Curve strating line in track and field?

Answer 1

not quite sure what you're asking here... if you're asking if they curve the starting line, then the answer is that it depends on the race most individual distance (600m+ in most cases) events start on what's called a 'waterfall line'. This line is a progressively curved line intended to compensate for the added distance of running in the outside lanes. As soon as the gun goes off, the runners fight for position in the innermost lane. For almost every sprinting event (less the 55, 55h, 100, 110hh) and some relays, runners begin in a 'staggered' position, in which each lane has its own starting line, again to compensate for added distance in the outer lanes. These lines are not curved, though the 'break line', a line that may or may not be used (depending on the race and meet) to signify when a runner can 'break' out of his or her assigned lane and move to lane 1 without penalty, is sometimes used in a race and is curved in the opposite direction (away from runners in outer lanes).
