Two venues were used during the championships: the Irina Viner-Usmanova Gymnastics Palace and the Athletics and Football Sport Complex "CSKA".[1]
In a world championship, at least six athletes and four nations must enter each category. Because of insufficient registrations several competitions had to be merged. As B3 cannot be merged with any other category, they were instead held as Masters.[2]
