2015: two-year-old season On 16 July 2015 Quiet Reflection began her racing career in a five
furlong maiden race at
Hamilton Park Racecourse in which she started
2/1 second favourite in a six-runner field of colts and fillies. Ridden by the apprentice jockey Joey Haynes she went to the front approaching the final furlong and accelerated clear to win by five
lengths. The
Racing Post described the performance (achieved on
good to soft ground) as "promising". The filly was then moved up sharply in class to contest the
Group Two Lowther Stakes at
York Racecourse on 20 August when she was again partnered by Haynes. After tracking the leaders she could make no impression in the last quarter mile and finished fifth behind the
William Haggas-trained Betharah.
Graham Lee took over from Haynes when Quiet the filly was sent to Scotland for the Listed
Harry Rosebery Stakes at
Ayr Racecourse on 18 September. Easton Angel, who had finished third in the Lowther Stakes was made the odds-on favourite with Quiet Reflection the 8/1 second choice in a sixteen-runner field. Field of Vision set the pace before Quiet Reflection took the lead inside the final furlong and quickly drew away to win by four lengths. Karl Burke commented "She's a good filly. She was knocked over after 100 yards which not many people picked up on in the Lowther... Unfortunately I took her out of the
Cheveley Park after the Lowther and I wouldn't have minded having a crack at that after today." In the
Cornwallis Stakes at
Ascot Racecourse on 9 October the filly started 5/6 favourite, with Field of Vision being the best-fancied of her ten opponents. After looking outpaced in the early stages she was sent into the lead by Lee a furlong out and went clear to beat Field of Vision "readily" by two and a half lengths.
2016: three-year-old season Spring The former
National Hunt jockey
Dougie Costello took over as Quiet Reflection's regular jockey in 2016. She began her second season with a trip to France for the Group Three
Prix Sigy over 1200 metres at
Chantilly Racecourse on 10 April and started the 7/2 second favourite behind the
Jean-Claude Rouget-trained Saryshagann. Racing on heavy ground she took a clear advantage 200 metres from the finish but was hard-pressed in the closing strides before winning by a head from Jimmy Two Times. Burke commented "We have learned something there because she probably hit the front too soon. I thought we had it won easily and then when the camera angle changed and there was another 200 metres to run, I slightly had my heart in my mouth". On her next start the filly returned to Group Two class for the first time since the Lowther when she ran in the
Sandy Lane Stakes on 28 May at
Haydock Park. Gifted Master (
Pavilion Stakes) started favourite ahead of Buratino (
Coventry Stakes) and La Rioja (
Dick Poole Stakes) with Quiet Reflection on 7/1 alongside Donjuan Triumphant (
Critérium de Maisons-Laffitte). After being restrained by Costello in the early stages she took the lead a furlong out and drew clear in "impressive" style to win by three and three quarter lengths. Costello said that the filly won in a "hack canter", whilst Burke commented "She's a different filly to the one that won in France [in April]. She's physically matured since then and I knew she'd improved. It wasn't the idea to sit that far back but when I saw him cruise up on her two out, I thought he'd gone too soon. She's got a fantastic turn of foot and a high cruising speed and when you put them together, it makes something special".
Summer At
Royal Ascot on 17 June Quiet Reflection started 7/4 favourite for the second running of the Commonwealth Cup. Donjuan Triumphant and La Rioja were again in opposition, whilst the other seven runners included Log Out Island (
Carnarvon Stakes), Cheikeljack (
Prix Djebel), Washington, D.C. (
Windsor Castle Stakes), Kachy (
Molecomb Stakes), Illuminate (
Duchess of Cambridge Stakes) and Waterloo Bridge (
Norfolk Stakes). After racing just behind the leaders Quiet Reflection began a strong late run a furlong out, overtook Kachy in the last 100 yards and won by a length. After the race Burke said "Quiet Reflection is a very good filly. It was not the plan to be stuck in the middle like that and I was praying we didn’t get a rough race. When she comes through she has a great turn of foot and it has got her out of trouble again."
Autumn On 3 September Quiet Reflection returned to the scene of her Sandy Lane Stakes victory when she contested the
32Red Sprint Cup and started 7/2 favourite after Limato was withdrawn on account of the soft ground. Suedois, Kachy and Donjuam Triumphant were again in opposition, whilst the other runners were Magical Memory (
Duke of York Stakes), The Tin Man (
Hackwood Stakes), Dancing Star (
Stewards' Cup), Only Mine (
Lacken Stakes),
Gordon Lord Byron (winner of the race in 2013), Goken (
Prix du Bois), Mehronissa (
Flying Fillies' Stakes), Strath Burn (Hackwood Stakes), Jane's Memory (
Cecil Frail Stakes) and Mr Lupton. Costello positioned the favourite in mid-division before making "smooth" progress to take the lead approaching the final furlong. Quiet Reflection went clear and won by one and three quarter lengths from The Tin Man, with Suedois two and a half lengths back in third place. Costello commented "I've never ridden anything like it and probably never will again. She's push-button go. She won as she liked, she's the real deal." Burke said "I know we wanted a bit of rain but I was a bit worried when it got this soft as I thought it might play into the hands of the older horses. She's just got speed to burn. She travels well and is so relaxed. She blows when she works but when she runs she doesn't turn a hair". He later said that the filly would probably run next in the
British Champions Sprint Stakes at Ascot.
2017: four-year-old season Martin Harley rode Quiet Reflection in all three of her starts as a four-year-old. On her seasonal debut the filly came home tenth of the twelve runners behind Priceless in the
Temple Stakes at Haydock on 27 May. After a break of almost four months she returned in the Listed Renaissance Stakes over six furlongs on soft ground at
Naas Racecourse on 24 September and went off the 5/2 favourite against nine opponents. She raced in mid-division before overtaking the front-running Alphabet 150 yards from the finish and drew away to win "comfortably" by two and three quarter lengths. Burke commented "On soft ground this filly is very good and she can only sharpen up for that run. Win, lose or draw she has been an absolute star for us, and it's just great to get her back. She has a great temperament and has been a pleasure to be around." On her final appearance Quiet Reflection finished tenth in the 2017
British Champions Sprint on 21 October. It was only the third time she had finished out of the prize money. "She travelled superbly well and when Martin pulled her out everyone thought she had it in her, but she didn't quicken up like she did last year and it was one of the best sprints for many a year." After the race, she was retired, with a plan to sell her as a broodmare. In total, she won eight times and earned more than £650,000 in prize money. ==Assessment and awards==
