First route
109 miles of road 24 miles of trail
Second route
90 miles of road 94 miles of trail.
The second route has extra 70 miles of trail and has 19 miles less road.
Not all roads are equal, of course.
Personally, I think I'd want to keep the Extra-trail to less-road ratio at about 2:1.
If they really like trails enough, then the extra distance is a bonus!
