Join a people-powered celebration of greenways and rivers.

As the signature event and grand finale of the East Coast Greenway Alliance’s 25th-anniversary celebrations, the East Coast River Relay is the largest program in our organization’s history. The River Relay offers a series of organized walks, runs, and bike rides along the 3,000-mile East Coast Greenway from Calais, Maine, to Key West, Florida, from August 24 to October 30. Through the River Relay, the East Coast Greenway Alliance aims to raise greater awareness of the Greenway as a key linear park offering access to nature and watersheds for the 60 million people living in our corridor.
