Course and facilities
The course starts on the Katy Trail and follows single-track trails beside the Missouri River. The 10k uses a loop with a turnaround cone on the Katy Trail, and the Half Marathon runs that loop twice with each lap split time recorded. Multiple aid stations are located along the course; the 10k and Half Marathon use additional stations.
The event provides chip timing, instant results, timed splits, custom bib numbers, a soft-spun T-shirt (guaranteed for registrations by June 15), a neck buff, free downloadable finish-line photos and video, and an awards ceremony on podiums. Packet pick up is available at Bike Stop Cafe the day before and in Racers Village on race morning. The event accepts donations to the St Charles School District Cross Country program, with proceeds used locally. Visit the organization's website for the most recent information.
