The Scot has never seemed out of her depth in the field during a dominant eight-year spell but there is fierce competition for the title in Glasgow this year in the form of world No.1 Aimee Wilmott of England.
There are other Scots intent on making a bit of a splash in the lead up to the Commonwealth Games, with Michael Jamieson to race tonight against Englishman Andy Willis in the 200m breaststroke final. The pair are both training partners and rivals for gold in the pool this summer.
Jamieson was in good form last week during the Scottish Championships - during which he won in the 200m event - while there is anticipation that there will be further success today from Robbie Renwick and Caitlin McClatchey. Renwick is targeting his fifth straight 400m freestyle title.
The British Championships could glitter for Scotland then, while there are other swimmers eager to use the event in Glasgow to prepare themselves to make waves when they return to the city in the summer. Welsh backstroke specialist Georgia Davies, for one, intends to use today's contest to assess her new training regime ahead of the Commonwealth Games.
"For me there's not so much pressure this week because of the pre-selection of the Welsh team," said Davies, who won bronze in the 50m backstroke in Delhi four years ago. "I've gone to a new programme and it's really different from the training I've been used to doing so it's going to be a good opportunity for me to practise.
"If it doesn't go to plan then me and my coach can sit down and think about what we need to do to get it right for Glasgow."
The British Championships are being held in the renovated Tollcross International Swimming Centre, which will host the swimming in Glasgow this summer. "I'm quite excited to see what the pool will be like and to test it out before the Games," added Davies.
"It's the first chance that I'll get to swim there when it's being altered and readied for the Commonwealths so it's exciting."
