Regrettably, we cannot allow friends or family to come and watch or support at he lakeside as it causes a distraction for our lifeguards on duty,  and our swimmers very much value the solitude this unique environment offers. Guest’s however are very welcome to wait at the Sheep Barn Cafe (normally open Friday to Saturday).


The cold water stimulates your nervous system, producing a feeling of relaxation, contentment, and ultimately, a better night’s sleep. 

Regular swimmers at the lake use swimming as part of their weekly downtime routine for to switch off and enjoy some rest and relaxation.

Swimming in cold water also boosts circulation, as the colder temperature causes blood to rush to your organs and makes your heart work that bit harder.

Increased metabolism

Your body automatically tries to work harder to keep warm, and so the colder the water, the more calories you’ll burn as your body fires up your metabolism.

Wet suits are recommended when the weather gets that bit colder.

We are one of the few locations in Northamptonshire that offers swimming  year-round, with at least five sessions per day.

Happier mood

Cold water causes your body to release endorphins – the natural high that helps us fight depression. Your system will also generate dopamine and serotonin, which make you feel good and reduces any stress – a powerful way to inject some happiness into your routine.

There is also a strong sense of community between the lifeguards and swimmers, so if you’re new to swimming with The Falcon, be sure to interact with us on the Open Water Swim Facebook page for the latest information and tips.

Boosted immune system

Being submerged in cold water for even short periods of time is enough to make your system produce white blood cells and antioxidants, which is perfect for boosting your immunity to viruses.
