I thought I read that somewhere. The date windows overlap so I suppose you could do a 300 on 16 March and then 200km on 28th April etc if you really wanted. Or just ride 4x600s so no one is in any doubt that you have qualified.
The Audax UK website says the time frames are:
The dates for these qualifying BRM events in the UK in 2019 (dates may vary from country to country) are:
200km: Saturday 12th January - Sunday 28th April 2019
300km: Saturday 16th March - Sunday 26th May 2019
400km: Saturday 13th April - Sunday 2nd June 2019
600km: Saturday 4th May - Sunday 23rd June 2019
I'm not sure those dates are all that relevant, because if they let you qualify with 4x600 or 3x400, 1x600 then you're not actually likely to have the longer events running in the earlier date windows.
