We're running the Medoc marathon in France to raise awareness and funding for breast density research. Breast density relates to the white and bright areas on a mammogram. It's a breast cancer risk factor and can also hide tumours on a mammogram because the white density looks the same as the white cancer. Like trying to find a polar bear in a snowstorm.

We'll be helping raise awareness of breast density by running the marathon in polar-bear-in-a-snowstorm themed costumes. Check here for updates!
