(Thanks to Israel21c) Sovev Turki Elite on Sep 25 is Israel’s largest cycling event with 30,000 cyclists and over 100,000 spectators. The longest route for experienced cyclists covers 43km around Tel Aviv with shorter routes for active families, beginners and roller-blades. The Ayalon freeway becomes a cycle track.
