9,000 runners will take part this picturesque half marathon on Sunday 15th March 2026.

They will run through traffic-free streets in the heart of Bath, the UK's only World Heritage City, and experience the electric atmosphere on the course.

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 is 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 2026 Bath Half Marathon Team and together we will make a difference.
