Why Marathon Is 42.195 Km

As a passionate runner, I’ve always been intrigued by the length of a marathon. Why is it 42.195 kilometers? It’s a peculiar distance that has become synonymous with this iconic race. In this article, I’ll delve into the history and logic behind the distance of a marathon, and explore the personal significance it holds for runners around the world.

The Origins of the Marathon Distance

The marathon distance can be traced back to the ancient Greek legend of Pheidippides, a messenger who ran from the city of Marathon to Athens to deliver the news of a military victory. According to the story, Pheidippides covered the distance of approximately 42 kilometers (or about 26 miles) without stopping, before delivering his message and promptly collapsing.

It wasn’t until the modern Olympic Games in 1908 that the official distance of a marathon was established as 42.195 kilometers (26.2 miles). The reason for this seemingly arbitrary extension of the distance can be credited to the British royal family.

The Royal Connection

During the 1908 London Olympics, the race organizers wanted the marathon to start at Windsor Castle and finish in front of the royal box at the Olympic Stadium. The distance between these two points happened to be 42.195 kilometers. To ensure that the race covered this exact distance, an additional 385 yards (or 0.195 kilometers) was added at the end.

By doing so, the marathon route would pass by the royal family and provide a memorable finish for the race. This decision forever altered the course of the marathon and established the distance as the standard for all future races.

Why 42.195 Kilometers?

Now, you may be wondering why the organizers didn’t just round the distance to an even 42 kilometers. Well, the answer lies in the precision demanded by the International Association of Athletics Federations (IAAF), the governing body for the sport of athletics.

The IAAF required that the distance of a certified marathon course be precisely measured and meet specific criteria. By adding the extra 0.195 kilometers, race organizers could ensure that the course conformed to these strict standards. This attention to detail and accuracy is a testament to the precision and dedication of the running community.

The Significance of 42.195 Kilometers

Over the years, the marathon has become much more than just a race. It has evolved into a symbol of endurance, determination, and the ultimate test of one’s physical and mental limits. The distance of 42.195 kilometers represents a monumental challenge that pushes runners to their absolute limits.

Completing a marathon is not just about the physical distance; it is a journey that requires months of training, discipline, and sacrifice. The distance itself serves as a powerful metaphor for life’s challenges and the importance of perseverance.


So, the next time you hear that a marathon is 42.195 kilometers, you can appreciate the rich history and symbolism behind this distance. From Pheidippides’ legendary run to the precision demanded by the IAAF, the marathon distance has a fascinating story to tell.

As a runner, I find great inspiration in knowing that every marathon I run is a tribute to the history and spirit of the sport. Whether you’re a seasoned marathoner or someone contemplating their first race, the distance of 42.195 kilometers represents a true test of character and an opportunity for personal growth.
