Mawj is a small bay filly with a white star and a white coronet on her left forefoot bred in Ireland by her owner, Sheikh Mohammed's Godolphin organisation. Her name is Arabic for "wave". She was sent into training with Saeed bin Suroor who is based in Newmarket in summer but moves to Godolphin's base in Dubai in winter.
In 2022 Mawj was campaigned exclusively over six furlongs and was ridden in all of her races by Ray Dawson. The filly made her debut in a novice race (for horses with no more than two previous wins) on good to firm ground at Newmarket Racecourse on 14 May and started the 12/1 sixth choice in a twelve-runner field. After being restrained by Dawson in the early stages she moved up to take the lead a furlong from the finish and drew away from her rivals to win by four and a half lengths in "impressive" style.[5] Mawj was immediately stepped up in class and started favourite for the Group 3Albany Stakes at Royal Ascot in which she finished second of the sixteen runners behind the Aidan O'Brien-trained Meditate a filly who went on to win the Breeders' Cup Juvenile Fillies Turf.
The filly was then moved up to Group 2 class for the Duchess of Cambridge Stakes at Newmarket on 8 July and started the 4/1 third favourite in a field of six fillies. She led from the start and despite hanging to the left in the closing stages she "kept on well" to prevail be half a length from the favourite Lezoo.[6] The racecourse stewards held an inquiry into possible interference but the result remained unaltered. Saeed bin Suroor commented "She's a tiny filly, but she's always had class. When she won at Newmarket first time she did so after just one piece of work in her life... We'll keep options open, but all trainers think when they have a small filly they need to make the most of it. She may grow, I hope she does and sometimes fillies change as three-year-olds, but the Cheveley Park will be a nice race for her and then we'll take her to Dubai."[7]
In August Mawj contested the Group 2 Lowther Stakes at York Racecourse and came home fourth of the thirteen runners behind Swingalong. Queen Me and Matilda Picotte. For her final run of the season the filly was stepped up to Group 1 level for the Cheveley Park Stakes at Newmarket on 24 September. Starting at odds of 10/1 she stayed on well in the closing stages to take third place behind Lezoo and Meditate, beaten one and a half lengths behind the winner.[8]
In the official two-year-old ratings for 2022, Mawj was rated the equal ninth-best juvenile filly of the season in Europe, eight pounds behind the Moyglare Stud Stakes winner Tahiyra.[9]
2023: three-year-old season
For the winter on 2022/3 Mawj was sent to Godolphin's training base in Dubai. She made her seasonal debut in the Jumeirah Fillies Classic over 1400 metres at Meydan Racecourse on 27 January when she was ridden by Pat Cosgrave and started second favourite behind another Godolphin runner Dream of Love. After tracking the leaders, Mawj went to the front 200 metres from the finish and held off a late challenge from Dream of Love to win by a short head.[10] Four weeks later, ridden by Danny Tudhope, Mawj started joint favourite for the Jumeirah Fillies Guineas over 1600 metres at the same track. She took the lead soon after the start and drew away from her opponents in the straight to win in "impressive" style by eight and a half lengths from the Prestige Stakes winner Fairy Cross.[11] After the race Saeed bin Suroor commented "Mawj has plenty of speed, as she showed over six furlongs... Now we will look at the English Guineas or the French Guineas – it will depend on what the boss decides... As a two-year-old, Mawj was tiny and skinny. You would not think she is a lot but every time she worked in the morning she showed some class... She grew a little when she arrived in Dubai and the warm weather helped her. She looks a nice filly for the future".[12]
On her return to Europe, Mawj contested the 210th edition of the 1000 Guineas over the Rowley Mile at Newmarket on 7 May Cachet, when she was partnered by Oisin Murphy and started the 9/1 fifth choice in the betting behind Tahiyra, Meditate, Dream of Love and Remarquee (Fred Darling Stakes). The other fifteen runners included Lezoo, Fairy Cross, Matilda Picotte, Queen Me and Mammas Girl (Nell Gwyn Stakes). Racing down the centre of the wide Newmarket straight, Mawj started well and was among the leaders from the start. In the last furlong the race devolved into a two horse race between Mawj and Tahiyra, and Mawj got the better of a sustained struggle to win by half a length with the pair finishing more than seven lengths clear of the rest.[13] After the race, Murphy, who had recently returned from a 14-month ban from riding commented "It is lovely to see a Classic like that when they go clear and show their class. I was watching Mawj's replays again this morning and was thinking did she really win by eight and a half lengths last time in Meydan, and why did she win so easily? She is clearly just exceptional".[14]
