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.

Muddy Dash is not your average mud run! Get ready for up to 3 Miles of messy mayhem. You and your friends/family can expect to run, walk, crawl, wade, slip, slide, and scream with excitement as Muddy Dash gets you fabulously filthy. We’re consistently striving for innovation and excitement in our obstacles, so there’s always a chance you’ll see something brand new! From the moment you step off of that start line, until you triumphantly cross the finish, we hope you’re prepared to have the time of your life among so many of your new best friends in the Muddy Dash community.
