Alexander thinking sports is pointless (Plutarch, Lives 4.8)

But while he was still a boy his self-restraint showed itself in the fact that, although he was impetuous and violent in other matters, the pleasures of the body had little hold upon him, and he indulged in them with great moderation, while his ambition kept his spirit serious and lofty in advance of his years. For it was neither every kind of fame nor fame from every source that he courted, as Philip did, who plumed himself like a sophist on the power of his oratory, and took care to have the victories of his chariots at Olympia engraved upon his coins; nay, when those about him inquired whether he would be willing to contend in the foot-race at the Olympic games, since he was swift of foot, "Yes," said he, "if I could have kings as my contestants." And in general, too, Alexander appears to have been averse to the whole race of athletes; at any rate, though he instituted very many contests, not only for tragic poets and players on the flute and players on the lyre, but also for rhapsodists, as well as for hunting of every sort and for fighting with staves, he took no interest in offering prizes either for boxing or for the pancratium.

Also in the First Oration on the Fortune of Alexander, Plutarch's Moralia

"But of the genuine sayings of Alexander we might first review those of his youth. Since he was the swiftest of foot of all the young men of his age,​ his comrades urged him to enter the Olympic games. He asked if the competitors were kings, and when his friends replied that they were not, he said that the contest was unfair, for it was one in which a victory would be over commoners, but a defeat would be the defeat of a king."
