The 25-year-old was one of the few British swimmers to shine at the Games, where he won 200metres breaststroke silver, one of just three medals won by Team GB in the pool.
Like many athletes, he said 2013 was hard, but that Glasgow 2014, for whom the Scot is an ambassador, enabled him to fill the void.
â€˜Probably a month after the Olympics finished, Glasgow started coming into view for me,â€™ said Jamieson.
â€˜Going back to university and training after London was the hardest thing Iâ€™ve ever done after all the build-up and everything. Thereâ€™s a transition period and you feel deflated. Now, for me, the final in Glasgow will be the biggest race of my career, given the context.â€™
