Britain's European and Commonwealth 100m breaststroke champion Adam Peaty has warned his rivals the pressure of being at the top will only make him stronger as he chases Olympic gold in Rio next year.

Peaty takes to the blocks for the British Championships on Tuesday, hoping to build on a superb 12 months that has seen him clinch six European and Commonwealth gold medals and set a world record in the 50m breaststroke.

This week's competition at the London Aquatics Centre will also serve as trials for the World Championships in Russia later this year and Peaty insists he has no problems with being the man to beat.

"Last season my coach and I wanted to be the hunters and the silent assassins, but the tables have turned," Peaty told Press Association Sport.

"The world record has put me on that pedestal now and I'm happy to be that person everyone wants to beat, that's where everyone wants to be.

"I like to defend my titles - that's what defines a champion - it's not just about winning it, but living with it and defending it.

"I try not to think about last year now too much. We have to take what we can from it and it's going to be hard to replicate that this season.

"But I'm fitter this year and much, much stronger. I've got all these areas I've been improving and hopefully I can show that this week."

Peaty will compete in the 50m, 100m and 200m breaststroke as he looks to lay down another marker ahead of the Games in Rio next year.

The 20-year-old, who is coached by former world, European and Commonwealth medallist Mel Marshall, did not compete at London 2012 and admits winning Olympic gold is already on his mind.

"It's mad to think London was only three years ago," Peaty said.

"Everyone trains for the Olympics, if they say they're not they're lying.

"It's always in the back of my mind, some days more than others, but it's there.

"I don't like to put too much pressure on myself but I'd like to bring it back for my country and for my coach.

"Mel has been there and done it, she's explored everything that needs to be explored in the sport.

"She keeps me grounded when I need to be grounded but before every race she knows those important few words to say that help me get my game head on."

Also eager to make an impression this week is reigning European and Commonwealth 400m individual medley champion Hannah Miley.

Miley, who was born in Swindon but is Scottish by nationality, is yet to replicate her success at an Olympic Games, having finished fifth at London 2012 and sixth at Beijing 2008.

"If I qualify for Rio, it won't be a matter of third time lucky, it's third time being better prepared," Miley said.

"Leading into Beijing I came down with a throat infection and the preparation for London wasn't great either as my event was on day one and the team were being dragged everywhere beforehand.

"It would be extra sweet now to come away with a medal in Rio but even if the Olympics forever elude me I can still say I went to three Olympic Games and that's very special.

"When I got my gold in Glasgow you stand there with it in your hand and think all the hard work was for a little piece of metal.

"But it's more than that - it's about the journey that got you there and the stories along the way."

Adam Peaty and Hannah Miley were speaking at the launch of the Arena Powerskin - The Carbon Series. For more information visit www.arenawaterinstinct.com.
