In 1992, Derek Redmond was running the race of his life -- the 400-meter dash at the Summer Olympics. In the previous Olympics, he was forced to withdraw 10 minutes before the race due to an Achilles injury but now he was he was ready and heavily favored to medal. His father was in the stands cheering. The race began and 175 meters into it, he pulled his hamstring muscle and collapsed on the ground. As the stretchers rolled out, he refused to get on. And he started hobbling towards the finish line. The rest of the story is best seen in this uplifting video.
