Kitty, Edie, Sophie, Emily, Hermione, Naomi and Bella have set themselves the ambitious target as part of the school’s 140th anniversary celebrations. They aim to complete the challenge over the course of a fortnight.

Sowenna will be Cornwall’s first adolescent mental health unit and is currently being built on the Bodmin Hospital site. The appeal is seeking funding for approximately £1.2 million to transform the unit from a high quality centre, to the best adolescent mental health unit in the country.

They said: “Many people are finding lockdown a particularly tough time, so we wanted to support young people our age who are struggling with their mental health.”

“The Sowenna Appeal funds equipment and lots of extras that the NHS can’t afford to give the specialist young people’s mental health unit. We have chosen to run 140 kilometres between us as the school is 140 years old this year so it seemed like a fitting way to celebrate that as well as help others.”

The girls will start their running this Friday. If you would like to follow their progress and support their cause, please click here to take a look at their Just Giving page
