HELL & BACK ENDURE

The 12 Hour Challenge

A LAST ONE STANDING ULTRA EVENT -

WITH OBSTACLES!

THIS IS ABOUT SURVIVAL!

KILLRUDDERY ESTATE, BRAY, CO.WICKLOW

THE CONCEPT

Not distance.

Not pace.

Not speed.

Survival.

A 12-hour last person standing battle on a relentless 5KM obstacle course.

The Challenge

Outlast every other participant. Each lap tests stamina, grit and mental strength.

The Format

The conch shell starts the race. It sounds every hour, on the hour.
That’s your cue to go again.

The Rule

Not back before the next conch? You’re out. Simple. Brutal. Unforgiving.

Mental Battle BG.jpeg

Every lap becomes a mental battle.

Every decision matters.

Finish a lap early? Now you decide:

Stay at the start line and prepare?

or

Return to your personal aid station to recover, refuel and reset?

Every lap becomes a mental battle. Every decision matters.

You can tap out at any point - but only those still standing after 12 hours earn the right to say they made it thru’!

THE COURSE

A 5KM Hell & Back course repeated again and again and again.

No swimming required.​​​

Natural Terrain

Signature Obstacles

Deep Fatigue

It's not about a single fast lap -
but the ability to keep going when everything hurts.​​

Inspired by the legendary backyard ultra format -

but with the twist of Hell & Back obstacles!!

START/FINISH AREA & BASE SETUP

The heart of Hell & Back Endure.

​

The Start / Finish line sits at the centre of the site, with personal aid stations, camping and car parking all positioned around it.

 

You will pass through this arena every single lap.

You will hear the conch every hour.

And yes - you may question your life choices more than once.​​​​​

PERSONAL AID STATIONS

​

Every lap brings you back to your base.

Every hour the conch sends you out again.

Gold Circle

Closest possible position to the Start / Finish zone.

​

Maximum efficiency. Minimum wasted steps.

Standard

Located in the shaded blue/grey areas, a short distance further from the arena.

​

Each step counts.

Choose your set-up wisely -

your recovery plan is part of the race​​​​​.
