Kielder Chiller 24 Hour MTB Race route

The route will be a testing short circuit that incorporates long drags of forest tracks and plenty of single track going both up and down.  If it’s windy you’ll certainly have to wrap up warm and as darkness envelopes everything for more than half the ride you’ll be delighted to have an amazing vista spread out in front of you as the sun rises in the morning.  The suns rays warming your skin as they filter through the tree tops.

The route is a combination of forest tracks and solid singletrack.  For those who know the area there is a lot of the Deadwater red route in there which ensures rock garden climbs, switchbacks and fast, flowing descents.  The forest tracks are used for climbing but beware that the upper sections can be horribly exposed to the wind and the not often used eastern lower section can become a wee bit boggy.  There are plenty of overtaking opportunities.

The main marquee is used for the timing and you will dib here and find out split times etc.  There is no need to transition here if you don’t want to.  If you’re in a team and want to switch riders you can do it at your base somewhere out on the course.  Only one rider is allowed out on the course riding at any one time.

Kit List


Let’s be honest, there is every chance of inclement weather at Kielder in February. Kielder already sits well above sea level and temperatures are known to regularly dip well below zero in this part of the world. Be prepared! Here’s your list:

  • Enough fluid for 1 hour of riding
  • Emergency whistle
  • Waterproof/Windproof jacket/gillet (can be one jacket)
  • Emergency survival bag – you MUST take this out with you on the course
  • Spare food of your choice.
  • Mobile phone. It will only work when high up but it can be a vital lifeline in an emergency.
  • Helmet
  • Bike lights and means of powering them through the night.
  • Basic first aid kit.
  • FAQs

    Can I bring my dog?

    If you really want to then that’s fine but make sure it goes nowhere near the riders.  Tie it up behind or in your event vehicle.

    What about vehicles?

    One car per team is allowed out on the course.  You’ll get to park on a section of the forest track but make sure you are well across to the side – remember that you should try and leave enough space for an ambulance to get through.  Every vehicle other than the designated event vehicle will be placed in the alternative parking, details of which will be in the event info pack.  Due to the terrain of the route, only a small number of caravans/motorhomes will be allowed on the course route and these will be situated on the far side of the course.  Gazebos, small tents etc are fine.

    What’s happening about timing?

    Timing will be electronic so you can be sure it will be as accurate as possible.  We will try and update results online where possible – connections are not too hot in the wilds of Kielder!

    Any food on site?

    You must be providing your own food to get round the course.  However, the lovely cafe at Kielder Castle will be open from 8am until 8pm.  Mmmm.

    Where is transition?

    Transition can be anywhere on the course so you don’t have to trek down to the event hq if you’re quite some distance away.  All you need to do is pass on the timing device to the next rider if you’re in teams.

      The title says it all. Dont go unprepared you will regret it, a generator is a must be prepared for lots of hard technical climbs, some fantastic downhill runs and fast singletrack. The staff at the castle cafe were excellent and prepare some great food. The atmosphere is very laid back with everyone been very helpful and friendly and the on course eticate was always exemplary, I have to say I wont be putting myself through it again even though Im glad I did it
