I love this idea, and would totally support it (if someone else organizes it!)

By the way, this was tried before, in 1936.

A global "People's Olympiad" was organized in Spain for July 19-26, which would have ended 8 days before the Berlin Olympics. But the Spanish Civil War started on July 17, with Hitler's backing and support.

Would it be worth all the effort to have an alternative Olympiad in 2022? My feeling is that it would be safer to shut the whole thing down (even if there weren't a pandemic to worry about, which I expect there will be in early 2022).
