50 metres, or 50-meter dash, is a sprint event in track and field. It is a relatively uncommon non-championship event for indoor track and field, normally dominated by the best outdoor 100 metres runners. At outdoor athletics competitions it is used in the Special Olympics and a rare distance, at least for senior athletes. It is an alternative to the 60 metres running event. The imperial distance for 50 metres is 54.68 yards.
The Helsinki Grand Prix was an annual one-day outdoor track and field meeting held at the Helsinki Olympic Stadium in Helsinki, Finland. Established in 1959, it was originally organised by a local athletics club, Helsingin Kisa-Veikot (HKV). It continued in this format, with Apu magazine a key sponsor, for nearly three decades. In 1987, HKV came to an agreement where the Finnish Amateur Athletic Association took on the operating costs of the competition. The Finnish Association ceased this arrangement in 1992, causing the cancellation of the 1993 meeting due to financial difficulties.
