Result: Ireland's Thomas Barr fourth in 400m hurdles final

Ireland's Thomas Barr finishes in fourth position in the men's 400m hurdles final at the Olympic Games.

Ireland's Thomas Barr has missed out on a medal in the men's 400m hurdles final by five hundredths of a second.

Barr was a surprise finalist after winning the third semi-final but he ran his own race as he looked to cause an upset in Rio de Janeiro.

He was sixth coming into the home straight, and despite a late surge to move himself into contention, he could not dip in front of Turkey's Yasmani Copello who hung on for third.

However, a small consolation for Barr is that he became the first Irishman to run under 48 seconds as he registered a time of 47.97s.

USA's Kerron Clement took gold in 47.73s, with Kenya's Boniface Mucheru Tumuti second in 47.78s.
