Lake Vyrnwy Half Marathon

The Lake Vyrnwy Half Marathon circles a stunning reservoir in Wales' remote countryside. Runners follow the shoreline's perfectly flat loop road, with mirror-like waters reflecting ancient forests and distant mountains. September's early autumn conditions bring crisp air and golden light that showcases the lake's Victorian Gothic dam and fairy-tale tower. The traffic-free course delivers perfect surfaces for personal bests while offering tranquil natural beauty rarely found in organized races. The small but enthusiastic Welsh crowd provides genuine encouragement without overwhelming the peaceful setting. This hidden gem perfectly balances serious racing potential with spectacular scenery, creating a uniquely Welsh experience that combines accessibility with remote beauty in a race that feels both challenging and meditative.
