Historically, I think that in the Olympic Games, in the track and field events in Athens, boys who run marathons are faster.
In the marathon campaign, the Athenians defeated the enemy with few and the strong with weak, and finally won the victory that inspired all Greeks, which is of great significance to the future battles.
In order to quickly tell the Athenians the good news of victory, Miltiades sent a soldier Felipedes to complete this task. When he ran from the marathon to the central square of Athens at the fastest speed, he said to the expected people, "Let's be happy, we won" and then fell to the ground and died. In order to commemorate the victory of marathon and commend Philippides' achievements, the first Olympic Games held in Athens in 1896 added marathon.
