Lui wins gold for China

China's Liu Hong won the women's 20 kilometres walk to hand the host country their first gold medal at the Athletics World Championships on Friday in Beijing.

Liu headed a Chinese one-two in the walk with countryman Lu Xiuzhi finishing second.

On a very hot day in Beijing the two started off at a brisk pace and built up a huge lead, Liu eventually winning gold with a time of 1:27:45.

Lu finished a second behind followed by Ukraine's Lyudmyla Olyanovska 28 seconds behind in third.

"There was a lot of pressure but I was confident in this mission," said Liu.

"When we hit the front at the start I didn't think we were going that quick but nobody followed us, so we just carried on. It's a dream to win the gold," she added.
