For those opting for the 5K Honor Walk/Run, the course also starts and finishes at Swarthout Park, guiding participants on an out-and-back path towards the Upper Mississippi River National Wildlife and Fish Refuge Visitor Center, including a stretch along the South Loop Trail. Pacers will be available for the half marathon, and several aid stations will be positioned along the route, with the first offering water and porta-potties around mile 2.2.

Every finisher of the timed Half Marathon will be rewarded with a medal, awesome race swag, and the race's namesake treat: delicious mini donuts! 5K participants will also receive a medal and a high-quality technical event shirt upon crossing the finish line.
