He trains for 3.5 hours. An hour, sometimes 90 minutes, of a session he runs as fast as he can for 1000 meters. The rest of the time he works on building up his strength. His trainer helps him. He does this about four days a week. Another two days a week, he trains on his own. Aaron is 10 years old. He is one of the best short-distance speed skaters in the United States for his age. It is a hard life for both Aaron and his parents. He has a few friends from school, where, by the way, he also excels academically. But mostly, his friends are other speed skaters and their siblings and parents. The sport attracts Asian Americans, particularly Korean Americans such as Aaron whose compact body type is perfect for this sport. In South Korea, speed skating is something of a national sport. Aaron's dream is to skate in the Olympics and to win a medal like the man who is training him with a careful eye, shouting words of encouragement and instruction as Aaron takes another corner at high speed, flying around the ice with other young people racing after him.
