The Bank of America Chicago Marathon is a world class running event returning to the streets of Chicago on Sunday, October 12, 2025.

Did you know every other day in the UK a baby is born who will develop mitochondrial disease? Each member of Team Lily will be running for them and the 10 million people in the UK who suffer from diseases in which mitochondrial dysfunction is believed to be involved. This disease is debilitating, there is no cure and lives are cut far too short. The Lily Foundation's aim is to one day find a cure for mito. As the UK's leading 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 Chicago Marathon Team and together we will make a difference.
