About Sam Day 37-Mile Challenge
September is Childhood Cancer Awareness Month!
Run-Walk-Move your way
Register to participate in our month-long challenge and complete 37 miles/hours/reps/laps/vinyasas, or however you’d like to move, in support of childhood cancer.
Why 37? Sam’s favorite number was 37 because he claimed it was the forgotten number. It was as if the number had feelings, was underrepresented among the more popular numbers, and needed some attention. Well, the Sam Day Foundation highlights this so-called forgotten number because it’s a little bit like the childhood cancers we focus on - somewhat neglected, and in need of attention and resources. When you engage with us, we'll advance childhood cancer research together.
Register. Move your way. Raise support for childhood cancer research!
