We have a triathlon (3 events) and a decathlon (10 events).
We used to have a women's pentathlon (5) but I assume that was replaced by the heptathlon (7).
Has there ever been a sextathlon (6 events)?
Defending champion Natalia Dobrynska from Ukraine has just failed to register a score in the long jump - she's fouled three times,so her title defence is over.
