Sports May is a programme of sporting activities aimed at lesbian, gay, bisexual and trans people.
It will give individuals a chance to get involved in new sports, or to improve their abilities. The range of events includes swimming, football, athletics, tennis, rugby, cricket and volleyball.
The month will then be followed up by a number of tournaments in June.
Under the Rainbow has been speaking to one of the volunteers helping organise the event, Phil Facey.
