General
RULES
When the UIPM changed the rules and combined the running event with pistol shooting, Marosi had to be talked out of his rash decision to retire from the sport. He now feels the change is a good one. The sport added target shooting to the 'chase run' in the final event. He believes it makes the sport more exciting. "Some changes in the old rules were overdue." (Athlete, 25 Sep 2009)
ATTENTION
He admits having earned much more attention since his London triumph. "The huge media attention is flattering." But he laments that pentathlon doesn't get nearly sufficient recognition in Hungary despite the superb results over the years. (Athlete, 25 Sep 2009)
