United in Blue
From March 1-14, 2026, Fight Colorectal Cancer will transform the National Mall in Washington, D.C. into a powerful visual reminder of a growing crisis: By 2030, an estimated 27,400 people ages 20–49 are projected to be diagnosed with colorectal cancer.
Turning the National Mall Blue to Demand Change
United in Blue is Fight Colorectal Cancer’s bold, annual installation on the National Mall—an unforgettable display of 27,400 blue flags, each one representing a young life that could face a colorectal cancer diagnosis in 2030. It is one of the largest and most visible colorectal cancer awareness events in the country, bringing survivors, caregivers, loved ones, advocates, clinicians, and lawmakers together in a shared mission.
United in Blue Schedule
Sunday, March 9 — Installation Day
Hundreds of volunteers will gather on the National Mall to place 27,400 blue flags—one for every young adult projected to face colorectal cancer in 2030. In 2025, over 400 volunteers completed the installation in just under eight hours. This year, we return with even more determination.
Tuesday, March 11 — Rally Day
Colorectal cancer survivors, caregivers, loved ones, members of Congress, and special guests will come together for the United in Blue Rally—a moment of remembrance, resolve, and collective action.

Alongside the installation stands the Wall of Champions, a place for families, survivors, and caregivers to honor those who have faced colorectal cancer—including those we’ve tragically lost. It is an intimate space for reflection and a reminder that this fight is deeply personal.
“The flags are an incredible, powerful representation of what we face as a colorectal cancer community.” — Molly McDonnell, Fight CRC
