The club member, who claimed a silver medal at the World Triathlon Series Grand Final in London last year, will compete in the Olympic distance event on Thursday morning.
She said: "I am really happy with how things are progressing. I didn't have the greatest winter with a back injury but then got back to training and have improved as the season has gone on. My last two races have been my best this year so I feel in good form."
She added: "The Commonwealth Games is the biggest race of the year for me.
"This is a major championship and I want to put right my experience at the Olympics when things didn't go as I had hoped.
"It's also a chance to represent Northern Ireland for the first time on a world stage and with the event in Glasgow, it is almost like a home Games for us because there is going to be so much support.
"I know I have a lot of family and friends coming over so hopefully that backing can drive me on. The weather conditions should also be in my favour so I'm looking for a good race."
The women's triathlon event will begin at 11am with coverage on BBC television.
