Modern pentathlon competitions at the 2012 Summer Olympics in London are scheduled to be held on Saturday 11 August and Sunday 12 August 2012. The men's and women's events will each involve 36 athletes. Venues for the events will be the Copper Box, for fencing, the Aquatics Centre in Olympic Park for swimming and Greenwich Park, for the riding and combined running and shooting discipline.
Modern pentathlon contains five events; pistol shooting, épée fencing, 200 m freestyle swimming, show jumping, and a 3 km cross-country run. These will be the first Olympic Games in which the running and shooting events are combined; athletes face three rounds of shooting each followed by a 1 km run. Each of the three rounds of firing, athletes have to shoot five targets, loading the gun after each shot; they may then resume running. Misses are not penalised, but exceeding a maximum total time of 70 seconds will result in a penalty.
