SUNNINGDALE'S Sophie Christiansen and partner Natasha Baker both completed the double treble as ParalympicsGB again showed their dressage determination in Rio.

Former Charters School pupil Christiansen and Baker had already retained their individual titles from London 2012 and joined forces with Sophie Wells and Anne Dunham to win team gold.

And they completed another Games to remember with victories in their respective freestyle competitions.

Christiansen, 28, has now won eight career Paralympic golds in four Games appearances and paid tribute to her team-mates and horse Athene Lindebjerg.

She said: “I am so proud of all my teammates. They've done so well and I'm just thrilled.

"This year has been so up and down so to even get here was a feat in itself.

"Athene (Lindebjerg) is just a young horse. I didn't know how he would react, but he felt so relaxed with me, so I knew we could do it.

"It is tough, I'm not going to lie but you need that drive and determination that I think that Paralympics shows."

Christiansen, who lives in Maidenehad, also signalled out team-mate Dunham, 67, who won a second individual silver in the grade Ia class freestyle.

"I remember when I was 13 and started out in the sport," she recalled. "She was always this top rider that I thought I would never beat.

"I was down seven, 10% below her. I thought I would never do it. It's thanks to Ann that I'm as good as I am now.

"Having that rivalry is really, really healthy. The fact that she is British is even better. It means we get the one, two."

Baker’s victory was extra emotional considering it will be her last appearance on Cabral, a horse named after the explorer who discovered Brazil.

The London-born rider even admitted to feeling sorry for ParalympicsGB’s rivals after winning 11 equestrian medals in total, including seven golds - six more than nearest nation Holland.

She said: “For our last test together, I just think it was magical and amazing. He deserves to go out with a bang. Five gold Paralympic medals, three here, two in London - he's a legend.

"I feel sorry for hearing our national anthem so many times. It's just incredible and we all feel so good.

"It's been an amazing competition. I think even more successful than London for our team.

"All that work has paid off. We have the best team in the world around us and there's a great spirit in the camp."

Earlier, Lee Pearson had won gold in the grade Ib freestyle and Wells had taken silver in the grade IV class.
