There's got to be three reasons why athletes decide to get involved in the heptathlon or decathlon events at an Olympic Games.
One: they love too many sports and can't actually decide which one to fully focus on so they just commit to all of them.
Two: they're actually the perfect all-round sports person and can adapt their skills to a whole range of different disciplines that is essentially the ultimate test for any athlete.

Three: they must be completely mad to take on and train for so many sports.
Either way, the heptathlon and decathlon events sees elite athletes battle it out over two days to be crowned the winner.
Men and women both have their own competition and gain points for how they finish in each event and whoever has the most points at the end of all the events will take gold.
