Set within the magnificent UNESCO Dyfi Biosphere, Dyfi X covers a breathtaking 17km route on the periphery of Snowdonia National Park. Participants will face a total of 3.5km swimming and 13.5km running, strategically divided between six swims and seven runs.
For almost 80 years, the Dyfi Estuary has been instrumental in fostering resilience, teamwork, and leadership abilities in young individuals.
