"Immediately after the Beijing Olympics, I wanted to at least do one more season because I didn't want to leave the sport on that note because they (the Beijing Games) hadn't gone so well," Deas told BBC Radio Wiltshire.
"So I definitely knew that I had at least one more season in me from that point onwards.
"But in my head, it was quite an open-ended situation. I didn't really have a hard end point in mind, and I think partly that was because I didn't really want to approach any race knowing for sure that it was going to be the last time I ever stepped on ice.
"Because the thing about our sport, really, is that there's no way to just do it recreationally."
She finished second in her final race, a World Cup event at Sigulda, Latvia, and has fond memories of that day.
"I managed to win a medal, which was a lovely sign off," said Deas.
"So I was thinking, 'well, if this is the last time I set foot on ice, what a nice way to do it'.
"I mean, that's the thing, isn't it? For a lot of athletes, it's other things that contribute to that decision to move on and do other things. Sometimes it's injury, sometimes it's just performance.
"It was a really nice race as well, because a lot of my family were able to be there as well, and friends, and it was a lovely atmosphere.
"And it was the end of a season that had actually been very healing for everyone after the Olympic disappointment, to be able to go back onto the World Cup tour and have some success and kind of really show everyone what we could do again."
