I tentatively may be able to join this year, but don't base anything on my participation.
Benelux whilst widely covered, is rather easy for many on here to get to and could throw up the opportunity to do something a little quirky like a World Record attempt (or even an unofficial blitz with our own transport to see how many are possible in a set time frame), I also have
a few running routes around there I have been planning for a decade or so.
Perhaps factor in a bespoke Horta Townhouse visit, or we could all dream that someone could get a contact at the Stoclet Palace :)
I have a free period at the moment from about the 5th September - mid October, but again don't factor me in too heavily.
