Since the start of the I'm A Speedrunner series of tournaments, many new people have joined in and at the same time many have also disappeared by taking part in the past and not taking part in recent tournaments.
There have so far been 14 main tournaments (one of which was cancelled), which have seen people from all over the world participating, with most of the competitors hailing from countries such as Australia, the United Kingdom and the United States.
