About the race
The Kielder Marathon weekend comprises multiple timed events held around Kielder Reservoir on the Lakeside Way. Events on the weekend include:
- Marathon (trail distance 26.2 miles)
- Half Marathon
- 10K
- Gravel Duathlon
- Junior races for children aged 6 to 15 on Sunday 3rd October
The course is almost entirely off‑road on maintained trails with steep inclines and undulation; there are no public roads on the route. Course signage and marshals mark key junctions. Water stations are provided throughout the routes; High 5 isotonic drink is available from 10 km in the Marathon, Half Marathon and Duathlon. Toilets are available at the start/finish and at each water station. A secure bag drop marquee and first aid are provided; there are no showers or changing facilities.
Race entries include a timing chip attached to the race number for chip timing. Race information packs are posted from four weeks before the event and digital guides are emailed. There are dedicated car parks near Kielder Waterside (10K, Duathlon, Marathon and Juniors) and at the Dam for the Half Marathon. Free shuttle buses for runners operate from the car parks and the race number acts as the shuttle ticket. Spectator shuttles are charged and a return bus from Newcastle Central station is available for a charge of £13.50 per person. Allow at least 90 minutes from arrival at the car park to reach the start area.
Entry is not accepted on the day. The closing date is midnight on 29th September 2027 or when sold out. Entries are non-transferable and non-refundable; medical deferrals are considered with GP or physio evidence up to four weeks before the event. Time limits include a seven hour limit for the Marathon and a five hour limit for the Gravel Duathlon. Visit the organization's website for the most recent information.
