Consider starting on The Rock Island Line at Pleasant Hill Mo that trail connects to The Katy. My first Katy ride I did in 3 days starting in Clinton and that was too quick. The next year I started on The Rock Island Line and took 5 days that was more enjoyable I actually took more breaks to look at stuff. I rode Eastward to St. Charles. If I go again this year in June I will start in St. Charles and ride westward for a difference.
