What is the official marathon distance in kilometers and miles?

Marathon Distance Officially Set at 26.2 Miles (42.195 Kilometers)

The marathon, one of the most iconic long-distance running events in the world, has an officially recognized distance of 26.2 miles, which is equivalent to 42.195 kilometers. This standardized length has been universally adopted by international athletics organizations and is the benchmark for all competitive marathon races globally.

The origin of the marathon distance dates back to the legendary run of the Greek soldier Pheidippides, who is said to have run from the battlefield of Marathon to Athens to deliver news of victory. However, the exact distance of his run was not precisely documented. The modern marathon distance was standardized during the 1908 London Olympic Games. The race was extended to 26.2 miles (42.195 kilometers) to accommodate the British royal family's viewing preferences, starting at Windsor Castle and finishing in front of the royal box at the Olympic Stadium.

Since then, the 26.2-mile (42.195-kilometer) distance has become the official length for marathons worldwide, as recognized by the International Association of Athletics Federations (IAAF), now known as World Athletics. This standardization ensures consistency in race organization, athlete training, and record-keeping.

Marathon runners train extensively to cover this challenging distance, which tests endurance, speed, and mental fortitude. The event attracts millions of participants annually, from elite athletes competing for world records to recreational runners seeking personal achievement.

In addition to its physical demands, the marathon holds cultural and historical significance, symbolizing perseverance and human spirit. Major marathons such as those in Boston, New York, London, and Tokyo continue to draw global attention, celebrating the official distance of 26.2 miles (42.195 kilometers) and the enduring legacy of this extraordinary race.
