Which leg are long jumpers with a prosthesis allowed to use at take off?

How it works: Competitors sprint along a runway and jump as far as possible into a sandpit from a wooden take-off board. The distance travelled, from the edge of the board to the closest indentation in the sand to it, is then measured.

A foul is committed – and the jump is not measured – if an athlete steps beyond the board.

Paralympic Games competitions involve six jumps per competitor, although a number of them, those with the shorter marks, are often eliminated after three jumps. If competitors are tied, the athlete with the next best distance is declared the winner.
