EVENT INFORMATION

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, Manchester, Wirral and London here in the UK!

How it works:

  • Run 4.167 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!

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?

Course Design

Join us in Brighton, Manchester, Wirral, and London for a safe, clearly marked run. All routes are marked with fluorescent “Caution Runners” signs to alert other park users and directional arrows to keep you on track.

  • Brighton & Manchester: An out-and-back course – run to the top of the park/trail, then follow the same route back.

  • Wirral: A looped course with changing direction – head 1 mile away from the start, reverse course and run 2 miles back past the start/finish line, then turn once more for the final mile to complete the loop.

  • London: A looped course – run two laps of the forest circuit, powering through each turn to complete your distance.

Event Directions & Facilities

Compulsory kit

The only equipment we require you to bring on the day is a head torch, chest torch, or waist torch.

We also strongly recommend wearing some form of high-visibility clothing during the night loops to help keep you and other participants safe.

General:

  • Run 4.167 miles (6.706 km) every hour.

  • A new loop starts on the hour, every hour.

  • You must be inside the starting corral when the bell rings to begin the next loop.

  • Each loop must be completed within one hour to count.

  • Any time left in the hour is your recovery time.

  • No late starts or early starts are permitted.

Backyard Ultra Rules

Loops:

  • Except for toilet breaks, competitors are not permitted to deviate from the course at any time until their current loop is complete.

  • No non-competitors (including eliminated runners) are allowed to accompany active runners on the course.

  • No personal aid is permitted while completing a loop.

  • Artificial aids, including trekking poles, are not permitted.

  • Slower runners must allow faster runners to pass.

  • If you fail to complete a loop within the hour, you are DNF.

Timescale:

  • The race continues until only one runner remains.

  • The last remaining runner must complete one final loop alone to be declared the winner.

  • There is no set finish distance or time. The winner is determined by endurance, not speed.
