Borchin takes gold as Heffernan finishes 15th

There was no joy for Corkman Robert Heffernan in this afternoon's 20km walk at the IAAF World Athletics Championships in Berlin.

Heffernan finished 15th after a gruelling race through the streets of the German capital in 27-degree heat. His time of 1 hour, 22mins and 9secs was a season's best.
