Canada won the women's speed skating team pursuit in dramatic fashion, as a Japanese skater slipped and crashed on the final corner with her team leading.
Japan were ahead by 0.32 seconds going into the final half-lap and seemingly on course to be crowned Olympic champions, but Nana Takagi got one of her blades caught in the ice, causing her to fall and slide into the barriers.
With the clock only stopping when the third of the three skaters crosses the line, that meant Canada snatched the gold medal at the very last moment and broke the Olympic record in the process.
"It feels really surreal right now. There is such high emotion. Going into the race we wanted to make ourselves proud," Valerie Maltais said. "We didn't want to put pressure on ourselves, it is a privilege to be in this final. Coming across the line, I just couldn't believe it."
Isabelle Weidemann added: "We are still thinking, is this real? We knew we had a strong team, we knew we could put pressure on Japan and all the other strong teams today. I don't know if we'd thought about this possible outcome."
As the shocked Canadian skaters celebrated their victory, the three Japanese skaters — Takagi in particular — were inconsolable on the other side of the track.
In the B Final, the Netherlands — who would have been expecting to reach the A Final and compete for gold — beat the Russian Olympic Committee to win bronze.
