In which sport does an athlete compete in a 'heptathlon'? The answer is athletics.

A heptathlon is a combined-events competition in track and field, the sport commonly called athletics. The name comes from Greek words meaning “seven” and “competition,” reflecting its seven-event structure. Competitors earn points for their performances, and the athlete with the highest total wins.

The women's outdoor heptathlon consists of the 100-metre hurdles, high jump, shot put, 200 metres, long jump, javelin and 800 metres. These events test speed, jumping ability, strength, coordination and endurance over two days. The women's Olympic heptathlon first appeared at Los Angeles 1984.

The men's heptathlon is a different, indoor contest. It is contested over the 60 metres, long jump, shot put, high jump, 60-metre hurdles, pole vault and 1,000 metres. This distinction explains why “heptathlon” is not simply one fixed list of events. It is also often confused with the decathlon, which has ten events and is traditionally the men's outdoor combined-events competition.
