Or move it to Sweden. They’ve dealt with it as I would, If I was in the ‘captains seat’.That meaning wasn't clear from your previous post - there's no reason why the sportives couldn't proceed without oversea entrants- if covid restrictions were lifted in the uk by that time. I'm sure numbers could easily be made up from the UK.
Whether sponsors would foot the bill for a smaller event (without the UCI races) is another matter.
Anyway, my preference would be an event open to all nationalities. The global community is going to be dominated by blame and finger pointing for years due to Covid19. International sports will help break down those barriers.
