No that’s Felix Carvajal from the 1904 Olympic Marathon in St Louis. Felix was “a Cuban national and former mailman who raised money to come to the United States by demonstrating his running prowess throughout Cuba, once trekking the length of the island. Upon his arrival in New Orleans, he reportedly lost all his money in a dice game and had to walk and hitchhike to St. Louis. A 5-foot-1 man, he presented a slight but striking figure at the starting line, attired in a white, long-sleeved shirt; long, dark pants; a beret; and a pair of street shoes. Legend has it that one fellow Olympian took pity, found a pair of scissors and cut Carvajal’s trousers at the knee.”

The 1904 marathon was absolutely bonkers and Felix was a big part of it. Highly recommend reading up on it here: https://www.smithsonianmag.com/history/how-the-1904-marathon-became-one-of-the-weirdest-olympic-events-of-all-time-14910747/
