Kent Farrington has a habit of finding them early. Greya, Gazelle, Toulayna, Creedance and Myla were all rated among the best of their generation at nine. Most of them went on to win the biggest Grand Prix classes in the sport.

Descartes SR is the latest. A podium finish in the MLSJ Grand Prix of Greenwich on 27 September made him the highest-rated nine-year-old in the world. The question now is how far he can go.

 

Top of his age group

Nobody in his generation is closer than Mckayla Langmeier's Riesling van de Gaathoeve, 10 points behind. The two Americans have a clear gap on a strong German group led by Philipp Weishaupt and Lady Concern du Rezidal.

How Elo works: The EquiRatings Elo rating ranks horses on who they beat, and who beats them, every time they compete in a CSI4* or CSI5* round at 1.50m or higher.
 

Five-star from the first start

Descartes SR did not need long to find his level. His first five-star 1.60m class was the MLSJ Grand Prix at Lexington in April. He jumped clear and won it. A week later he was on the podium again in Monterrey.

Summer in Europe was a sterner test. He jumped clear in the first round of the Falsterbo Nations Cup, had a fence down in the second and helped his team to third. Two weeks later he retired in the King George V Gold Cup at Hickstead.

Back in North America he picked up where he left off, second at Rockwood in early September and second again at Greenwich three weeks later.

Every five-star Grand Prix he has finished this year, he has finished on the podium.

Gazelle is the reminder that the rating at nine only tells part of the story. She never climbed as high on the Elo scale as Greya or Toulayna. She still won more five-star Grand Prix classes than any of them, the Rolex Grand Prix of Aachen in 2019 among them.

Greya and Toulayna came through together as nine-year-olds in 2023. Three years on, both are rated higher than ever, and have a World Cup Final title to show for it.

 

The Benchmark

For Descartes SR, the horse to measure himself against is in his own stable. Greya was rated just above him at nine. She has kept climbing ever since and is now the highest-rated of Farrington's six, a Rolex Grand Prix winner in Geneva with a dozen five-star wins behind her.

If he follows Greya's path, Descartes SR would land alongside Toulayna's best.
Greya has gained 67 points since she was nine. The same climb would take Descartes SR to 783.

Gazelle and Greya turned ratings of 716 and 720 into 26 five-star 1.60m wins between them. Descartes SR has one. He is still only nine.
