The IBJJF has established their 2011 Event Schedule. While some dates are not secure, the months where they take place are pretty solid and mirror the past years. What is interesting are the number of "Internationals" that are established (now up to 10) . I would categorize these as smaller events, in comparison to the Pan and Worlds, that are in select cities around the world. It is probable that the Pan and Worlds will take place in California again in 2011. Take a look at the schedule here and start planning your competition schedule
