Heffernan fit and focused on his toughest test
Korzeniowski has retired since retaining his Olympic 50k title in Athens — a title which he won as part of a spectacular double four years earlier in Sydney.
Since before Athens, he has been coaching Irish racewalkers Jamie Costin and Robert Heffernan. Costin was driving his car in Greece when he was involved in that horrific accident on the eve of the Olympic Games.
