How do I find out which courses are running local to me?

As all courses are administered and delivered locally, you will need to contact your local County Cricket Board for guidance regarding upcoming courses, as they will be able to confirm specific information such as dates, venues and availability: https://www.ecb.co.uk/county-cricket-boards 

You are not restricted to the County you reside in; if you are willing to travel to another County, you can also contact those County Boards for further information.
