It was the summer Olympics of 1992. It was the quarter finals of the 400 metre sprint. British athlete Derek Redmond was one of the favourites for the gold medal. A lifetime of training had brought him to this moment. The starters gun fired and the athletes burst out of the blocks.

Halfway through the race Derek Redmond was leading. Then disaster struck. His hamstring went and he collapsed on the track. The agony on his tear streaked face was both physical and mental. It was a crushing blow.

Medical attendants ran to assist him. Derek waved them away. He came to race and he was going to finish. He got to his feet and started hobbling down the track.

The crowd was mesmerised. Officials didn’t know what to do. And then an older man ran onto the track. He brushed off officials who tried to stop him. He ran up beside Derek and placed his arms around him.

The man was Derek Redmond’s father, Jim.

“You don’t have to do this son” Jim said.

“Yes I do” Derek replied.

“Then we’ll finish this race together” came the response from Derek’s father.

Arm in arm, with agony on Derek’s face, tears on his father’s, Derek and Jim continued down the track. Derek buried his face in his father’s shoulder. His father’s strong shoulders carried his son physically and emotionally. Jim waved away officials who tried to stop them.

Finally, accompanied by a now roaring crowd, standing on their feet and applauding, Derek Redmond crossed the line. It became the defining moment of the Barcelona Olympics.
