The RIDUM 2026

About the Event

Embark on an extraordinary adventure through East Wales, where each mile unfolds as a masterpiece in natural beauty and rugged terrain. The RIDUM invites runners to experience a unique blend of challenging landscapes and breathtaking vistas along its 30-mile course.
The journey begins at dawn when the valleys are still draped in misty silence. Scaling ridge-tops early on allows participants to enjoy panoramic views that stretch endlessly, with rolling hills and distant peaks framing your every step as you move through varied terrains throughout race day.
As morning progresses into afternoon, runners transition from open ridges where vast panoramas inspire awe, into dense woodlands cloaked in mystery. Ancient trees line the winding trails here, offering both an immersive natural setting filled with quietude and solitude. These sections of the route present a stark contrast to earlier parts of your journey while also providing a chance for deeper personal reflection amidst nature's grandeur.
Beyond being simply another trail race, The RIDUM offers participants exclusive access to some of East Wales’s most untamed wilderness areas rarely seen by outsiders. For both experienced runners searching out new challenges and those drawn towards lesser-known destinations rich in beauty and solitude, this event promises a memorable experience unlike any other offered across Britain's countryside.
Whether you’re pushing yourself against varied terrains or savoring the serene moments within pristine landscapes, The RIDUM presents an opportunity to connect intimately with nature while testing your physical boundaries. Join us for what will be more than just a race but rather an event that fosters community among those who share in enthusiasm about exploring trail running’s scenic and adventurous aspects alike.
For all runners seeking escapism into something truly captivating yet untouched by common tourism, The RIDUM waits to welcome you with open arms – allowing firsthand encounters of why this section of Wales continues enchanting visitors annually from across the globe. Don’t hesitate; secure your place now before spots fill up and miss out on crafting unforgettable stories fueled purely through passion for both trail exploration and stunning scenic beauty encountered along this pathless beaten track in East Welsh wilderness.
