London can spur Rob to medal in Moscow, says Loughnane

Race-walking legend Olive Loughnane believes Robert Heffernan can use his fourth place finish at the London Olympics as a springboard to success at the upcoming World Track and Field Championships in Moscow.

Heffernan will be targeting a podium place in the testing 50km event but faces a stern test from some of the home competitors in particular.

Loughnane, who retired after London, competed in six world championships with the crowning glory being her silver medal in the 20km race walk in Berlin in 2009.
