Organiser's Description
Join us for our 4th annual BOO! BRAIN CANCER BIKE CHALLENGE AND 5K, and help us raise funds for pediatric brain cancer research and patient support!
Brain cancer is now the leading cause of death by disease in children and Diffuse Intrinsic Pontine Glioma (DIPG) accounts for approximately 50% of those deaths. There is no cure for DIPG and the majority of kids will survive 9-11 months following diagnosis. _NO CHILD DESERVES TO BE GIVEN A DEATH SENTENCE. HELP US RAISE AWARENESS AND CHANGE THESE SCARY STATISTICS._
The Boo! Brain Cancer Challenge has several participation options. We are continuing the virtual bike challenge for 2026, in which participants choose to complete 25 or 200 miles during the month of October. We also have a virtual 5K walk/run challenge. We encourage you to track your miles on our race page and post pictures in our Facebook group!
