Hmmmmm maybe Let's Run has unknowingly stumbled on the way to MWCGA (Make World Cross Great Again)!
They will have more runners than most European nations (2).
So, why not let "club" teams run?
Kind of like the Nike does it- they can be any group as long as they're from the same country. So, if Nike (or anyone else like some billionaire who loves cross) wants to send a team they can. They can send one team, they can send 12 teams.
They would be sure to advertise to help out their investment.
Who cares if one country or another wins, I want the company that makes the shoes I wear to win.
