Derval O’Rourke won the gold medal in the women's 60m hurdles at the Woodie's DIY Senior Indoor Track and Field Championships at the Odyssey Arena in Belfast.
The Leevale AC athlete, who won world gold and bronze medals in the event in 2006 and 2010, put in solid performances in her heat (8.23) and also in the final where she clocked 8.21 seconds.
O’Rourke’s personal best remains the 7.84s she ran to win that world gold in Moscow in 2006 while she ran 7.96 to finish fourth in the European championships in Paris last year.
She said: "I am happy to have won, my times are not so great but technically I am getting better, I just need to be more aggressive over the hurdles."
Up and coming star Sarah Lavin (Emerald AC), who won a European Youth Olympic medal during the summer, finished second in 8.46, equalling the junior record set by O’Rourke in 1999.
In the men’s 60m hurdles, Ben Reynolds improved his under-23 record in the heat running 7.85.
The North Down AC athlete, who recently declared for Ireland, went on to run 7.75s to win the final, an agonising one hundredth outside qualification standard for the World Indoor Championships.
That performance earned him the Athlete of the Meet.
He said: "I was clean and faster over every flight which was good but I felt quite passive and need to square myself more over the hurdles. But it is good to know I am in that shape as I have missed some training in the last few weeks with a niggling injury."
Reynolds plans to race in Belgium next week to achieve the time needed.
In the women’s 60m, Amy Foster (City of Lisburn) took the title in 7.37, improving on her 7.39 from the heats yesterday. Joan Healy (Bandon A.C.) was second in 7.58 with Leah Moore third in (Clonliffe Harriers) in 7.70.
Seye Ogunlewe (Celbridge AC) got the better of Dean Adams (Ballymena and Antrim) to win the men's event in 6.79. David Hynes (Menapians) was third in 6.89.
The fancied Steven Colvert (Crusaders AC) who set a personal best of 6.86 in the heat was fourth in 6.91.
In the 200m, the men's title went to 17-year-old Marcus Lawler (St. Laurence O’Toole), who ran a personal best of 21.86, while in the women’s, Steffi Creaner won in a personal best of 24.31.
Eoin Mulhall (Crusaders AC) produced a personal best of 48.40 to take the men’s 400m title.
With Claire Bergin (DSD AC) only competing on day one of the championships, the women's 400m title went to Christine McMahon, who was back on the track after taking last season off, and had won her heat in a personal best of 56.06.
The men's 1500m saw a clean sweep for Ulster with Daniel Mooney (Letterkenny AC) winning in 3.52.83 from club-mate Ruairi Finnegan (3:54.84). Conor Bradley was third in 3.55.84.
The women's 1500m was a real battle between Orla Drumm (UCC AC) and Sarah Louise Treacy (Moynalvey AC), with both breaking clear of the field in the opening lap. Drumm finally kicked past Treacy with 100m to go to win by two seconds in 4.20.54.
In the women’s 800m, Ciara Everard (UCD AC) put in a convincing performance to win in 2.07.34 from Laura Crowe (Riocht AC) in 2.07.62 with outdoor 800m champion Siobhán Eviston (Raheny AC) third in 2:07.70.
The men's 800m title went to Brian Kelly of St. Abban's AC in a time of 1:54.94. The talented 17-year-old Karl Griffin (Tir Chonaill AC) took his first senior medal finishing second in 1:55.37. Dean Cronin (Blarney/Inniscara) was third in 1:55.41.
In other athletics news, national marathon champion Linda Byrne of DSD smashed her personal best time for 10km when she won the Creane and Creane Enniscorthy 10km on Sunday in 32 minutes 54 seconds.
That was well over a minute faster than Byrne's previous best of 34m20s set at the Flora Women's Mini Marathon two years ago.
Irish hopefuls were also in action around the world over the weekend.
In Australia, Joanne Cuddihy (Kilkenny City Harriers) got her season off to a good start by winning the 400m in the Perth Track Classic in 52.08, which should bode well for reaching the Olympic qualification standard of 51.55. That has been dropped from the 51.50 originally set by the IAAF council.
At the USA Track and Field Classic in Arkansas last night Ciaran O'Lionaird (Leevale AC) finished sixth in the mile in a personal best of 3.54.08, the eighth fastest time in the world this year.
