While watching the Olympics the other night, I came across an unbelievable sight．It was not a gold medal, or a world record broken, but a show of courage．
The event was swimming and started with only three men on the blocks．For one reason or another, two of them false started, so they were disqualified．That left only one to complete．It would have been difficult enough, not having anyone to race against, even though the time on the clock is important．
I watched the man dive off the block and knew right away that something was wrong．I'm not an expert swimmer, but I can tell a good dive from a poor one, and this was not exactly medal quality．When he resurfaced, it was evident that the man was not out for gold — his arms were waving in an attempt at freestyle．The crowd started to laugh．Clearly this man was not a medal competitor．
I listened to the crowd begin to laugh at this poor man who was clearly having a hard time．Finally he made his turn to start back．It was pitiful．He made a few desperate strokes and you could tell he was worn out．
But in those few awful strokes, the crowd had changed．
No longer were they laughing, but beginning to cheer．Some even began to stand and shout “Come on, you can do it!” and he did．
A clear minute past the average swimmer, this young man finally finished his race．The crowd went wild．You would have thought that he had won the gold, and he should have．Even though he was recorded one of the slowest times in Olympic history, this man gave more heart than any of the other competitors．
Just a short year ago, he had never even swum, let alone race．His country had been invited to Sydney．
In a competition where athletes remove their silver medals feeling they have somehow been cheated out of gold, or when they act so proudly in front of their competitors, it is nice to watch an underdog．
