The Millstadt Parks Biathlon & 5K returns on September 13, 2026, offering runners an exhilarating blend of running and cycling through the rolling farmlands just outside Millstadt, Illinois. The race kicks off at dawn with a comfortable average temperature around 17 degrees Celsius that gradually warms to 27 degrees by midday under clear skies. Participants start their journey in front of the park office on Main Street north of downtown. As they set out, runners will enjoy soft rolling hills and expansive fields, navigating hard yet dry surfaces for a smooth running experience. The picturesque five-mile course showcases the natural beauty of the area before transitioning smoothly into the bike leg covering 22 miles. Highlights include high-speed turns and undulating terrain that add to the overall challenge. This biathlon has been an annual event since its inception in 1985, raising funds each year for community programs through the Millstadt Park Fund. Race day conditions promise a comfortable environment with minimal rainfall but hard and dry trail surfaces. A light breeze averaging eight kilometers per hour adds an extra layer of challenge without becoming too strenuous. Participants should report to the park at least one hour before their 8:00 AM start time, ensuring they are well-prepared. Registration opens online on June 1st through https://raceroster.com/events/2026/138338/millstadt-parks-biathlon-and-5k with a deadline of September 7th. The registration fee is $28.74 for individuals and teams, covering both the run and bike portions. Bibs can be picked up from August 30th to September 12th between 9 AM and 5 PM at Millstadt Town Hall or on race day starting at 6:30 AM with your ID and payment if collecting bibs on race morning. The event fosters a sense of camaraderie among runners and cyclists, making it an unmissable community gathering. Proceeds from the race support local parks and facilities benefiting children and adults alike. With its challenging course and rewarding finish line festivities, this biathlon promises to be a highlight for residents and visitors in St. Louis seeking unique outdoor experiences.
