Get involved Current fundraisers Running the London Landmark Half Marathon 2024 for Florence - Dean Donate I will be taking part in the London Landmark Half Marathon for my daughter Florence. Florence has congenital hypothyroidism and has had more blood tests than we care to count and is still under the care of Great Ormond Street Hospital. There is still so much research still to be done for those patients like Florence which the British Thyroid Foundation help fund.
