From tennis whites to dirt bikes: Emma Raducanu muddy at motocross

She intimidates opponents with her 100mph serve – now Emma Raducanu has fulfilled her need for speed in a return to motocross.

The tennis star got back on a bike at Canada Heights track in Kent for a Nike advert. Miss Raducanu, 19, who has a £100,000-a-year sponsorship deal with the brand, wore a black top, trousers and helmet, and also filmed herself using a selfie stick. 

On winning the US Open, she revealed: 'I was racing go-karts for a year or two when I was younger and then I transitioned into motocross... but I couldn't carry on with it as my tennis career progressed.'

She previously posted childhood photos of herself riding a Kawasaki, including a close-up of her face in a green helmet.

She wrote: 'tbt the good days riding my baby kawa #motocross.'

Miss Raducanu enjoyed a hodgepodge of sports as a child, encouraged by her father to try horse riding, swimming, basketball, golf and skiing.

Her victory at the US Open saw her named BBC Sports Personality of the Year 2021 and sparked a flurry of endorsement deals.

She was dripping in £40,000 worth of Tiffany jewellery when she stormed into the second round of the Australian Open last month having signed an estimated £2 million deal with the luxury jeweller in September.

She is also a global brand ambassador for British Airways, and Evian and recently signed a lucrative deal with Dior.

She could now be worth £6million according to experts.

Last week she appeared to poke fun at her critics in a 20 second advert for Nike which showed her hitting balls as the words 'distracted', 'perfect', 'fluke' and 'one-hit wonder' flashed up on screen.
