Jerusalem's winding streets will be closed Friday for an historic event: the participation of over 25,000 people, from 54 different countries, in the annual Jerusalem marathon. 

The competitions include a full marathon, a half marathon, a 10 kilometer run and a 5 kilometer run. Mayor Nir Barkat and Gilad Shalit, the soldier released from Hamas captivity in 2011, are participating in several of the events. 

At least 2,500 runners flew into Israel from abroad for the marathon run, and hotels in Jerusalem report that over 10,000 rooms have been booked, leaving no vacancies. At least 50 different press organizations have flooded the Holy City to record the city's fourth annual run.
