More than 70 riders are making the four-day trip. They're law enforcement from NC and Virginia.
The group stopped by the Fallen Officer Memorial in Greensboro Wednewday to pay tribute.
"They're all bicycle police officers from across our state on their way to pay their respects in Washington, and I think its a great honor to our community that they will stop here and pay their respects to our fallen heroes," said Assistant Greensboro Police Chief Christopher Walker.
The trip is 420 miles long. Thursday they'll ride through Richmond, Virginia and reach DC by Friday.
