Join us for The Screaming Pumpkin through Springdale Cemetery. Chills and thrills will keep you motivated as you run or walk through our 2 mile walk, 6.55 mile run, half marathon, full marathon, or full marathon relay! Run or walk if you dare. Once you start, there is no turning back. The half, full, and relay are prediction runs. Finish before 10PM! The winner is the closest to 10PM without going over. The Yellow Bear Foundation is a non-profit organization empowering communities to spread awareness and fund research of Primary Immunodeficiency (PI). With more research, we hope to help create a future with improvement of diagnosis, treatment, and quality of life of persons with PI.
