Get involved Fundraise for us Sophie's marathons 2024 My aim is to complete 4 half marathons in a year! I am fundraising for BTF as I have lived with hypothyroidism for 12 years. As I’d already completed 2 in the last year I thought I would do something different to encourage some more supporters so I decided to do it wearing butterfly wings as a symbol of the thyroid! Sophie completed both the Western Super Half marathon and the Great Bristol Run raising a total of £230 for the BTF.
