Dyfi X Swimrun

The Dyfi X Swimrun takes you deep into the heart of Wales, where land and water merge into one relentless challenge. Covering 17km, this race consists of 3.5km swimming and 13.5km running, divided into six swims and seven runs. Inspired by the original ÖTILLÖ format, it demands resilience, teamwork, and grit as you navigate rugged trails and open water. This event is rooted in the rich history of the Dyfi Estuary, where for nearly 80 years, The Outward Bound Trust has shaped adventurers through wild endurance challenges. The Dyfi X Swimrun embraces this legacy, offering a raw, untamed experience for athletes seeking the ultimate test.
