The Welsh Winter Swim

29th February 2020

Set in beautiful Llyn Padarn, Llanberis with views of snow covered Mount Snowdon, The Welsh Winter Swim will include short individual races of 50-250m and a tough 500m endurance challenge. You may enter single or multiple races. Please remember the water will be very cold (around 1 - 7ºC) and it is essential that you acclimatise to cold water swimming sufficiently before taking part in these races.

 Entries for wetsuit and non-wetsuits are available but please be aware that wetsuit wearers will not be eligible for prizes except for 'Best Hat of the Day'

 The Races

Challenge = Swim fast or chill out and chat - swim any stroke you like.
Head up breaststroke = the traditional cold water swimming style allowing swimmers to compete in cold conditions without getting brain freeze! The rules are simple – you must ensure that your eyes do not go below the water level at any time during the race. Swimmers are encouraged to wear a warm hat for this race, or get crafty and create their own head wear – the more wacky the better. There will be a winner of 'Best Hat of the Day' plus an extra special prize for an 'Environmental' theme hat of the day! (Please consider the environment when making/purchasing hats and make sure that any hat you wear will not cause any pollution to the lake - no bits that can fall off or glitter etc - thank you!)
