modern pentathlon at the 2012 Summer Olympics

The modern pentathlon at the 2012 Summer Olympics in London was held from 11 to 12 August 2012. The men's and women's events each involved 36 athletes. The venues for the events were the Copper Box (fencing), the Aquatics Centre (swimming), and Greenwich Park (horse riding and combined running and shooting).

Following the July 2011 modern pentathlon Olympic test event, UIPM president Klaus Schormann told Olympic news source Around the Rings that transportation was the key issue for the UIPM during the 2012 Olympics. "The transportation is important to get from the swimming and fencing to here in Greenwich Park," he said. "This should be properly organized, for the athletes but also for the spectators as well."
