She told the BBC: "I don't think it's going to sink in for a long time...[on the fourth and last run] I was totally relaxed and enjoyed it, it was a bit of a messy run, I'm so thrilled I'm here."
"As an athlete you give up so much but on a day like today, it's so worth it," she added.
Yarnold added that she wanted to "show the world" she was capable of winning the gold medal.
