Huge difference between the longer Great River Rd and a diagonal route. You have many short climbs and easy grades on former vs. some climbs in the 500 ft area on the alternate. Try bikeroutetoaster.com for laying out your route. Shows an elevation profile, total climb and descent and estimated time, based on flat road speed and climbing gain per minute.
