About the event

The sport of swimrun originated in the Swedish Archipelago, however an activity called "Jog and Dip" started in 1941 when Aberdyfi Outward Bound School was set up to train the Merchant Navy during World War II. Aberdyfi also became a training ground for a special troop of Army Commandos between 1942 and 1943.

To this day the Dyfi Estuary plays a big part in building resilience, teamwork and leadership skills in young people, through adventures in the wild with The Outward Bound Trust.

The Dyfi estuary is very special, now you can experience it in all it's glory.
