DALBY's INFERNO and the 10 circles of suffering 

Now in its third year this superb event is going from strength to strength.

A back-yard style ultra marathon consisting of ten 5k laps starting and finishing at the same location.

"Fantastic event, really well organised. Enjoyed the challenging & varied route & the support from all the marshalls was much appreciated as was the superb soundtrack. Will definitely be back next year. Thanks to everyone involved in hosting"

"First 'ultra' distance event for me. Great event with brilliant organisation. Thanks to all involved. Didn't know what to expect or how it would go. Lots of great chat on loops 1-9. Highly recommend this event; I'll be back"

This event will sell out very quickly, so...

Are you prepared for the burn...? 

  • A 5km forest loop. 
  • Starting on the hour. 
  • Every hour. 
  • For ten hours. 

In the forest depths 

how long can you go 

before time catches you? 

Are you ready for the Roots of all evil? 

Can you handle No Worries hill? 

This is an event for all levels of fitness - one in which you can really challenge yourself to go further than you normally would, whether you'd be aiming for two laps or all ten.
Last year over 80% of runners completed all 10 laps.
And if you've ever wanted to own the kudos of an ultra marathon, then this is your chance to try in a supportive setting - managing all 10 laps is 50km; an ultra is anything over 42.195km...
The fee includes entry to the event, free entry into Dalby Forest (usually £10 per vehicle), plus two nights camping on the Fri and Sat night - and you're welcome to bring a friend or your family along too to support you (they can camp too). It's designed to be both social and challenging, and a great outdoor adventure weekend to look forward to!

Race format 

  • Based in Dalby Forest, this race follows a beautiful, not-exactly-flat (109m ascent) 5km trail loop through the forest. 
  • Once the start gun goes off, you have one hour to complete the lap. 
  • If you manage, you can start the next lap, which sets off exactly on the hour again.  
  • If you don’t manage, you sit out the next lap, but can still start again on any following ones after that, up to and including the ninth lap. 
  • If you manage all nine laps, you gain entry to the tenth and final lap.  The ultimate burn, in this final lap you'll be racing, legs on fire, for a finish in a blaze of glory... 

How many times can you endure the circle of suffering?

Included in the entry fee you get free entry to the forest, free camping at Adderstone on Friday and Saturday night (toilets/fresh water at site, no showers).

Camping is same location as start/finish.

We have an area at the Start/Finish for you to relax and refuel between laps. It is large enough to erect a small shelter and you can bring a friend to support you.

Start time - 9am, strictly.

Registration on Friday night from 6pm to 9pm or Saturday morning from 7am to 8.30am.
