Most consecutive days to run a marathon distance (treadmill + outdoor) - female

The most consecutive days to run a marathon distance (treadmill + outdoor) - female is 106, achieved by Kate Jayden (UK) from 31 December 2021 to 15 April 2022.

Kate's initial plan was to complete 100 marathon-distance runs, as this was roughly the distance between Aleppo, Syria and the UK, a route often covered by refugees in search of safety. She was not planning on making it a world record attempt but found the media attention around her potentially breaking the previous record helped promote her fundraising efforts, so submitted a record application. Throughout the attempt she raised money to help refugees with humanitarian aid and mental health care, as well as providing funds for food banks and hygiene banks in the UK. By the end of the attempt she had raised over £25,000 towards these causes.
