Swim for a cause. Make every mile matter

Right now, nearly 3.5 million people in the UK are living with cancer, and they need support more than ever. You can make a real difference - one length at a time.

We do whatever it takes to get every person with cancer the best support today and spark a revolution in cancer care for the future.

Join Swim It this summer for Macmillan and take on 21 miles over June and July. Whether it’s in your local pool or lido, every swim helps fund vital Macmillan services.

Raise £250 and be part of something bigger. You don't have to be an Olympic swimmer to make a herculean difference - swim at your own pace, in your own way.
