I live in Michigan. Here's an idea that may help you.
Assuming your run is covered by a roof...
Get a staple gun and a roll of clear plastic sheeting. Staple the plastic sheeting around the run starting in late October or mid-November, depending on your first snowfall. It will keep the run dry and will keep the cold winter winds out.
In the spring, you can rip the plastic sheeting off your run and throw it out, or remove it more carefully and save it for the next winter.
You could also zip-tie those nice big blue tarps to your run.
