Get involved Heather's Cardiff Half Marathon 2024 Donate I am running the Cardiff Half Marathon in October this year to help raise funds for the British Thyroid Foundation. I am raising money for this charity as their information and support has, and is helping me through ongoing treatment of hyperthyroidism caused by Graves Disease. Running a half marathon will be a challenge but I'd like to help raise funds and more awareness of thyroid conditions and the effect it can have on people's lives. Let the training begin!
