The Highland City Striders welcome you to explore the trails at the Assabet River National Wildlife Refuge in Sudbury, MA! The Race for the Refuge begins at the ARNWR Visitor’s Center and traverses the beautiful trails around the Refuge. The course will lead runners into this idyllic nature refuge, past ponds, through pine and oak forests, and alongside mysterious military bunkers.
We are runners in Hudson, Marlborough, and surrounding communities. Founded in 2002, our members meet several times weekly to run various distances for fun and to keep in shape! The Highland City Striders is a non-profit 501(C)3. All race profits will go to local charities.
We are also working closely with Friends of Woodlands and Waters, a non-profit working in partnership with the U.S. Fish and Wildlife Service to support our refuges. Check out their site to learn more and get involved!
