In the Olympic marathon, there was an African athlete who dragged his injured leg through the entire race. Please introduce him in detail.

Ahwari was born in Mbulu, British Tanzania in 1938. He was the first Tanzanian athlete to participate in the Olympic Games. He participated in the men's marathon at the 1968 Mexico Olympics. Akhwari At 19 kilometers, he was squeezed down and trampled. He dragged his punctured knees and dislocated shoulders through the entire race. By the time he ran into the stadium, the awards had already ended, but people returned to the stands to cheer for the "uncrowned king."

The 1968 Olympic Games were held in Mexico City. The marathon on October 20th was affected by weather, and the results of the participants were mediocre. At 16:30, all other contestants completed the race. At 17:30, the awards ceremony ended. The audience began to get up and leave their seats. At 18:30, the organizing committee notified service stations along the route to begin evacuating, and spectators along the route began to go home in twos and threes. But not long after, a surprising news came: a runner was still running! Yes, that's Ahwari. In the dark night, he was still moving forward. Suddenly there was a reporter from Delta Sky Illustrated beside him. He asked puzzledly: "Why do you still run so hard when you know there is no chance of winning?" Ahwari was obviously unprepared for this question. After "running" silently for a while, he replied: "My motherland sent me here from 7,000 miles (about 11,265 kilometers) not to start the race, but to finish the race." At 19 o'clock, Surrounded by police cars, Ahwari finally entered the stadium where the lights were turned on specifically for him. He became a hero. He received far more cheers and applause than the championship. Because of the excitement, people forgot to count his exact time (at least 4 hours and 30 minutes), and the only ranking he got on the Olympic results book was: 57th among 75 people. The 18 players after him all dropped out due to various reasons. After crossing the finish line, he was taken directly to the hospital.
