Depends on the route I choose that day. I have routes that are all road, and some that are mixed road and MUP.
I tried the MUP last night, but there's too much snow (they don't plow it), so I jumped off at the next exit and took roads the rest of the way. Today in the single-digits and snow, it's the direct route, all road. My winter loop to work is 10 or 12 miles all road, depending on the variation.
In the three-seasons, my long loop is six miles road, nine miles MUP, two miles road. My hills, parks, and cemetery route can include at the end, either two miles of MUP and two miles of road, or a shortcut of one mile of road.
