The podium performance is the third straight medal for Walker and sees her move into second place on the World Cup standings after four events.
Competing on the unique hand cut and historic ice track in St Moritz, Walker made a strong start recording the second fastest time in the opening run in 1:11.79 seconds. In the second and final run, Walker improved to finish with a time of 1:11.14 seconds which was again second fastest of the second round tying with Laura Nolte of Germany.
Her two-run combined time of 2:22.93 was just 0.15 seconds behind event winner Lisa Buckwitz of Germany, and another German Laura Nolte in second, just 0.02 seconds ahead of Walker in third.
“It’s so special, I’m really happy with my runs today and even happier that it resulted in a podium,” said the 31-year-old from Cairns.
“Each time I come here I learn more and more. I had to relearn the track with my new coach last year so coming back this year I didn’t have so much to learn, so I think that made all the difference.”
