Thomas Barr beat world champion Jehue Gordon in the 400m hurdles in a new stadium record of 48.94 at a pulsating Morton Games in Dublin last night while the mile record for Morton was also shattered by American Will Leer in 3:51.82 as 10 men went under four minutes.

Home favourite Rob Heffernan finished fourth in the 3km walk at the Cork City Sports meet tonight, but was pleased to set a new personal best over the distance as he continues his preparations for the European Championships.

Another masters world record for Robert Heffernan in the men’s 3,000m race walk and a sub 50 second 400m hurdles for Thomas Barr as an engaging 63rd Cork City Sports last night in Bishopstown gave a significant marker for what lies at ahead at the European Championships in Zurich in August.

Rob Heffernan will be making a short stopover in Cork on Tuesday evening as he attempts to defend his Cork City Sports 3,000m race-walk title.

Olympic champion Usain Bolt was unable to claim victory in his first Diamond League race of the season as Justin Gatlin continued his impressive form by edging out the Jamaican to win the 100 metres in Rome.
