Swimming the Distance and making waves for lung cancer research and support.

What is Swimming the Distance?

Swimming the Distance is a challenge open to all ages and abilities. Simply register for free, pick the distance you would like to complete and head down to your local swimming pool (or open waters if that’s your thing!) at a time that suits you. We are there to support you along the way!

How it works

Create your own challenge! When you register, choose a distance, swim it solo or in a team and complete it in your chosen time limit. We ask participants to challenge themselves whilst fundraising to support those affected by lung cancer.


  • 1 mile – 65 lengths
  • 5 mile – 325 lengths
  • 10 miles – 650 lengths
  • 20 miles – 1,300 lengths
  • Create your own distance

Why take part?

Setting yourself a challenge can be the best way to reach a goal. This can help keep you motivated, focused and maybe even go above and beyond what you thought you were capable of. We’re here to support you & ensure you reach that goal successfully!

We understand life is complicated and often busy. With Swimming the Distance, you can make this challenge fit your own schedule easily by selecting your own distance and time limit that best suits you.

We want this challenge to be an extension of your passion for swimming. Join others across the UK all taking part. Share your progress, pictures and swap tips in our Swimming the Distance Facebook community.

Not only do you receive a medal and a sense of achievement for smashing your goal, but your support and fundraising will be helping those who need it most. You’ll be doing something you love and also supporting our patients and families affected by lung cancer along the way.

Don’t forget to start fundraising. Please visit our campaign page to set up your own fundraising page.

“I saw this challenge as an opportunity for me to hopefully regain my love of swimming (which I did!) and push myself to improve my fitness levels whilst raising money for a good cause. 

The mental health benefits were great – it gave me a sense of purpose and something I could do as “my own thing”.


“Sadly I lost my dad in September 2019 after a short battle with lung cancer, which is why I chose Roy Castle Lung Cancer Foundation.

I loved having emails to check in on my progress and to keep me motivated and I’d definitely take part in another fundraiser!”


“My Mum saw the challenge advertised and asked if I would like to take part and I was really excited to take part in a swimming challenge.

I wanted to take part as I love swimming and am working towards my Level 10 swimming.

I enjoyed knowing how many lengths I was swimming and that it was all going to a great charity.”
