Marathon History

The marathon boasts a rich and fascinating history that spans over 2,500 years, making it one of the world’s most iconic endurance events. The origins of the marathon can be traced back to ancient Greece, where the legendary run from the town of Marathon to Athens was undertaken to deliver the news of a Greek victory over the Persians. This historic feat laid the foundation for what would become a celebrated athletic tradition.

Fast forward to 1896, the modern Olympic marathon was introduced, capturing the imagination of athletes and spectators alike. Since then, the marathon has grown in popularity, becoming a symbol of perseverance and human spirit. The standard marathon distance of 42.195 km (26.2 miles) was established in 1921, and it has remained the benchmark for marathon courses around the globe.

Today, marathons are held in cities worldwide, from the bustling streets of New York City to the historic routes of the Boston Marathon, the world’s oldest annual marathon. Each event brings together runners from all walks of life, united by their passion for the sport and their determination to conquer the marathon challenge.
