From the Richmond.com article:

For the third year, the Virginia Commonwealth University Police Department will host a silent run in honor of Memorial Day put on by veteran and officer Stephen Adt.
The 5K from the Stuart C. Siegel Center to the Virginia War Memorial serves as a somber reminder that the holiday is more than the beginning of summer or an opportunity for discounts at the mall.

“This is my way of kind of changing that,” Adt said.
The first year attracted more than 200 runners and Adt said he hopes the idea will gain traction in other cities to remember military men and women killed in war. Each year, a combat veteran leads the run carrying the American flag.
…
