It’s also the only triathlon in the UK to cross two countries, with an unforgettable 90km cycle route heading over the border into Scotland for some of the most spectacular riding you’ll find anywhere.

Set in the wild heart of Kielder Forest, the weekend also features two stunning UTMB Index ultra trail runs with truly epic views. Conquer the challenge, embrace the landscape, and earn the right to call yourself a true Northumbrian!
