A couple from Westbury-on-Trym who lost an unborn baby to complications from twin to twin transfusion syndrome have raised enough money for research into the condition.
Lucy and Matt Britton made the "heartbreaking" decision to separate their unborn twin babies with surgery, as both were at risk from the rare condition, in which the twins share a placenta and blood passes between them.
They were devastated to lose one of their babies, but have since started the charity The Capella Foundation, to try and spare other families the same pain.
Each year they organise a brutal exercise challenge to raise money for research at St Michael's Hospital in Bristol so that doctors can begin to understand what causes these complications and fight for future pregnancies.
They have now raised over £50,000 - and a two-year project studying mothers expecting twins begins in August.
