How far did the soldier run from Persia to Athens?

The soldier, often referred to as Pheidippides, is said to have run approximately 26 miles (about 42 kilometers) from the battlefield of Marathon to Athens to deliver news of the Greek victory over the Persians. This legendary run is the inspiration for the modern marathon race. While the exact distance may vary based on the route taken, the traditional account emphasizes the significance of the journey rather than precise measurements.
