The marathon distance of 26.2 miles originated from a legend in 490 BC where a Greek messenger named Pheidippides ran from Marathon to Athens, a distance of about 25 miles, to announce a military victory over Persia. In the first modern Olympics in 1896, the marathon distance was set at 24.85 miles to commemorate this legend. However, in the 1908 London Olympics, the finish line was extended to 26.2 miles so it would be in front of the royal family's viewing area. After debate, the 26.2 mile distance was officially adopted for marathons in 1924.
