Dyfi X SwimRun

Dyfi X SwimRun 2023

All take place in the UNESCO Dyfi Biosphere.

The sport of swimrun originated in the Swedish Archipelago in 2006.

Since 1941 the Dyfi Estuary has played a big part in building resilience, teamwork and leadership skills in young people, through adventures in the wild with The Outward-Bound Trust.

Dyfi Swimrun is inspired by history, the Outward-Bound spirit, and the original race format from ÖTILLÖ.
