Girl, 15, bags second Crossfit world title

Keira has won the under-16s female title two years in a row

A teenager from the UK has been crowned a Crossfit world champion for the second year in a row.

Keira, 15, from Stoke-on-Trent, won the under 16s category at the contest in Ohio, USA, and said it had taken a little time to realise what she had achieved.

"It's sunk in a bit more now, because afterwards you don't really comprehend what you've done," she said.

Keira is trained by her dad Joel at their gym in Hanley, and her brother has also won the British and a world title previously. Crossfit is a fitness programme which uses high intensity movements such as powerlifting.

Motivation could sometimes be a challenge, Keira said, particularly with things like school and homework to manage on top of her training.

Crossfit is growing in popularity in the UK, but already has a strong following in America.

Joel said he was on a mission to increase the number of people taking part in the sport here – and to help his own kids become the best in the world.

Keira's success had attracted more people into the sport – and this year Joel said he had trained three athletes, including his daughter, to get to the international competition.

"To have three UK athletes from my gym go and take part against the best in world is massive," he said.

"It's really tough," he added. "The training involved is just a different level."

Keira trains for about four hours per day

Keira started taking part when she was seven, initially as a way to improve her fitness for football games.

She went along to the gym once or twice per week, then as she found she enjoyed it more she built it up.

She is now in the gym daily for about four hours per day, she told BBC Radio Stoke.

Mum Lisa added it was "amazing" watching Keira go out and do what she loves.

"Watching her out there on the competition floor makes me proud, but I think watching how hard she works leading up to it makes me prouder."
