A half iron-distance triathlon AND ultra trail runs, in and around the stunning and challenging Kielder Water and Forest
The ultimate endurance test will be open to a limited number of individuals and teams to conquer the beautiful waters, forests and terrain that give Northumberland and Kielder its unique character. The summer of 2027 will welcome the sixth edition of an event which combines scenery, fortitude, adventure, and achievement. Everything it takes to be recognised as a NORTHUMBRIAN.
Our first five editions included a full iron-distance triathlon, however, we are sad to announce the full iron-distance triathlon will not be held in 2027. Due to lack of numbers in this distance for the last couple of years we are unable to justify the additional infrastructure, staff, volunteer and planning time that goes into a full iron-distance event. If demand does return for this distance in the future we are open to holding it again. We will always take feedback from our participants and welcome those who would like to compete in the full distance again to get in touch.
