London 2012 Paralympics: Husband And Wife Take Gold, South Africa's Pistorius Breaks Record [SLIDESHOW]

The fourth day of the London 2012 Paralympic Games on Sunday saw competition for 60 gold medals in eight sports, including swimming, table tennis and sailing.

The event, which continues through Saturday, has so far seen China taking the lead with 71 medals, followed by Great Britain with 51 medals and Australia with 36.

South Africa's Oscar Pistorius dominated the men's 200 meter, setting a world record while maintaining a degree of humility.

"It is great to have rivals in the sport evolving," he said in a report posted on the Paralympics website after running 200 meters in 21:30 on two prosthetic blades. "You've seen the likes of Jonnie Peacock (100m) and Jerome Singleton (100m, 200m), Blake Leeper (100m, 200m, 400m) and Arnu Fourie (100m, 200m) pop up in the last year. It's phenomenal and it's great to see the sport evolving like that."

Great Britain has taken the lead in Paralympic cycling. Anthony Kappes and Craig Maclean took gold in the men's Individual B sprint on the last day of velodrome action, a day after mechanical difficulties caused them to fail to finish as teammates Neil Fachey and Barney Storey took gold. Storey's gold on Sunday came as his wife Sarah also took Gold in the C4-5 500 meter cycling time trial. This is Sarah's second Gold this year, capping her career total of nine.

While Britain has dominated cycling this year, China's Ji Xiaofei, Liu Xinyang and Xie Hao took gold and broke China's previous world record in the mixed C1-5 team sprint in the final cycling event.

So far swimmers have topped the list of medal earners this year.

For women's: Australia's Jacqueline Freney and American Jessica Long have each with three golds while New Zealand swimmer Sophie Pascoe has won two golds and one silver. Italian swimmer Cecilia Camellini is in third place with two golds and a bronze in swimming.

Topping male athletes as of Sunday: Belarus's Ihar Boki and Brazilian Andre Brasil each took two golds and one silver; Daniel Dias of Brazil took two Golds in swimming; and Ukraine's Yevheniy Bohodayko took one gold and two silvers.
