Now in its 4th year, Swim Serpentine is a one-day open water swimming festival staged in the heart of London.

Our swimmers will be taking on a 2 mile event in this the largest open water mass participation event in the UK

10 million people in the UK suffer from diseases in which mitochondrial dysfunction is believed to be involved, while every day in the UK a baby is born who will develop mitochondrial disease. The disease is debilitating, there is no cure and lives are cut far too short. The Lily Foundation's ultimate aim is to one day find a cure for mito.

As a charity dedicated to fighting mitochondrial disease, our mission is to support people whose lives are affected by the condition, raise awareness and fund research into its prevention, diagnosis and treatment.

Please support our 2019 Swim Serpentine Team and together we will make a difference.
