Tokyo 2020: Sky Brown, 11, perfecting new move for Olympics

Eleven-year-old skateboarder Sky Brown is hoping to perfect a new move in her bid to become the youngest-ever British summer Olympian at Tokyo 2020.

Brown says she is practising a 'backside 540', which involves spinning one-and-a-half times towards your toes.

She all but guaranteed herself Olympic qualification with a bronze in September's Park World Skateboarding Championships in Brazil.

"I have a lot of tricks I'm working on," Brown told BBC Radio 5 Live.

"I can do a 'frontside 540' [spinning towards the heels], but I'm trying to learn backside."

The World Championships medal means Brown will be seeded for next season's Olympic qualifying events, so if she takes part and remains injury free she will essentially qualify for Tokyo.

And although she is practising new tricks, Brown - who is also a talented surfer - is not letting Olympics preparations dominate her days.

"It doesn't take up much of my life," explained Brown, who was nominated for BBC Young Sports Personality of the Year.

"I usually skate when the waves are bad. I skate most evenings. It [surfing and skating] is like ramen and ice cream - if you get too much ramen you want ice cream."

Brown does not have a coach, but skates with her dad, who she says suggests things for her to try when working on new tricks.

Despite her world-class boarding skills Brown admits she does have weaknesses - citing brushing her teeth and tidying her room as two of them.

And she would be excited to show off those skills on the world stage when skateboarding makes its Olympics debut in July.

"It's going to be really cool," she said. "You can show what skateboarding is and how creative you can be.

"A lot of people are going to watch it and I get to show that if this little girl can do it, you can do it too."

Brown will be 12 years and 12 days old when the Games open, so she would eclipse the current 'summer' record of swimmer Margery Hinton, who was 13 years and 14 days at the 1928 Olympics in Amsterdam.

Cecilia Colledge is Britain's youngest ever Olympian; she was a tender 11 years and 73 days old when she competed in the women's single skating competition at the 1932 Winter Olympics in Lake Placid.
