Come and beat the Bull! Run the Kielder 10k around the stunning Bull Crag Peninsula of Kielder Water. If a full marathon is 20 miles too long, panic not, you can still enjoy the stunning scenery at the Kielder Marathon Weekend, with possibly the most beautiful 10k in the UK! You will be absorbed by your surroundings as you churn out the miles... meandering through the forests and heathland, this is a highly enjoyable race in a stunning location. Part of a fabulous weekend of events in this beautiful part of the country. Includes marathon, half marathon and run/bike/run.
