Heffernan walking on air for the road to Rio
Victory went to Russia’s Sergey Kardyapkin in a new Olympic record, 3:35:59, with a string of personal best performances behind.
Robert Heffernan’s 3:37:16 was more than seven minutes inside his Irish record (3:45:30) and it would have been good enough to win every Olympic 50k up to Beijing four years ago where drug cheat Alex Schwazer set the Olympic record at 3:37:09.
