The Git mirror is git-svn :) Cloning the mirror saves you the lengthy procedure of cloning the svn repo via git-svn (because the mirror already did this).

After cloning the Git mirror you can just do:
$ git update-ref refs/remotes/git-svn origin/master
$ git svn init https://geany.svn.sourceforge.net/svnroot/geany/trunk
$ git svn fetch


Best regards.
