About this race
City of the Sun 5K Trail Run 2026
Mark your calendars and plan to join us on Sunday, November 8, 2026, for our number 1 fundraiser of the year! The Annual City of the Sun 5K Trail Run takes participants to sections of the Site that many wouldn’t see otherwise. This 3.1-mile race ebbs and flows through paved, wooded, grassy, and, at times, muddy terrain. You won’t find another race around with a backdrop like ours! Make a difference at Cahokia Mounds by participating in our Trail Run.
