Headstock 500

About the Event

Embark on the definitive Welsh ultra-cycling odyssey: The Headstock 500, a formidable 500km journey unfolding from May 22nd to 25th, 2026. This self-supported bikepacking epic carves a relentless line through the soul of South Wales, demanding you conquer over 9,000 meters of ascent across the Cambrian Mountains, Brecon Beacons, and Black Mountains. More than a mere race, it’s a strategic expedition plotted around vital resupply towns—Abergavenny, Rhayader, Llandovery—that serve as lifelines for rest, refuge from legendary Welsh weather, or a dignified retreat. You'll carry your world on your bike, guided by GPS trackers that let loved ones trace your progress through remote valleys and over windswept ridges where self-reliance is paramount. Two meticulously stocked checkpoints offer crucial sanctuary with nutrition for all diets, punctuating the immense physical narrative with moments of human support. Beginning and ending at the vibrant Tiny Rebel Brewery Bar, this adventure promises not just a test of endurance, but a profound immersion into landscapes where beauty and severity exist in equal measure. Secure your place to write your own chapter in this story of resilience against an unforgettable backdrop.
