Davicia Patterson produced the standout performance by an Irish athlete over the weekend, the 18-year-old smashing her own Irish U-20 400m record with a time of 52.57 in Geneva, Switzerland.
That moved her to fifth on the Irish all-time list and carved 0.31 off her previous best. It makes the Beechmount Harrier the fastest U-20 in Europe this year, which bodes well ahead of next month's European U-20 Championships in Boras, Sweden where Ireland is likely to have a handful of medal contenders.
At the same meeting in Geneva the quartet of Gina Akpe-Moses, Molly Scott, Sharlene Mawdsley and Ciara Neville broke the Irish women's U-23 record in the 4x100m relay, clocking 44.54 to finish third - a race won by the Netherlands in 43.25.
Another one in flying form was Sarah Lavin, the 2013 European U-20 silver medallist, who clocked a lifetime best of 13.26 to win the 100m hurdles.
At the British Milers Club meeting in Loughborough Nadia Power continued her fine form with a PB of 4:16.15 over 1500m.
Back at home Mick Clohisey and Sally Forristal claimed the national titles at the Irish Runner 5-mile in the Phoenix Park.
Clohisey claimed the men's title in 24:02, the Raheny man back in action seven weeks after competing at the London Marathon. Second was Colin Maher in 24:52 with Emmet Jennings third in 25:04.
Forristal was a clear winner of the women's race in 29:27, with Aine O'Reilly second in 30:21 and Catherine O'Connor third in 30:40. Raheny Shamrock won both team titles.
Luke McCann had another strong run over 1500m in Nijmegen, the Netherlands, the Dubliner clocking 3:42.37 to finish second over 1500m, just clear of Andrew Coscoran who bounced back to form to finish fourth in 3:43.27. Sean Tobin won the 5000m in a PB of 13:56.22.
