Skeleton world champion Lizzy Yarnold believes mental toughness was the key factor to her Sochi success.
Yarnold followed on from compatriot Amy Williams' Skeleton triumph in Vancouver four years earlier by adding the Olympic title to the World Cup crown she had secured earlier in the season.
Speaking to Sky Sports News upon her return to England, Yarnold, who was almost a second quicker than nearest rival Noelle Pikus-Pace in Russia, admitted she was surprised by the margin of victory, however insists she never doubted her ability to win gold.
Yarnold said: "I went to Sochi and it was just my dream for me to get there so just to be a part of the whole thing was really important to me and really special.
"I'd had quite a good season so far on the World Cup circuit, which is the normal circuit that we compete on every year - I'd podiumed on seven of the eight races and won the overall title so coming into Sochi I was already achieving more than I'd expected so new into the sport.
"Out in Sochi I just competed as best I could, put down four solid runs and I couldn't believe I won by almost a second!"
Yarnold, 25, produced a dissertation on mental toughness during her university degree in sports psychology and the Sevenoaks athlete cited that as a key factor in her win.
"My research on mental toughness was a real passion of mine. I loved studying it at university - I met loads of different athletes and interview them on what helps them be mentally strong in competition.
"One thing that stood out for me was having confidence in yourself and belief in your own ability. Especially in skeleton I'm down at a very different time to other competitors. I'm almost competing against myself and against the track so I was trying to focus on getting the best possible performance down that I could was all that I could control.
"I know that I'm mentally strong and physically strong and that I could go and win the race, and I did."
