However Shanahan’s decision paid off in the pool, and she was seen fighting back tears after securing silver on Friday night.
Having been inspired by seeing Hannah Miley in action at the 2014 Games, Shanahan told BBC Scotland News she hoped future generations might have be likewise inspired by watching her in the pool this time around.
“I’ve always said that if I can inspire the next generation of athletes coming through, then my job has been done,” she explained.
“I know after 2014 watching Hannah I felt inspired, and it would be nice to think that maybe there’s some younger girls watching the 200m backstroke this time, and maybe they’ll get into swimming from it.”
She joked that the main problem since last Friday was finding the time to get back to various friends and well-wishers sending her messages to congratulate her.
“I’m so grateful for the support, and with it being a home Games it feels like that support has been ramped up a bit, which is so nice to experience.”
