Phil Healy will be on a final mission when she heads for the European Indoor Championships in Poland in 12 days' time.
The 26-year-old Cork athlete is currently ranked sixth in Europe and with six making it in to the 400m final, she will be confident of improving on her achievement of reaching the semi-finals of two major indoor championships in the last three years.
On Sunday she warmed up for the Europeans with a terrific run at the Elite ILH Micro Meeting at Abbotstown.
Healy clocked a PB 51.99 in her first race of the season, with second-placed Sophie Becker (53.20) and third-placed Sharlene Mawdsley (53.56) also achieving the European Indoor mark set down by Athletics Ireland for the event.
"I'm absolutely thrilled," Healy told RTÉ's Sunday Sport.
"To get under the 52-second barrier is unbelievable. My [previous] PB was from 2018 so to break that is unbelievable. I know that there's more there but that may not come at a major championship because championships are all about championship racing.
"To come away with a PB, to get my position for seeding when it comes to the European Indoors and to come away with that sub-52 [was great], but mostly to get that PB under 52 seconds..."
The Europeans Indoors begin on Friday 5 March, and Healy will be desperate to make her mark. In Glasgow two years ago she suffered an unfortunate trip in her semi-final that scuppered her chances of progression.
In 2018 at the World Indoors she took third in her semi, with the top two progressing.
"Europe is red-hot at the moment but when you go to a major championships rankings go out the window in terms of the actual race because anyone can perform and anyone can mess up," Healy added.
"It's just about focusing on what you're doing and executing your own race when it comes to the major championships.
"The last two major championships I have got to the semi-finals in both the World Indoors and the European Indoors.
"The final is definitely the goal. We'll take it round by round. It's all about going out and executing my race and hopefully I'll get to that final."
