The marathon distance today is 42195 meters. Incidentally, the marathon distance was first determined as a function of the distance between Marathon and Athens at the first modern Olympics held in Athens. It used to be thought that this distance was 40.42 kilometers, when in fact it was only 36.7 kilometers. Of course, none of the numbers match the 42,195 kilometers mentioned at the beginning, because this distance, which is still used today, was already established at the 1908 London Olympics. The 40.42 kilometers had to be extended by another 2 kilometers because the runners who ran the marathon had to run from Windsor Castle to the White-City Stadium and simply would not have reached the finish line. From then on, it became the official Marathon distance. Why 195 was the end of the distance and why couldn’t the total distance be around 42,000 km? Because Queen Alexandra insisted that the finish line be in front of the royal lodge, and that would have missed that 195 meters. ?
