Summarize this content to 2000 words in 6 paragraphs PARIS — American men have competed in track and field at the Olympic Games for 128 years. Never before, however, has there been someone as young as Quincy Wilson.The 16-year-old will run a leg on the U.S. 4×400-meter relay team Friday inside Stade de France, his coach Joe Lee told NBC News. With that run, Wilson will become the youngest male U.S. track Olympian, eclipsing middle-distance runner Jim Ryun, who was 17 at the 1964 Olympics.There is no guarantee Wilson will run in Saturday’s Olympic final; it is common for countries to alter their lineups between preliminaries and finals. Even at an Olympics where the youngest competitor is an 11-year-old Chinese skateboarder, and a 14-year-old Australian skateboarder has earned a gold medal, Wilson’s presence was remarkable given the strength and endurance required by his chosen event. The 5-foot-9 Wilson, however, had proven himself in recent months by not only dominating in the 400 against his high school peers while at the Bullis School in Potomac, Maryland, but producing one of the most stunning performances at the U.S. Track and Field Trials in Eugene, Oregon, in June, running a sub-45-second 400 in three consecutive rounds and finishing sixth in the final. At a meet in Florida on July 18, Wilson backed up Team USA’s decision by lowering the Under-18 world record to 44.20 and outkicking a field of professionals. The time ranks as the world’s 11th-fastest time of the season, fourth-fastest by an American, and would have been good enough for sixth in Wednesday’s Olympic 400-meter final.The showing led USA Track & Field to include him in the pool of runners eligible to run on a U.S. relay in Paris. Making the relay pool only certifies an athlete is an option for U.S. coaches to consider, however. When Wilson wasn’t chosen to run on the mixed 4×400-meter team that eventually won silver, the teenager’s opportunities to don the U.S. jersey dwindled.Wilson’s sister, Kadence, is a sprinter and long jumper for James Madison University while a cousin, Shaniya Hall, runs for the University of Oregon, and there were early signs Wilson would join them as a sprinting star. After an 8-year-old Wilson finished fourth in the 400 at the AAU Junior Olympic Games, he returned the next year and won the first of his five national championships. But no stage, of course, was as big as Friday on Stade de France’s purple track.
