Why is there not a category for Gourmet Race, both as a full race and for individual courses? Not only that, couldn't there be individual runs for each of the "8 Games"? I know the "Ultra" version does that, but I haven't got that game and don't plan on buying it anytime soon, and I doubt I'm alone in that.

There was at one point, but it was decided that it was unnecessary to have an official leaderboard due to extra work for mods as well as inaccuracy due to many people not submitting. If you go through runners' youtube/twitch vods, many of us keep track of our best times in individual games, but don't really compete outside of full game besides Arena
