Rio 2016: Jade Jones focused on Olympic Taekowndo defence

Jade Jones won a gold medal at the inaugural European Games in 2015

Olympic Taekwondo champion Jade Jones says defending her title this summer will be a daunting prospect.

The Flint fighter was 19 when she beat then world champion Fuzhou Hou to win -57kg gold in London four years' ago.

Jones, 23, has been included in Great Britain's four-strong taekwondo squad for Rio 2016 and has targeted further success.

"It will be daunting because you've got to be the best you've ever been just on that one day," Jones said.

"It's about being mentally on it on the day. You might wake up feeling a bad day, but no matter what you need to be on it and that's the important thing.

"There are eight people in my weight that could win the gold medal but I'm confident if I'm relaxed on my day."

The -57kg world number one has won a World Grand Prix and two European titles since her success in 2012.

Jones is determined to retain her title but admits it has been hard to stay motivated following her win in London.

"For me the pinnacle and my goal was always the Olympics," Jones told BBC Wales Sport.

"Winning the Olympics at 19, obviously it was going to be hard.

"I came back to training and big men were trying to beat me up because I was Olympic champion.

"It had been hard with motivation but I'm really hungry for a gold medal and hopefully I've come into peak just in time again."

Despite fears over the Zika outbreak, Jones is happy to travel to Rio for the Olympics.

Golfer Rory McIlroy has pulled out of the Games because of concerns about the virus and defending men's tennis champion Andy Murray will seek medical guidance before travelling to Brazil.

The International Olympic Committee has said it sees no reason to delay or move the Games because of the mosquito-borne virus, which is linked to serious birth defects.

"All I focus on is getting my gold medal," Jones added.

"It's not going to stop me from going and trying to get my gold medal, so that's all I can think of.

"We trust the GB team will give us the best advice and the best vaccines we can possibly have."

Bianca Walkden (+67kg), Olympic bronze medallist Lutalo Muhammad (-80kg) and heavyweight Mahama Cho (+80kg) have also been included in the team.
