After seeing this year's BCM has been and gone, I notice that I did a virtual 'Welsh SR' - as it was over a 12 month period as the 400 was this year.
600K - BCM - May 2017
300K - Peregrine Mountain Roads - July 2017 [1]
200K - Pistyll Packing Momma - Sep 2017 [2]
400K - Brevet Cymru - May 2018
However I'm hopefully going to do it officially this Audax season.
[1] A event resurrected only just for last year see

[2] By my calculations this is over 80% is in Wales and certainly all the hills are. I've not noticed this mentioned up thread and should be added to the list.
