500 portable toilets placed for Beijing Marathon

Five hundred portable toilets were placed for the annual Beijing Marathon at the Tiananmen Square on Sunday, 160 more than last year's, Beijing News reported.

There was a toilet at every 2 or 2.5 kilometers.

More than 30,000 people participated in this year's event. Apart from the newly set portable toilets, there were another 400 public toilets on the square, which means there was a toilet for every 33 participants.

Photos of last year's Beijing marathon runners answering the call of nature against a wall went viral on the Internet. Some runners said they were forced to urinate in public because there were limited portable toilets on the route.
