Get involved Fundraise for us Katie's Royal Parks Half Marathon 2025 After being diagnosed with Graves’ disease and later becoming hypothyroid following treatment, I realised just how little is truly understood about thyroid conditions, despite how many people live with them every day. This experience motivated me to run the Royal Parks Half Marathon in support of the British Thyroid Foundation. I wanted to raise awareness of the challenges faced by those with thyroid disorders and to help fund vital research that can improve understanding, treatment, and ultimately, the quality of life for everyone affected.
