What is the other name for this athletics track event in which Papa M'Baye N'Diaye competed at the 1964 Summer Olympics and the 1968 Summer Olympics?
4 × 400 metres relay The 4 × 400 metres relay or long relay is an athletics track event in which teams consist of four runners who each complete 400 metres or one lap. It is traditionally the final event of a track meet. At top class events, the first 500 metres is run in lanes. Start lines are thus staggered over a greater distance than in an individual 400 metres race; the runners then typically move to the inside of the track.
