How far did the Athenian youth travel to announce the victory at Marathon?

When a battle broke out on the plains near the town of Marathon between the Persians and the Greeks in 490 BC, it became clear that the Greeks had won. The strategist of Athens decided to notify the citizens of the victory over the Persians. He sent a young man from Marathon to Athens to convey the good news and to do it as soon as possible. As a result, the young man overcame 42 km and when he reached the city, he only managed to shout out “Rejoice, Athens, we won!”, And died.
