Here is a typical cx course I do in the Midwest USA.
About 10 weeks of the year I am all in on cross and trying to be competitive in cat 3.
The rest of the year I do plenty of gravel. By majority portion of the year I would use a pure gravel bike but the cx period wouldn’t be ideal. I’m still thinking crux since the geometry seems to blend both pretty well, not as long as a lot of other gravel bikes looks like.
