I don't I live one state over (Minnesota). I don't race just ride mtn bikes when I want to switch it up from gravel. I actually just have a fat bike with a 29er wheelset. You'll find that mtn biking is pretty big here in the upper midwest and come winter everyone will be xc sking or fat biking. So I'd take the assumption that competition is pretty tough but I honestly have no idea.

Also just for fun you should sign up for chequamegon 40, its a fun race, its actually more of a big party than a race. Not technical but fun.

Finally, once you get to Wisconsin, don't plan on shitting for a few weeks, you'll eat more cheese in the first week then you ever have in your life.
