This event has passed. Congratulations to all the participants. Get race results and photos.

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.

This is held at the same venue as The Brutal Extreme Triathlons and therefore great preparation for the event later in the month. This event is open to wetsuit and non-wetsuit swimmers. There will be separate categories for wetsuit and skins swimmers.

The distances available are 2.5k, 5k and 10k.

    My daughter who is 16 wants to enter either the 2.5 or 5 k race. Is this event open to children or just adults?
