Mageean beats Muir and sets new Irish 1500m record

Ciara Mageean has smashed Sonia O'Sullivan's long-standing Irish 1500m record with a stunning run that saw her beat rival Laura Muir for first place in the Diamond League in Brussels.

Mageean, who finished second to Muir in both the European Championships and Commonwealth Games, finally got the better of her Scottish opponent, claiming victory in a time of 3:56.63.

That time was not just the fastest that Mageean has ever run, beating her previous best of 4:00.15, but also broke O'Sullivan's previous Irish record of 3:58.85, which had stood since 1995.

Muir finished second in Brussels in 3:56.86, with Ethopia's Freweyni Hailu taking third, just .31 behind Mageean in a bunched finish.
