CVNRA Towpath Trail
Just south of Valley View's light industrial wilderness is a runner's bliss. Go to the trailhead off Rockside Road where it meets Canal Street, lace up your shoes, head south, and tell your knees to thank you later. The Towpath Trail is damn near perfect when it comes to running: There are plenty of bucolic distractions -- green fields, the Ohio and Erie Canal, wildlife; it's one of the best running surfaces in the area, made of packed, crushed limestone; and there's seldom much traffic. Even the mile markers are kind of snazzy.
