About London Backyard Ultra 2025

A Backyard Ultra isn’t your standard running event…

It’s a form of endurance event invented by Gary “Lazarus Lake” Cantrell in which you see how far you can push yourself.

… and we’ve brought it to London, England, United Kingdom!

The concept is simple.

Participants must run 4 miles (6.7KM), on the hour, every hour, until there is one runner standing.

Each lap starts on the hour and must be completed in less than 60 minutes.

When each lap is completed, the remaining time within the hour is typically used to recover for the next lap.

Participants complete hourly laps until there is only one runner still going.

It is this runner who is crowned the one and only London Backyard Ultra winner!

Will it be you? Get your tickets to find out!

Typically, participants who run a Backyard Ultra, smash their distance personal best.

All runners will set off and start together at 12PM.

They must have completed the four mile lap within 60 minutes to be ready to set off again at 1PM, and again at 2PM, and so on.

The quicker participants complete a lap, the longer they will have to rest but the faster they complete the lap, the more tired they’ll be.

There is no minimum distance or minimum number of laps you need to complete. Technically, everyone other than the winner is classed as a “Did Not Finish” (DNF). This is a race against yourself to see how many laps you can push yourself to achieve.
