Heptathlon

A heptathlon is a track and field combined events contest made up of seven events. The name derives from the Greek ἑπτά (hepta, meaning "seven") and ἄθλος (áthlos, or ἄθλον, áthlon, meaning "competition"). A competitor in a heptathlon is referred to as a heptathlete.

There are two heptathlons – the men's and the women's heptathlon – composed of different events. The men's heptathlon is older and is currently held indoors, contested at the IAAF World Indoor Championships in Athletics. The women's heptathlon is held outdoors and was introduced in the 1980s, first appearing in the Olympics in 1984. It is currently contested in the athletics programme of the Olympics and at the World Athletics Championships.

Women's heptathlon is the combined event for women contested in the athletics programme of the Olympics and at the World Athletics Championships. The World Athletics Combined Events Tour determines a yearly women's heptathlon champion. The women's outdoor heptathlon consists of the following events, with the first four contested on the first day, and the remaining three on day two:

The heptathlon has been contested by female athletes since the early 1980s, when it replaced the pentathlon as the primary women's combined event contest (the javelin throw and 800 m were added). It was first contested at the Olympic level in the 1984 Summer Olympics. In recent years some women's decathlon competitions have been conducted, consisting of the same events as the men's competition in a slightly different order, and World Athletics has begun keeping records for it, but the heptathlon remains the championship-level combined event for women. Nafissatou Thiam, representing Belgium, is the 2024 Olympic Gold Medallist, after successfully defending her previous 2016 and 2020 titles. She is also the reigning European Champion. Anna Hall, representing USA, is the current World Champion. Katarina Johnson-Thompson, representing Great Britain, is the current Commonwealth Champion. Odile Ahouanwanou. Yekaterina Voronina, Kiara Reddingius, Luisarys Toledo and Ariana Ince hold the African, Asian, Oceanian, South American and NACAC (North American, Central American and Caribbean) titles respectively. Adriana Rodríguez, Marthe Koala, Swapna Barman and Elenani Tinai hold the Panamerican Games, African Games, Asian Games and Pacific Games titles respectively.

There is also a Tetradecathlon, which is a double heptathlon, consisting of 14 events, seven events per day.

The heptathlon scoring system was devised by Dr Karl Ulbrich, a Viennese mathematician. The formulae are constructed so that, for each event, a designated benchmark performance (for example, approximately 1.82 m for the high jump) scores 1000 points. Each event also has a minimum recordable performance level (e.g. 0.75 m for the high jump), corresponding to zero points. The formulae are devised so that successive constant increments in performance correspond to gradually increasing increments in points awarded.

The events are split into three groups, and the scores are calculated according to the three formulae:

P is points, T is time in seconds, M is height or distance in centimeters and D is distance in meters. INT is the integer function, also known as the floor function, signifying that the result is rounded down to the nearest lower (or equal) whole number. a, b and c have different values for each of the events, as follows:
