Each year in April/May, the Monaleen GAA Tennis Club Mixed Doubles Competition is held for graded players and novices. The competition consists of a round robin element on one night with players qualifying for a QF/SF depending on the numbers participating. In general and again depending on the number of entrants, the competition is graded. Grade 1, Grade 2 and, Grade 3 men and women play together, Grades 4 and 5 men and women play together and Grade 6 and ungraded players play together. All matches are scheduled but players may agree to play a match in advance of the scheduled time. There is a finals day where all finals are scheduled. This is followed by a prize giving and social event in the Clubhouse.
