Great Britain's three-time World Taekwondo champion Bianca Walkden is pushing to become the "best ever female heavyweight" in the lead-up to the Tokyo 2020 Olympic Games. 

The 28-year-old has already secured her place for Tokyo 2020 next summer. She said: "I just want to keep pushing to be the best ever female heavyweight. 

"When you hear about the rivalry in taekwondo, I thrive off it. Everyone is there in front of me to stop me getting where I want to be - so bring it on."

She is one of six GB fighters competing in the World Taekwondo Grand Prix series in Moscow this weekend. 

Walkden won her third world championship title in Manchester earlier this year. 

The Olympic bronze medallist added: "Not many people in taekwondo can say they've done that and to do it just before an Olympics is an amazing opportunity.

"I can't wait to go out there next summer and give everything I've got and die trying for an Olympic gold medal."

Compatriot Jade Jones and the two-time Olympic champion has also qualified for Tokyo 2020 and is set to compete for Team GB at the Grand Prix. Double European champion Lauren Williams will also be competing.
