Sam Day 37-Mile Challenge
Walk, run, ride or roll 37 miles in the month of September. Honestly, you can move your body in whatever way you wish, anywhere in the country. The goal is to bring awareness and resources to childhood cancer research. Kids with cancer need us to make some noise and ignite hope. Let’s make it fun and impactful. Your registration fee includes a 37 Mile Challenge tshirt (either dri-ft or tri-blend), sticker, shoelaces, and a conversion chart and calendar. Why 37? Sam’s favorite number was 37 because he claimed it was the “forgotten number”. SDF uses the forgotten number because we want to draw attention to the forgotten cancers, the ones that don’t get as much research attention.
