Ride as long a BRM ride as you can in 2018 in order to get early pre-registration (go to the calendar and change the 'Category' to 'RM only', there are still a bunch left in 2018.) Not having a BRM ride in 2018 may mean you miss out on a place.
Then in 2019 you ride the SR series (200, 300, 400, 600) within the windows specified (i.e. you must ride you 200 between 12th January and 28th April, so there's plenty of time).
Not too late.

The ride itself is 18th-22nd August.
