One of the most emotional wins was by Felix Sanchez, born in New York, but who races for the Dominican Republic.
He won gold in the 400-meter hurdles Monday at the London Olympics. He had previously won gold in the same race at the Athens Olympics in 2004. He did not win in the Beijing Olympics and his grandmother died while he was there.
Sanchez had an emotional win in London giving thanks to his grandmother. He carried a picture of himself with her.
He also had the words "abuela" or grandmother sewn into his running shoes.
"I just wanted to make her proud so I've got her name on my spikes," he told reporters, according to Reuters. "The day she died in Beijing it broke my heart. That's why I ran with the picture close to my heart."
Sanchez, 34, also became the oldest winner of an Olympic sprint event. He came back from injuries and some had expected him to retire.
His win shows the importance family support plays in motivating many of the athletes.
He was very emotional crying during the medal ceremony as he most certainly remembered his abuela.
