Heffernan celebrates World walking gold

Ireland's Rob Heffernan celebrates his victory in the 50km walk at the World Athletics Championships in Moscow.

The Cork man's gold medal was Ireland's first for 18 years, the first by an Irish male for 30 years and only the country's third ever at the championships.

"World champion, to say it out loud, doesn't seem real right now," said Heffernan, as he attempted to assess the scale of his achievement.
