Colin Griffin has put the heartache of recent qualification bids to rest by achieving the Olympic standard for the 50k Walk at the IAAF World Cup of Race Walking in Saransk, Russia this morning.

Griffin was on two warnings after 10km but maintained his composure and form to move up the field to finish 15th in 3:52.55.

This was well inside the required 3:59 on what was his last opportunity to achieve the time.

Jamie Costin’s hopes of making his fourth Olympics were dashed when he was unable to finish in what were described as challenging hot conditions. It was the same for his team mate Michael Doyle.

Next in action are Olive Loughnane and Laura Reynolds in the Women’s 20k race

Robert Heffernan was in training for the 50k walk and took part in the 20k walk, producing another solid performance to place 12th in 1:21.51.

In the same race Brendan Boyce, who has dipped inside the Olympic qualification standard for the 50k walk on two occasions, finished 65th in 1:27.

Kate Veale finished an impressive sixth in the 10km Junior Walk. The World Youth champion, who will sit her Leaving Cert exams in a few weeks, crossed the line in 46:53 just off her personal best of 46:32.

In the same race Emma Prendeville finished 45th while Luke Hickey was 54th and James Treanor was 59th in the Junior Men's 10k race.
