In competition, 20% of the lanes will be designated as compulsory standing or kneeling, and there must be as even a split as possible between the two. Most competitions have 40 targets arranged in 20 lanes, so it is usual to have 2 standing lanes and 2 kneeling lanes. Grand Prix events have 25 lanes, so there will be 2 lanes of one position and 3 of the other. Standing or kneeling targets must be no more than 45 yards (41 m) from the firing line.
