cheering spectators, and its frequently mild autumn temperatures. The event is split over 2 days. About 8,000 additional inline skaters compete at the marathon course the Saturday before the running event. Power walkers, handbikers, wheelchair riders, and a children's marathon (4.2195 km) are also part of the marathon weekend, which is organised by SCC EVENTS and currently sponsored by BMW.
