Alberoni to Malamocco; from the vaporetto terminal north to the end of the island on Riviera Santa Maria Elisabetta/S. Nicolò (2.3 km); and the Lungomare Guglielmo Marconi on the eastern side, paralleling the beach for 3 km. To see some of the island’s shops, restaurants, and hotels, the wide Santa Maria Elisabetta leads the 700m from vaporetto stop to the beach on the other side of the island.
A beach along the Adriatic runs much of the length of the Lido. It’s not the perfect beach for running, but it is runnable, especially right next to the water. Some of the beach is private, but the two large public beaches (northern and southern side of the island) are long enough for a good run — but they can get very crowded!
