Hamelin won a gold medal in the men's 1000m, and a bronze medal in the men's relay. The Sunday medals for Hamelin were his third and fourth on the weekend. On Saturday, Hamelin won the gold medal in the men's 500m race and finished with a silver medal in the men's 1500m.
In the men's 1000m on Sunday, Hamelin was in the lead the entire time according to the Canadian Press. He posted a time of 1:25.435 and beat Niels Kerstholt of the Netherlands by 0.348 seconds.
In the men's relay, Charles Hamelin was joined on the bronze medal podium with brother Francois Hamelin of Sainte-Julie, Quebec, Michael Gilday of Iqaluit, Nunavut, and Olivier Jean of Lachenaie, Quebec.
The fact that the Americans won the men's relay might come as a bit of a surprise to some. They are in a bit of a transition period with the retirement a year ago of Apolo Anton Ohno and the suspension of Simon Cho for tampering with Jean's skate at the 2011 World Team Short Track Speed Skating Championships in Warsaw, Poland.
Hamelin is in position to win multiple medals at a second consecutive Olympic Winter Games February in Sochi.
