Kids can join the fight against cancer! Join us on Saturday, May 19 at the Orange County Great Park. Children 3-11 years of age can run/walk the 5K with family at 9:00 a.m., join the children's ride at 12:00 p.m., or do both. Children also have the opportunity to fundraise for cancer research. Children receive an official Anti-Cancer Challenge medal and complimentary lunch. Click here to check out the Challenge day schedule.
