Hamelin captured a men's 500-metre event for his eighth medal in nine individual races this season and second gold.
Hamelin was second through most of the final behind China's Dajing Wu. But Hamelin managed to kick his foot out at the finish to post a winning time of 41.092 seconds. Wu settled for second in 41.095 with Russian Vladimir Grigorev third in 41.165.
“In the 500, I usually lead or I'm second, but in the first lap I will pass to make sure I'm leading for the reminder of the race," he said. "Today I was second right off the start and I tried to make a pass after two-and-a-half laps, but without success.
"I knew my last chance was going to be at the finish and I took that chance. We finished the race and I waited impatiently for the result. I got the gold medal.”
