Because of the differences between events, it is rare for athletes at the highest level to compete in multiple disciplines, except for established 'doubles' such as the 100 m and 200 m, or the 800 m and 1500 m. Exceptions to this are the multi-event competitions of decathlon and heptathlon, which are designed to reward the best all-round athletes. Gold medallists in these events have a strong claim to be the best athletes in the world. | Because of the differences between events, it is rare for athletes at the highest level to compete in multiple disciplines, except for established 'doubles' such as the 100 m and 200 m, or the 800 m and 1500 m.
