World Para-swimming Championships: Tully Kearney breaks 22-year-old world record

Kearney is competing at her fourth World Championship

Britain's Tully Kearney broke a 22-year-old world record to win gold in the S5 200m freestyle on day six of the World Para-swimming Championships.

Kearney finished in a time of two minutes 42.36 seconds to retain her world title in Madeira, Portugal.

Double Paralympic champion Maisie Summers-Newton won her third world title of the week with victory in the SB6 100m breaststroke.

Britain's third gold of the day came in the mixed S14 4x100m medley relay.

Bethany Firth anchored the team to win by just 0.01secs for her fifth title of the week.

Kearney, who has been getting treatment for a shoulder injury, smashed Beatrice Hess' previous world record, set by the French Paralympian at Sydney 2000, by 2.25secs.

The win is Kearney's second gold of the championships after her 50m freestyle success on Sunday's opening day of competition.

"That is just absolutely insane," she said. "I've been adapting my training a bit because of my shoulder. We kind of changed it up and did something slightly different to Tokyo with less miles but more intensity.

"I wasn't quite sure what would happen over the longer distances but obviously it's paid off and I just can't believe how quick I went.

"I've really struggled recovering between heats and finals and if it wasn't for the British Swimming medical team I wouldn't have been able to do that so I'm really grateful to them."

She will bid for a hat-trick of titles in the 100m freestyle on Saturday.

While Kearney and Summers-Newton were comfortable winners of their races, the relay team of Firth, Poppy Maskill, Scott Quin and Reece Dunn ensured plenty of drama with Firth getting to the wall just ahead of Australian Madeleine McTernan.

"This team was amazing," said Firth, who took over in third place, three-and-a-half seconds back, but came through brilliantly.

"With so many S14s, just to make this team is such a privilege and I didn't want to let any of them down. We went for it and got gold. I couldn't have given any more and was so glad to touch first."

Dunn, who won five medals, including three golds, in Tokyo, has found the going tough this week: "You always swim well for relays, they're a bit more exciting and give you a bit more adrenaline.

"We knew it was going to be close coming into the finish but Bethany on that last leg was amazing. When I saw the touch it was pandemonium."

There was also bronze for Britain's Hannah Russell, Matthew Redfern, Scarlett Humphrey and Stephen Clegg in the mixed 4x100m freestyle 49pts relay.
