World's Fair Ultras

The Inaugural Year 🔥

World’s Fair Ultras – April 18, 2026

Downtown Knoxville, Tennessee | Certified Loop Course | 3H • 6H • 12H • 24H

You’re built for more. You feel it when you run, when you dig deep, when you push past limits others never dare to test. But too often, races feel impersonal—like you’re just another bib number on a forgettable course.

You’ve trained, you’ve sacrificed, and you’re looking for something worthy of your effort. A course that honors what you’ve put in. A community that sees your drive. A race that feels like a celebration of the human spirit, not just a finish line.

World Fair Ultras is more than a race. It’s a celebration of human potential—a festival of grit, tenacity, and community, held on a fast, flat, and officially USATF-certified loop in the heart of downtown Knoxville.

Whether you’re chasing your first ultra finish or gunning for 100 miles, this is your moment.
