The Big Brutal Swim

The Big Brutal Swim will take place at the stunning, glacially formed Llyn Padarn which is known for being sixth deepest lake in Wales. It's also home to a fish called the Arctic Char, a species left over from the time of the last Ice Age - although none of our swimmers have spotted one yet.
