The Donor Dash is a 5K run/walk to honor the lives of organ and tissue donors, celebrate the lives of organ and tissue recipients, and recognize those who continue to wait for a lifesaving transplant.
We are excited to be at Washington Park for the 27th Annual Donor Dash on Sunday, July 19, 2026!
Ways to HONOR CELEBRATE & RECOGNIZE at Donor Dash:
THE DASHBOARD: As a participant, you can share a photo and a short message highlighting your reason for participating or your personal connection to donation and transplantation. These photos and messages will be displayed throughout race morning, honoring, celebrating, and recognizing the stories and inspiration behind our Donor Dash community. Learn more about the Dashboard here!
RIBBON CEREMONY: Please attend the on-stage program starting at 9:30 a.m. on race day to hear inspirational stories and recognize the different connections around organ, eye, and tissue donation. On race day, you can grab your ribbon near the finish line or at the ribbon tent near the expo area. The ribbon connection colors are below.
