In 2005 I joined some people from our local running club for Sunday morning marathon training runs for a couple of months. Though the mileage kept increasing, the basic route was always the same – starting & ending at what was then the running club’s office, then crossing the Centennial bridge & running on the bike path in Rock Island, then into town (sometimes through Black Hawk State Park), over the river via the arsenal bridge, and back to Davenport (and sometimes onto Credit Island). It was a lot of fun to have company one day a week, since I usually go alone.
