Cardiff Half Marathon

Epilepsy is a common health condition, that too many people know nothing about. Most people see epilepsy as an inconvenience. Flashing lights and falling over. Not an unpredictable and potentially fatal condition. Epilepsy Action is creating a world without limits for everyone affected by epilepsy, connecting people with others, and providing support and information you can trust. We’re calling out the misunderstanding, prejudice and barriers that stop people with epilepsy living their best life. Epilepsy says stop. We say go.
