Ciara Mageean was almost lost for words after smashing Sonia O'Sullivan's 27-year-old 1500m National record at the Diamond League meeting in Brussels last night.
Mageean put in the performance of her life to take home victory against a world-class field. The Portaferry flier had been in excellent form coming into the event, winning silver medal at both the Commonwealth Games and European Championships in recent weeks.
On each occasion, Mageean finished runner-up to legendary track star Laura Muir. But last night, the roles were reversed as Mageean forced Muir back into second place, while at the same time making Irish history.
