The 25th Annual Rainbow of Heroes Walk to benefit the Duke Pediatric Transplant and Cellular Therapy Family Support Program is a midday fundraising event at Duke's Center for Living where families, friends, and volunteers gather to walk around the athletic track, and do laps in celebration and remembrance of loved ones that have undergone a stem cell transplant. There are many family-oriented activities scheduled throughout the morning, including carnival games, an inflatable slide, auction, Wall of Heroes with photographs, stories, and memoires of patients and families, and a catered lunch.
