Can anyone clarify if the Mersey 24 hour counts as a pre-qualifying 600k ?
It is listed as my 600k for my Super Randonneurs series in 2018 but obviously it is not your typical 600k Audax ride.
Knowing the answer to his question will help with determining when I can enter PBP pre-registration (ie opening date for 400k or 600k as longest pre-qualifier).
