We will be using the bibtag system. Timing strips will be located on the back of your race bib. Wear the bib number visibly on the chest. Do not fold or crumple your bib number or tag. Use a pin for each corner of the bib number, do not pierce the timing strip. Do not remove the foam spacer. The foam increases the detection rate of your tag. The tags do not have to be collected after the race, you can keep the bib with the tag as a souvenir.

The half marathon course begins at 7:00 AM sharp in downtown St. Charles, and from there runners head west through residential neighborhoods before turning right toward Foundry Street and cutting through nearby Timbers Park. The race route gains more trees at this point, providing runners with a scenic route of the St. Charles countryside.

At around mile 4.5, the course continues north onto the Mid County Trail, veering left and northward onto the countryside of Crane Road just before mile 6. Runners return to the Mid County Trail just past mile 8, this time heading south. After mile 10, much of the path on Dean Street leading to the finish line is familiar from the first half of the course.
