The Kielder Ultra Trail is set in the vast expanse of Kielder Water & Forest Park. The Park spans 600 square kilometres & is home to the largest forest in England & the largest man-made lake in northern Europe. The area features mile upon mile of purpose-built trails including forest walks, woodland singletrack and heather clad moorland.

Competitor Feedback:

"What an amazing event and definitely worth flying over from Australia. A big thankyou to the organisers Who I met and the rest of the team including the wonderful volunteers who welcomed us with big smiles and words of encouragement. Will definitely be recommending this event to friends in OZ ??"Mark Backhouse

" A massive thank you to each organiser, marshall, photographer and runner. You all helped this girl complete her first ultra. So much support, so friendly, fantastic location. You all helped create an amazing experience. Thank you and well done " Jen Runner Bean

"Superb event again! Marshals and organisers the loveliest in the business! Even stopped and showed me an Osprey at the start of the 100km! Really love this event, definitely coming back! Thank you!" Jodie Smith

"What a friendly supportive atmosphere. I have never been to an event before where every single runner supports each other, even the guys and girls who won the 100k took the time to encourage and support me on my way around. They are amazing. The marshals, event staff and photographer were all amazing too, friendly and encouraging, and helped me complete my first ultra (as a non-trail runner). Thank you all" Lynsey Mackintosh

"Once again High Terrain put on a superb event in stunning scenery. The 100k felt like 2 different laps after the rain set in. A huge thank you to the staff/marshalls for your support and look forward to seeing you all at Ennerdale later this year" Dean Sartin

"Fantastic race, loved every minute. Tough first ultra but the view were worth it"  Jenny Yeo

Entry Requirements (All Distances): We've experienced some fantastic conditions at Kielder at the previous events, ranging from a covering of snow to warm sunshine (both in one day!). The course ascends to 320m on open moorland & the weather can change quickly. To ensure you're prepared for the conditions that can be encountered at this time of year, all participants must dress appropriately for the conditions with suitable clothing & footwear. Click HERE for mandatory kit.

Terrain: There are no real technical aspects to the course, this will be a truly fantastic ultra offering great variety in terms of scenery & terrain. The courses are approx. 99% off road (the longest road section is across Kielder Dam). Featuring a fantastic combination of woodland singletrack, forest trails, open moorland, sections of the Lakeside Way multi-user trail & the blue graded mtb route. There are also sections on forestry roads (some of which have a loose stone surface).

They are undulating/hilly circuits encompassing Kielder Water. The climbs & descents are generally long & gradual & not steep or technical. Suitable trail shoes are strongly recommended/essential.


Route Highlights: This is a superb route whether you are looking to complete your first ultra or an experienced runner. Starting and finishing at Kielder Castle, the 50k loop encircles the whole of Kielder Water. The route features sections along the tranquil Lewisburn Valley, Kielder Viaduct, Bakethin Reservoir nature reserve, Bellingburn Valley & sections of the Lakeside Way multi-user trail & the blue graded bike trail The route also climbs onto open moorland to offer stunning panoramic views over the whole of Kielder Water and across to the Scottish Border.

Courses: The routes will be fully marked so no need for navigation. All courses are accurately measured & are the exact distance.

GPS Measurement: We try to ensure that we measure the courses as accurately as possible using a number of different recording devices & various recording settings. Please note that the actual distance and elevation gain can vary between +/- 5 % depending on the measurement method, i.e. make & model of watch/GPS unit, unit settings, tree cover, etc.

 82k Time limit:  14hrs. There will also be intermediate cut off times  at various locations.

 50k Course Overview:   Starting from Kielder Castle the initial section follows Viaduct Wood alongside the North Tyne river, before climbing steadily up to Castle Hill. Passing Devil's Lapful, an open section offers some fine views across the valley. This is followed by some awesome twisting singletrack on the blue graded mtb trail.


Soon after, the remote Wainhope Bothy (once an old farmstead) is reached. A longer section on forestry roads follows, before the steady climb up to Black Belling fell (323m). The views across Kielder Water are stunning from this point. An exhillarating descent leads to Kielder Dam & the welcome refreshment point at CP1.

Cross Kielder Dam (which is the longest section of tarmac on the whole course!) to join the Lakeside Way multi user trail. Pass Tower Knowe visitor centre, descend to Cranecleugh Burn & follow the trail around the beautiful Bull Crag peninsula as it weaves its way around the inlets & bays. At Freya's Cabin the route leaves the Lakeside Way, crossing the C200 road to CP2 at Kateshaw Hill, before the steady climb up to the high point of the course at Scald Hill (367m).  

Follow the Lakeside Way to cross the historic Kielder Viaduct. Then enjoy the views across the stunning Bakethin Reservoir, a designated nature reserve. At Bakethin Weir there is a chance to fill up your water bottle at the hydration station before the final climb past Deadman's Cairn & Castle Hill. The final descent takes you through the forest onto the Duchess Trail running alongside Kielder Burn before returning to Kielder Castle.


For the 50k runners this is the finish location. For the 82k it's a chance to refuel at CP3, enjoy the support & head out onto the remaining 32k circuit. 

50k Ascent/Descent: 894m/895m

50k Time limit: 9hrs There will also be intermediate cut off times  at various locations.

Kielder 20 Mile/32k Trail Race: Although not an ultra distance, this is ideal if you're looking for a long distance challenge or maybe thinking of stepping up to an ultra in the future.

Incorporating everything the ultra includes...fantastic course, great support, well stocked feed station, tech t-shirt...just a few less miles...

The 20 mile route is a shortened version of the ultra. Starting from Kielder Castle, the course initially follows the same route featuring the superb sections of Castle Hill, Wainhope Bothy & Black Belling Fell...& of course the great descent to a well earned feed station at Kielder Dam.


This is where the route deviates from the ultra, returning along the Lakeside Way following the northern shoreline of Kielder Water. The ultra route is re-joined at Bakethin reservoir, a final steady climb back up into the forest is soon followed by a superb descent back to the finish at Kielder Castle.

Time Limit: 8hrs for the full route. There will also be intermediate cut off times  at Kielder Dam CP.

Please note: Sections of the routes are on the blue MTB trail which the Forestry Commission have given permission to use for the duration of the race. However we do not advise you to run this at other times when mountain bikes will be using the trail.

Hydration/Feed Stations: These will be located at each of the control point locations. Feed stations will be well stocked with our delicious homemade flapjack (vegan), chocolate brownies (gluten free), jellies, bananas, peanuts, mixed fruit & nuts, savoury rolls, crisps, squash, coke, water & hot drinks (tea, coffee, chocolate). To help minimize waste you will need to either bring your own water bottle, bladder, etc.


We generally use plant based compostable hot & cold cups at our events rather than plastic based ones. We're also trying to reduce the amount of single use disposable cups.

We will be providing all participants at the Kielder Ultra  with one of these reusable Eco Soft Cups as part of their race entry.

They're lightweight at just 10 grams, easy to hold, fold up & collapsible. So no excuse to be needing a cup handed to you whether it's at a hydration station or the finish area...


Drop Bags (82k & 50k): If you'd like some of your favourite nutrition or a bit of extra kit available on the course without having to carry it for the full duration, drop bags will be available for runners. These will be transported to to the feed stations at CP1 Kielder Dam Car Park (82k Runners) & CP2 (80k/50k Runners) & of course at Kielder Castle CP for the 82k run

This is a great event to bring along family & friends to offer encouragement & support & would provide a good day out in itself to see this amazing area. CP 1 at Kielder Dam is easily reached by vehicle or for the more adventurous by following the Lakeside Way cycle route. There are also numerous points along the whole course which are easily accesible from one of the many public parking areas. Additionally, with the 80k route returning back through the finish area at the 50k point, there's plenty of opportunity at this location. Click HERE for a downloadable Kielder Trails Guide.
