The 1st North American ADCC Trials are underway. With nearly 800 competitors registered for the event, this is the largest event in the history of the ADCC trials. The two-day event has massive stakes: each of the five male winners will earn an invitation to the 2022 ADCC World Championships, while both female winners will get a free trip to the 2nd North American Trials.

Many of the brackets will take seven rounds or more to determine a winner, setting the stage for a lengthy test of attrition filled with mismatches and, potentially, surprising upsets. Each of the divisions are filled with rising stars and established veterans, but there’s no telling who will come out on top and punch their ticket to the World Championships next year in Las Vegas.
