The track time trial is a defunct track cycling event formerly held at the Summer Olympics. The event was first held for men at the first modern Olympics in 1896. It was not held again until 1928, when it became a consistent part of the programme and was held every year from then until 2004, after which the event was eliminated. A women's version was added in 2000, being held only twice before being eliminated along with the men's event after 2004. The distance of the time trial was one kilometre for men (except 1896, when it was one-third of a kilometre) and half a kilometre for women.
