Turner becomes the first female rider in the UK to reach the four-figure milestone.

The 40-year-old has been inching closer to the landmark win over the last few months and secured her 999th success at Newmarket on November 4.

After 15 failed attempts, she finally made it across the line in first place again as the David Simcock-trained Tradesman won the Illuminate Christmas Ball Handicap over two miles to complete a hat-trick of wins at Chelmsford.

Turner gave Tradesman, who was sent off the 9/4 favourite, a supremely confident ride as she held him up at the rear of the field with A Poet's Secret setting the pace.

After leaving the back straight, she gradually weaved her way through her rivals and, after finding a gap, Tradesman stormed clear in the closing stages to win comfortably from De Vega's Warrior.

Turner told Racing TV: "I did drag it out a little bit and made a little bit of a mountain out of a molehill, but I got there eventually. It's good.

"It's taken me plenty of time. It's nice to see the girls behind me that are up and coming - Hollie (Doyle), Saffie (Osborne), Nicola (Currie), Josephine (Gordon) - they are all riding so well every day and although it's taken me 23 years to do it, it will probably take them half the time. It's nice to see the progression from when I started until now, it's great.

"It feels like a bit of a relief now I've done it. I kind of put pressure on myself but I'm just chuffed now."

Turner rode her first winner back in 2000 and became joint-champion apprentice in 2005 before making history as the first female jockey to ride 100 winners in a year in 2008.

She has also enjoyed success at the highest level, winning the 2011 Group One July Cup with Dream Ahead, whose owner Khalifa Dasmal also owns Tradesman.

Dream Ahead's triumph was quickly followed by another elite-level success on board Margot Did in the Nunthorpe Stakes at York just over a month later.

Speaking of her best racing memory so far and her biggest supporters, Turner added: "David Simcock, who gave me my first Group One winner and has been a supporter of mine since day one and continues to do so.

"It was particularly nice to have a Group One winner for Michael Bell on Margot Did in the Nunthorpe, he helped get me going as an apprentice and got the ball rolling. That was one of the hardest things to do at that time because we girls weren't that fashionable. He's really put his neck on the line, as has David, to get me here."

The Professional Jockeys Association paid tribute to Turner, with interim chief executive Dale Gibson saying: "It's rare for jockeys to ride 1,000 winners, but Hayley Turner OBE has become the first female rider in Britain to do so.

"Her career to date has been full of superlatives; Hayley was the first female jockey to ride 100 winners in a season, she was also champion apprentice jockey as well as winning some of the UK and world's most prestigious races, including four Royal Ascot winners to date.

"Hayley is one of a growing number of outstanding female jockeys in Britain who compete against men at the highest levels of the sport and across the globe. The Professional Jockeys Association, which champions all jockeys' interests, believes Hayley's achievements will encourage many more women to participate in the sport, with the expectation that more than a fifth of all jockeys in the UK will be women by 2030.

"Congratulations Hayley - a truly fantastic achievement."
