Rio 2016 Paralympics: Dame Sarah Storey and Hannah Cockroft win gold

Dame Sarah Storey and Hannah Cockroft both won their second golds of the Rio Paralympics, as GB surpassed their London 2012 total on day seven.

ParalympicsGB's nine golds on Wednesday took their tally to 43, improving on their 34 four years ago.

In a prolific evening session, they won 10 medals in the space of an hour in swimming and athletics.

Cockroft won the T34 400m in a world-record time while Storey was victorious earlier in the C5 cycling time trial.

She was one of three time-trial gold medallists for Britain, along with Karen Darke and Steve Bate.

Kadeena Cox set a world record of one minute 0.71 seconds to win the T38 400m in athletics, and Sophie Wells was victorious in the Grade IV dressage individual championship.

Britain had an excellent night in the pool with Aaron Moores pipping team-mate Scott Quin to gold for a one-two in the men's SB14 100m breaststroke and Michael Jones and Jonathan Fox taking first and second respectively in the men's S7 400m freestyle final.

Hannah Russell added to the haul with gold and knocked nine tenths of a second off her own world record in the women's S12 100m backstroke.

"I've been training for four hard years and I wanted to execute the perfect race, so to do it here is fantastic," said Russell, who also won a silver and two bronzes at London 2012.

Cockroft triumphed in the T34 400m on the track in a world record of 58.78secs, while her 15-year-old team-mate Kare Adenegan finished third for her second medal of the Paralympics.

The 24-year-old from Halifax won Saturday's 100m final and can make it three with victory in Friday's 800m final.

A golden Storey

"I wasn't 100% sure I had won [Wednesday's time trial]," she told Channel 4. "Your time checks are brilliant but until the announcer says it you're not sure."

The golden flat-mates

Darke, 45, went one better than her silver medal at London 2012 to win the hand-cycling H1-3 time trial, despite having to put her chain back on part way through the 20km course.

Her gold medal came minutes after her Paralympic Village flat-mate Cox had secured her third medal of the Games with her record-breaking T38 400m on the athletics track.

Cox, 25, has now claimed gold medals and world records in two sports in Rio, having won the track cycling C4-5 time trial in a best-ever time as well, while she also won T38 100m bronze.

She is the first British Paralympian to win two golds in two different sports at the same Games since 1984, when Peter Haslam topped the podium in both shooting and snooker.

Bate and his pilot Adam Duggleby won Britain's third cycling gold of the day with victory in the men's B tandem time-trial.

It was the pair's second gold of the Games after their tandem pursuit win.

Lora Turnham and her pilot Corrine Hall finished third in the women's B tandem time trial and there was also a bronze medal for 16-year-old Maria Lyle in the T35 100m final, whose class-mates watched from their school hall in the UK.

David Stone, who won gold at London 2012, took bronze in the men's tricycle T1-2 time trial.

He goes for gold again on Thursday in the road race (13:30 BST).

And Iran's Siamand Rahman set three new world records in 30 minutes in the men's +107kg powerflifting, winning gold with a lift of 310kg, or 75kg more than his nearest rival, or, according to Paralympics officials "the weight of a Siberian tiger".

GB still in medal hunt

In their quarter-final match, the GB men's wheelchair basketball team delivered one of their greatest ever performances at a Paralympics to beat world champions Australia 74-51.

Paralympic debutant Phil Pratt impressed again with 20 points, while team-mate Ian Sagar was the top scorer on 26.

They face Spain in the semi-finals on Thursday evening - just a few hours after the GB women bid for a place in their final by taking on the USA.

Back on the athletics track, David Weir cruised into the final of the men's T54 800m, winning his heat in a time of 1:37.30.

And Ukraine now await the GB men's 6-8 table tennis team after Will Bayley beat Spain's Jordi Morales to secure a place in the semi-finals.
