The Big C Swim

12 October 2022 - 15 July 2023 Heathwood Swimming, CF10 4LQ

NEW for 2022!

In partnership with Ambassador Dave Tonge, Heathwood Swimming and MUUK Adventures, Velindre is proud to announce a brand new challenge created for beginner swimmers.

With the help, support and encouragement of a team of professional swimming coaches, we will take you from SOFA to SEA in time for the main MUUK event in Solva on 15th July 2023. You can read more about ‘The Green Monster’ Solva Swim here.

So what’s the connection to Velindre?

The challenge is called ‘The Big C Swim’ as we are encouraging applicants who have a connection to Velindre or cancer in general. In addition to ‘jumping in at the deep end’, you will also be raising vital funds for our Hospital Of Hope and in turn, making a huge difference to the lives of cancer patients in Wales.

Throughout your swimming journey, we will also be capturing your story to hopefully raise awareness of the work of Velindre and also to inspire others to take the plunge in their own way, whether that be swimming or another challenge.

“If you’re up for a challenge which will inspire others and also raise vital funds for an amazing cause then get In touch with us and share your story.

Sea Swimming is something everyone should experience in their lifetime and our coaches at Heathwood Swimming will help you gain the confidence and skills needed to achieve your goal.”
