This is another nice variation from the center of Nantucket, this to the rougher Surfside beach on the island’s south side. It’s a good, straightforward nearly 7-mile run, much of it on bike paths.
Start in Nantucket Ctr. and run out York St. or Atlantic Ave. (or road of your choice) to Surfside. Join the bike path, and run 2.5 miles to Surfside Beach. Take a dip on a nice day! For the return, do an out and back, or for variation, head east on Nonantum Ave. from the beach, LEFT in Boulevarde, and RIGHT on Fairgrounds Rd. for a 1 mile along the bike path, then LEFT on Orange for the final mile.
Note: quite open– be aware of sun.
