About the event

Tal Y Lyn is a stunning glacial ribbon lake that lies at the foot of one of Wales' most iconic mountains, Cadair Idris, in the heart of Snowdonia National Park.

1 km - 2 laps of 500m 

1 Mile - 3 laps of 500m + 102m at the end (1602m)

Wetsuit or skins swimmers welcome. Please don't enter if you don't have previous experience of similar time spent in similar water temperatures.

REFUNDS: Entries can be transferred to other swimmers. No refunds. 

Please note that in the highly unlikely event that any swim is cancelled due to extreme conditions which include very high winds, ice, or dense fog impeding the view of the swimmers by the safety cover, we will endeavour to arrange an alternative swim, or date.
