All the badest in judo will be there. 5 continents, 124 countries, 800 competitors. Watch live on ijf.org or the replays on Youtube. The preliminary rounds are usually on 4 different mats. The Medal/Final round is usually on 1/2 mats. I like to watch the semifinals of the preliminary rounds. These are the winners of four different brackets in each weight category. These are some of the best matches that determine who is guaranteed a medal(Gold/Silver) in the Finals and the loser has to fight the repechage winner for a Bronze medal.
