Team Scotland's Michael Jamieson believes that tonight's 200m breaststroke final is "biggest race" of his career so far.
The Scot qualified for the final with a time of 2:08.78, setting a new Games record in the process.
"London is done and dusted and I have got great memories of that. This year I had the world record time on my alarm clock every morning - that is my target and I hope to get there this week," Jamieson told BBC Sport.
"I'm trying to stay as relaxed as possible and remember that I am here because I love my sport, but the nerves are starting to build. This is the biggest race of my life.
"And this is at home, where things started. With all the support we have had I feel this is not just a goal for me but everybody who has lent their support in my development."
The 200m breaststroke final is due to take place at 9.01pm tonight
