At the end of that road where it meets Shirley Road. Coming from Croydon you'll see a golf club on your right near the end (just before the RAB), just after that is the entrance to Trinity School, we'll meet there.
Alternatively for you Sean you could drop down to Elmers End, turn right by the Tesco and keep going all the way to Ashburton Park in Addiscombe, then turn left up Shirley Road and go up there to Trinity RAB - saves you doing pointless miles in to Croydon.
