1. Boston – Charles River Trail
The largest city in New England, one of the oldest in the United States, and an international focal point for higher education and medicine, are features that make Boston a city of contrast and nonstop activity. It hosts the Boston marathon, held the third Monday of April since 1897, which makes it a major destination for this sport, and it is undeniable that Boston loves running. The Charles river trail is one of the most popular running routes in the city. It is difficult to avoid getting goosebumps when running here in the Spring: sailboats, flocks of wild geese, and multi-colored leaves in the trees make the landscape divine for your morning or afternoon jog.
