Each year, the Greenway Challenge athletes run, paddle and bike on a course designed to bring you through one of the most beautiful and historic regions of New England, the Blackstone River Valley National Heritage Corridor located between Worcester, MA and Pawtucket, RI. Athletes can compete as solo racers or in teams of 2-4 and 5-8, with each team member competing in at least one segment along the course. This annual race is one of New England's premier adventure races!

The mission of the UniBank Greenway Challenge is to promote the recreational quality of life in the Blackstone River Valley. A program of the Whitin Community Center, presented by UniBank and supported by other partner organizations, the Greenway Challenge supports the development of new programs, purchase of additional equipment, and facility renovations for the members and guests of the Whitin Community Center (WCC).
