Rehoboth Beach is popular summer destination, and is especially known as a great beach for families. It’s also an excellent beach for running. Though not as wide as Ocean City Beach, one can run for 10+ miles along the beach, between Delaware Seashore State Park in the south and Cape Henlopin State Park in the north. The sand is fairly firm, especially near the water and around low tide. Enjoy a post-run cold one at the original Dogfish Head brewery.
Another key attraction in the popular Boardwalk, which runs for 1 mile (1.6 km) between Queen St. and Lake Ave. There are the usual boadwalk-y amusements, restaurants, and shops. It’s lit at night. Can be crowded.
Note: The running along the Rt. 1 is not great. Very busy road, sketchy shoulder, no views.
