1. Set-up
1.1 The track shall be straight and 110m (T110), 90m (T90) or 60m (T60) long between the
start and ﬁnish lines.
1.1.1 There must be barriers on both sides of the track for its full length.
1.1.2 There must be adequate run-in / run-out space at either end of the track, as per
General & Competition rules #8.5 .
1.2 The start and ﬁnish lines are clearly marked. Where electronic timing is being used
the timing gates will be located here.
1.2.1 The ﬁrst and last 5 m of the track, ie. just within the start- and ﬁnish lines, is to
be clearly demarcated so that both right & le t-handers have a warning that they are
approaching the ﬁnish line.
1.3 The target tower, supporting three target faces, is located halfway between the start-
and ﬁnish lines
1.3.1 The distance from the edge of the track to the front of the centre target is 9m (a
distance of between 8.5 and 9m is acceptable).
1.3.2 The centre of the target faces is at a height of 180cm ±20cm above the ground-
level of the adjacent section of track. The targets should be aligned with each other on
the horizontal plane.
1.3.3 The middle target faces the midpoint of the track. The side targets are ﬁxed
with an interior angle of 114 +2 degrees to the middle target, so that they face a point
20-25m from the midpoint of the track.
1.3.4 Diagram of setup:
20 - 25 m
1.4 The target faces shall be round and composed of ﬁve concentric zones with diameters
of 90cm, 72cm, 54cm, 36cm and 18cm.
