Get set to see celebs including Caroline Flack, Donna Air and Zoe Salom carry a giant mascara wand down through the UK.
Cosmetics brand Benefit has organised a charity run from Scotland to London to raise awareness and money for Refuge – a domestic violence charity for women and children.
The 'Mascarathon' relay, which will take place from June 15-29, will start at Edinburgh and stop off at Newcastle, Birmingham, Cardiff and Oxford. It will end in Spitalfields, London.
TV presenter Caroline is fronting the campaign and will kick off the proceedings by running the first two miles from Edinburgh.
"I was thrilled to be asked to be an Ambassador for the Benefit and Refuge 'Mascarathon,' she said.
"With one woman in every four experiencing domestic violence at some point in her life, I hope the 'Mascarathon' highlights this terrible statistic and in turn raises much needed funds for Refuge.
"Please join me in supporting this invaluable initiative."
The two miles mark the two women a week who lose their lives to domestic violence.
Each runner will carry a giant 'They’re Real' mascara wand baton that will be passed from runner to runner.
