Synchronized skating requires all-around skills, coach Saga Krantz said. “You have to be good at everything,” she said. “You have to be a good single skater, ice dancer, and a pair skater."

It's a sport "full of risks," Krantz said. “If one person falls, the chance that they take someone else with them is huge."

The Haydenettes are campaigning to make synchronized skating an Olympic sport. It is the only designated skating discipline not sanctioned by the Olympics.

There is no TV coverage of the synchronized skating world championships, and little media coverage. But awareness of the sport is growing slowly.

Skaters like Devin Wang have a lot of dedication, Krantz said. “It’s a serious sport,” she added. “They look cute and girly on the ice, they may giggle, but this, for them, is what they’ve been thinking of for years.’’
