What Is a Backyard Ultra?

A Backyard Ultra is no ordinary race – it's a test of endurance created by Gary "Lazarus Lake" Cantrell. We’ve brought this challenge to Brighton, London and Manchester here in the UK!

How It Works

Run 4 miles (6.7km) on the hour, every hour. Each lap must be completed in under 60 minutes. Use any leftover time to rest and recover. Keep going until only one runner remains!

The Rules

Everyone starts together at 12PM. Complete your lap before the next hour to stay in the race. Faster laps mean more rest, but also more fatigue. There’s no minimum distance and no set finish line. You stop when you can’t start the next lap. It’s a personal challenge, whether that’s 1 lap or running through the night! Most runners go farther than they ever have before. Only one will finish. Will it be you?
