WHAT IS A BACKYARD ULTRA?

The format that changed everything.

A Backyard Ultra is the purest test in endurance sport. Every hour, on the hour, you run a “yard” — exactly 6.706 km (4.167 miles). Everyone starts together. The last runner still going wins. Not the fastest. The last one.

There’s no finish line. No cut-off. No podium for second place. You either complete the yard within the hour — and toe the line for the next — or your race is over. The winner is determined only when every other runner has stopped.

Every hour, on the hour

A new yard starts at the top of every hour. You control how long your rest window is — but the clock waits for no one.

6.706 km per yard

Exactly one quarter marathon, every loop. Each yard brings you back to camp — and to the next decision: in or out?

Last one standing wins

There's exactly one winner: the last person to complete a yard. Everyone else — no matter how far they ran — gets a DNF.

Community at the core

Between yards, runners share camp, food, and stories. This event is as much about people as it is about distance.

WORLD RECORDS

How far can a human go?

The Backyard Ultra was invented by Gary “Lazarus Lake” Cantrell in 2011 in Bell Buckle, Tennessee. Since then the format has spread to every continent — and the records have pushed the absolute limits of human endurance.

WHO IS THIS FOR?

Everyone. Genuinely.

That’s the thing about the Backyard format — it’s uniquely inclusive. A 100-mile veteran and a first-time trail runner can toe the same start line, and both will have a meaningful, memorable experience. You set your own goal. The event meets you where you are.

Rules and Information

The rules of a backyard ultra are applied consistently in all races around the world. These rules are very simple, and have been set to ensure that all runners that may qualify for championships have qualified in similar circumstances.

These rules are non-negotiable, and not even the Race Director can over-rule them.
