Amateur athletes opened the 18th Abu Dhabi World Professional Jiu-Jitsu Championship at Mubadala Arena on November 9, beginning a 13-day program in Abu Dhabi that continues through November 21.
The organizer’s opening-day update puts expected participation at more than 10,000 athletes from 130 countries. That is the latest published projection, revising the earlier pre-event estimate of more than 12,000. Sheikh Khalifa bin Tahnoun bin Mohammed attended the opening and honoured amateur-category medalists.
