name a few historians who studied such a sports event?
The sophist Hippias, Phlegon of Tralles,  Julius Africanus
Olympiad
The sophist Hippias was the first writer to publish a list of victors of the Olympic Games, and by the time of Eratosthenes, it was generally agreed that the first Olympic games had happened during the summer of 776 BC. The combination of victor lists and calculations from 776 BC onwards enabled Greek historians to use the Olympiads as a way of reckoning time that did not depend on the time reckonings of one of the city-states. ("See Attic calendar".) The first to do so consistently was Timaeus of Tauromenium in the third century BC. Nevertheless, since for events of the early history of the games the reckoning was used in retrospect, some of the dates given by later historian for events before the 5th century BC are very unreliable. In the 2nd century AD, Phlegon of Tralles summarised the events of each Olympiad in a book called "Olympiads", and an extract from this has been preserved by the Byzantine writer Photius. Christian chroniclers continued to use this Greek system of dating a
