About Chillswim

Based in the Lake District, UK, Chillswim is involved with open water swimming worldwide.


The company's passion is purely open water swimming: outdoor swimming, wild swimming, open water swim races and supporting the growth of long distance swimming. 

Chillswim also offer guided long distance solo swims in the Lake District, which we think is the best place in the world for open water swimming.
