The pentathlon is still held indoors, where the heptathlon cannot be held as arenas are too small for the javelin throw. It was added to the IAAF World Indoor Championships as an unofficial event in 1993 and officially in 1995. The indoor pentathlon is held over a one-day period. Each athlete completes one event at the same time, then there is a 30-minute break until the next event. The current world record is 5013 points by Nataliya Dobrynska at the 2012 World Indoor Championships.
