City of Derry's Briege Connolly took the Edinburgh Half Marathon title at the weekend in a personal best time of 76 minutes seven seconds.
The 40- year-old Rio Olympian, who was 21 seconds clear of second placed Annabel Simpson, took 12 seconds off her previous best time, recorded in 2015 when winning the Larne Half Marathon.
Connolly, along with fellow Northern athletes Laura Graham and Gladys Ganiel, top the current Irish list and already have the necessary qualification times for the European Championships Marathon in August, where they will hope to set more personal best times.
Thomas Barr took his first step on the road to Berlin at the AAI Games yesterday in Dublin, the 25-year-old winning his first 400m hurdles of the year in 51.24.
While that was well down on the national record of 47.97, when he finished fourth in the Olympic final, Barr was pleased with the effort and now has 10 weeks before the European Championships kick off in the German capital.
Elsewhere, Sarah Healy underlined her star quality with an Irish U-18 1500m record of 4:13.32 in Oordegem, Belgium.
Portaferry athlete Ciara Mageean clinched a 1500m victory at Saturday's British Milers Club meeting in Watford.
The 26-year-old clocked 4:09.11 seconds to finish 0.99 seconds ahead of Scotland's European Junior 1500m champion from last year's Jemma Reekie.
English athlete Jessica Judd took third place in 4:12.58 as Mageean produced another encouraging run after her 13th place finish in the event at the Commonwealth Games.
