Build my planAbout this race
Sarcoma Stomp is being held in honor of Bo Arvin. The mission is to carry on the characteristics which made him loved by so many. We intend to preserve his memory of kindness, loyalty, humor, respect, faith and courage by bringing awareness to pediatric cancer as well as the underfunded research for treatment and a cure. The Bo Arvin Memorial Foundation will use 50% of our fundraising efforts to benefit the Children's Cancer Therapy Developmental Institute (CCTDI). It also supports 2 scholarships at Christ Our Rock Lutheran High School.
