This we know: Success at the top levels of show jumping sport is the culmination of years of careful development. But what patterns exist among the sport’s best equine athletes?

As the 2022 show calendar nears its end, Priview is diving deeper into the numbers behind the season’s top performers. For this case study, we sought to answer the following questions:

  • Does success as a young horse correlate with success at the top level? How about longevity?
  • Does the number of starts a horse makes as a young horse influence its performance in its prime years?
  • Is there a prime age to step up to top level sport?

We selected 7 of the sport’s most accomplished equine athletes and broke their careers down into three segments—Young (ages 4-9); Prime (10-14); and Mature Horse (15+) to examine the numbers.

The Data

This first graph illustrates these horses’ average faults and average finish position in the different age segments. According to Prixview data, as these top horses’ aged, their finish positions improved, indicating a careful development unfocused on winning at a young age.

Faults, however increased, an illustration of the increased level of difficulty as well as rule changes in how faults are calculated over the course of the last year.

James Kann Cruz performed best of this group as a young horse in international competition, jumping his first FEI classes at age 6. Cayman Jolly Jumper started in FEI classes youngest, beginning at age 4 in France. The reigning individual Olympic gold medalist, Explosion boasts the best numbers in his prime. Interestingly, HH Azur—who just won the Rolex Grand Prix of Geneva at age 16—made among the fewest starts of this group as a young horse, perhaps a factor of her longevity.

What other trends were evident? We found that among this group, there was no relationship between the number of competitions the horse competed in when they were younger and their average positions and faults at the five-star level (Note the flat trend lines).

When is the prime age to step a horse up to 1.60m? Each one of these horses made the move in their 9-year-old year. James Kann Cruz has undoubtedly found success at the level earliest of this group (Remarkably, he was born latest in the year of this group as well, with a July birthdate), while the majority of the other top performers fall within the “prime” age segment.
