Following the announcement from NI executive on Thursday 19th November it is now likely that all tennis courts will have to close for two weeks from 27th November. The guidance excerpt is as follows:
Sport

Indoor and outdoor sport is not permitted, other than at elite level.

Elite sporting events must be held behind closed doors without spectators.

All sports facilities such as leisure centres and gyms, swimming pools, tennis courts, golf courses, fitness and dance studios must close.

Individual/ household outdoor exercise and school PE can continue. Physical activities, such as walking, running, cycling, horse riding, or just walking the dog, bring many health benefits.
