The Inter Club league is for adult players (19 years old+). There are three Mens divisions:

There is a Mixed Doubles league. The format will be 3 doubles positions. They must be fielded in order of strength. All NTRP levels can be on a team, but it is set up so that #1 Doubles would be 8.5 (combined rating of the partners) and below, #2 Doubles 8.0 and below and #3 Doubles 7.0 or below. There is no restriction on the NTRP gap between partners (i.e., 5.0 can partner with 3.5) nor on age (players can be younger than 19).
