Do the past editions have any practice sessions on gym or any other online judge if one just wanted to try it out?

        It's basically a bulgarian tournament that's used for determining our national teams. It's international and every country can join

    Thanks for the info! However, I'll only add international OIs to the blog, as there are way too many national olympiads to add them too.
