Dyfi SWIMRUN

2022 DATE TBC
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.

SWIM DETAIL
  •  Swim 1 - 650m:  Around low water you will swim across the mouth of the Dyfi estuary to Ynyslas and the Dyfi Nature Reserve.
  • Swim 2 - 750m: You will swim back across the mouth of the Dyfi estuary from Ynyslas to Aberdyfi beach. The flood tide will have started so you will be swimming across a slight incoming tidal flow.
  • Swim 3 - 1200m: You'll swim from the Jetty past the village to Picnic Island - the flood tide will be assisting you. 
  • Swim 4 - 400m: The final swim is parallel to Aberdyfi beach with the tide once again on your side.
Expect a bit of bounce on the swims.
