The Northumbrian Full & Half Iron-Distance Triathlon & Trails Runs

Sun 29th June 2025

A triathlon starts with participants running into the water under a starting arch that emits orange smoke. A crowd watches by the side, and trees form the backdrop. The sky is overcast, and the scene is filled with anticipation and energy. A group of swimmers in open water, wearing swim caps and wetsuits, competes in a race. Yellow buoys mark the route, and a forested shoreline is visible in the background under a cloudy sky. A cyclist wearing a blue and red jersey and white helmet rides uphill on a winding road surrounded by rolling green hills. Other cyclists are seen further back along the road. The sky is cloudy, casting shadows on the landscape. Three athletes run along a dirt trail in a lush, green forest. The runner in the foreground is wearing black sportswear, while the two runners in the background wear lighter, colorful gear. The sunlight filters through the trees, casting dappled shadows on the path. Two participants celebrate at the finish line of The Northumbrian event. They are raising champagne bottles and wearing medals, smiling joyfully. The banner and crowd barriers in the background highlight the festive atmosphere of the race's conclusion. Two people in athletic gear run on a gravel path through a lush, green forest with a large lake and rolling hills in the background. The sky is partly cloudy, casting dappled sunlight over the serene landscape. A scenic view of a winding road through lush green hills with several cyclists riding uphill.
