#BooBrainCancer #PowerUpAgainstDIPG
How Does It Work?
Choose between a 5K or 10K challenge and complete it anytime, anywhere during October.
Last year, supporters from 19 states came together to raise more than $15,000 for research—and this year, we're determined to do even more.
What Do My Registration Fees Fund?
100% of event proceeds support pediatric brain cancer research through our Hope from Hailey program because children diagnosed with DIPG and DMG deserve better treatments, more options, and more tomorrows. Early bird registration is open now. Prices increase on August 1st!
