I have chosen to walk 55 miles over four weeks in memory of someone I have lost to cancer. Help me make a difference by sponsoring my challenge, and supporting the bone and soft tissue cancer charity, Sarcoma UK. Thank you for helping me make a difference. At Sarcoma UK, we know too well what it is like to lose a loved one to cancer - any kind of cancer - it's why we are determined to ensure that everyone gets the best treatment, care, information and support available and to create the treatments of the future.
