Every kilometer covered can make a difference

This year, by signing up for one of these races, you have the opportunity to run for a cause greater than yourself: cancer research.

Cancer affects millions of lives every year, but every step you take in this race will have a direct impact. The money we raise will fund research projects on all types of cancer to prevent, detect, and treat this disease.

Whether you’re an experienced runner or a beginner, every kilometer counts.
