You can easily do that if you ride across the McKinley Bridge or the Clark Bridge in Alton and connect to Madison County's trail network. I think they have over 100 miles of trails alone, and there are loops (I also hate backtracking!). I like riding the St. Louis Riverfront trail to get to McKinley, but some of that may be underwater with the flooding.
