Prompted by something in the comments, cricket at the Olympics. Only done once, at the 1900 games.
only two countries competed, Great Britain and hosts France.
The French came second of course. But this:
The match….did not attract first-class status.
So, it was possible – in fact it happened to most of the team – that they were reigning Olympic champions, gold medal holders, for a however much of the century they lived and yet the’d still not played a fist class match. I rather like that….for the bloke who turned out in 1923 for Oxford V Cambridge has played first class cricket.
