I'm not certain which listings you are looking at around Campbell Park area. From there you could access Elmore bike trails and go north through the University and catch the bike trail. It runs through town to the Tony Knowles bike trail. The trails go all the way through town with a few small diversions on the side streets. You would have sidewalks along the way though. I'm not certain on the distance but know that it is 32 miles round trip from Turpin to the Kincaid Chalet and back. Lots of hills but a great ride. Here's a great link for you.
