Central Massachusetts/Sturbridge have great biking trails

The goal of developers is to create a 50-mile network of trails along the historic Blackstone River's banks from Worcester, MA, to Providence, RI. Completed off-road sections in Massachusetts include a 3.5-mile segment from South Worcester to Millbury, and a 3.6-mile trail in Blackstone River and Canal Heritage State Park in Uxbridge. - Trail Map for the Park.
