At the World Championships in Lake Placid last year, the 24-year-old completed a remarkable six-week introduction into the very top of the sport by claiming bronze.
Prior to that moment Yarnold had won two World Cup races from four and underlined herself as one of the best up-and-coming sliders on the globe by winning world junior gold.
This season has seen Yarnold compete at all eight of the World Cup rounds, finishing ninth last time out in Igls, with just one to go at the 2014 Olympic track in Sochi.
Yarnold will slide at the World Championships before then, the first two of four runs in St Moritz starting on Thursday, and stress-free she is willing herself onto the podium.
"I would be so pleased if I can medal again," she said. "I'm just heading there, hoping to perform the best I can. If that means I medal then great.
"I really enjoy the St Moritz track and when I'm having fun and enjoying my racing it always brings out my best performance.
"I'm just going to go into the World Championships and be under no stress. I don't want to put too many expectations on myself. I just really, really hope I have a great competition."
