About Ultra Race USA

Ultra Race USA was created to make finding ultramarathons simple.

If you’ve ever tried searching for ultra distance races across different states, you know how scattered the information can be. Some races are listed on one site, others somewhere else, and many require digging to confirm dates details.

Ultra Race USA brings it all together.

Our Mission

Every Ultra. One Place.

Our goal is to provide a clean, organized, state-by-state directory of ultramarathons across the United States — including:

• 50K
• 50 Mile
• 100K
• 100 Mile
• Multi Day Events

We are actively updating and verifying races to keep the directory accurate and useful.

Why This Exists

This site was built by an ultrarunning enthusiast who believes endurance athletes deserve a better way to discover races.

Whether you’re chasing your first 50K or your next 100-miler, Ultra Race USA is here to help you find your next challenge.
