PLUNGING into cold water for a swim takes some doing.

But this Christmas there are 21 sites across the country where we can swim outdoors and then warm up after with a rum or a mince pie.

The Outdoor Swimming Society has a great interactive website where you can hover your mouse over a pink coloured snowflake to find festive swims.

Click on the snowflake and you get all the details and a link to the event’s website where you can read all about how to register.

Some events may require you to sign a disclaimer.
