About this race
Support our 4th annual event fighting pediatric brain cancer, a leading cause of death by disease in children. No child deserves a death sentence. The BOO! Brain Cancer Challenge offers options to bike or walk/run virtually throughout October. Funds raised go directly to Princess Hailey's Hope Foundation, supporting vital research and providing "Hugs from Hailey" care packages to kids battling the disease. Snag "Childhood Cancer is Boo Sheet shirts" to show your support.
