Organized by one of the UN organizations and as part of the summergames for children: a marathon in Gaza strip.
The children ran it as a relay and 9 adults completed the entire marathon. Winner of this first ever marathon in Gaza strip is Nader al-Misri in 2:42:47. He is in training for the olympic marathon of London 2012.
Check out the numbers on the runners shirts. Looks like everyone brought his own number along.

Sorry but the video is partly in Dutch but it gives a nice impression of the event.
