Two tape stripes (5cm wide and 10 cm long) will be placed on the ground, 100 cm away from the tatami centre; one stripe will be red and the other will be white; they will respectively mark the positions of each athlete both at the start and at the end of the contest. After initial salutation bow, athletes shall engage in the fundamental holds and the referee shall announce the start of the contest.


Distinctive marks on judogi

Athletes classified as  B1 (blind) must wear a red mark on the outer part of both sleeves; this must be  7 cm in diameter and must be placed circa 15 cm under the shoulder;
