Ben Proud shocked after breaking fourth British record

Proud dipped under 46 second on his leg of the men's 4x100m freestyle with a 45.97, the first time he has done so over that distance, having already set a record in the event earlier at the meet.

The 21-year-old also broke the British 50m butterfly record by clocking a 22.39 earlier in the day having already taken Mark Foster's 14-year-old short-course 50m freestyle British record on the opening day.

And Proud is convinced his exploits in the 100m freestyle will put him amongst the world's very best.

"I am totally surprised with that," he said. "I know that the top world rankings are at 46.0 right now so I am really pleased to be in the 45s. After that race, I had absolutely nothing left but that's the nature of the 100m freestyle.

"I'm also pretty pleased with my 50m fly British record from this morning. I was actually shocked, I thought I'd maybe dip under 23 so to get a 22.3 was a big surprise.

"I love the 50m fly, it's why I got into the sport, but it's not as relevant right now with the [Olympic] trials in three months.

"I'm going to take a few days off for Christmas and then I'll get back into it. I've got three months until trials and I am really looking forward to this next chunk of work."

Meanwhile, Aimee Wilmott won her fourth medal of the ASA National Championships by winning the 400m individual medley and Lizzie Simmons took 200m backstroke gold.
