Calories Against Childhood Cancer. On 21/02/2024 beautiful Aria Zimmermann lost her life to cancer. This gorgeous, generous, and joyful little girl did not deserve to spend her little life-fighting cancer and finally succumbing to this horrendous disease. On June 22nd which would have been Aria's 6th Birthday, CrossFit Marrickville will run a charity WOD to raise as much funds for Bear Cottage and Zero Childhood Cancer as funding for these valuable charities is overwhelmingly scarce.
