The Limerick athlete equaled her personal best time of 7.91 seconds.
Another outstanding display from Sarah Lavin won her the 60m hurdles title at the 123.ie National Senior Indoor Championships in the Sport Ireland National Indoor Arena on Saturday.
The 29-year-old from the Emerald Athletics Club beat Molly Scott and Kate Doherty to the gold medal.
Lavin was just 0.7 seconds off the national record that Derval O’Rourke set in 2006 (7.84).
In an Olympic year, the Limerick native is in the form of her life as the Paris games gets closer.
She will take part in the 100m women’s event at the games taking place from the 26th July to the 11th August this year.
Before that though, there is a World Indoor Championships taking place from March 1st to 3rd in Glasgow, Scotland.
Speaking to Athletics Ireland, Lavin was upbeat after her win.
“I’d have loved to have seen a 7.90 or a 7.89 today but a 7.91 at home and to continue my consistent run heading into a World Championships is a good place to be.
“Derval (O’Rourke’s) national record is 7.84 from when she won the world title and it’s such a high bar, but obviously I want it and I know its going to take (a) perfect race to get there,” Lavin said.
