WHY IS THE MARATHON 42.195 KM?
During the first Olympic games the marathon was roughly 40km, about the distance from Marathon to Athens. The official distance of 42.195km comes from the 1908 London Olympics. Organizers in London wanted the course to go from Windsor Castle to White City stadium (about 26 miles), and then added an extra 385 yards inside the stadium, to have the finish line be in front of the royal family’s viewing box. Hence the tradition of yelling “God save the Queen” in the last mile of the race!
