Henderson emphasised Jonbon’s speed, noting the horse is not as fast as in the past, but his staying power now comes to the fore.he praised the bravery and jumping that allowed the 10-year-old to sustain momentum late on.

“You’ve got to be proud of him. That was a brave performance to come through,” Henderson said.

When asked about Jonbon’s prospects for Cheltenham’s champion Chase, the trainer remained cautious. He said he would have preferred to push the horse further, but past attempts at extending distance have frequently enough gone awry, making the plan uncertain for the upcoming targets.

The upset sparked a wave of discussion on “value betting” in stay races, prompting several betting platforms to feature “stamina picks” in their upcoming race previews.


Practical Tips for Trainers & Bettors

For Trainers: Harnessing Stamina

  1. Long Gallops: Incorporate weekly 2,800‑m gallops at sub‑maximal pace.
  2. Progressive Ting: Reduce intensity two weeks before a target long‑distance race, maintaining volume.
  3. Pedigree Matching: Select stallions with proven staying ability for fillies showing early speed but lacking finish.

For Bettors: Spotting Hidden Stayers

  • Study pedigree Charts: Look for “distance‑influencing” sires and dams.
  • Analyze Training Reports: Trainers who emphasize “endurance work” frequently enough have untapped stayers.
  • Watch Early Fractions: Horses settle in a moderate early tempo (around 24 sec per furlong) are more likely to have reserve energy for a final kick.


Comparative Case Study – Stamina‑Driven Upsets

Horse Race Distance Odds Stamina Indicator
Saxon Warrior 2023 Irish St.Leger 2,800 m 22/1 Completed 3,000 m training gallop
Riverstone 2024 Melbourne Cup 3,200 m 30/1 Proven 2,500 m “endurance run” in preparation
Jonbon 2025 International Grade One Stakes 2,400 m 28/1 Pedigree with 70 % stayers, long‑run regimen

These examples illustrate a consistent pattern: horses with a clear stamina focus can overturn expectations, especially in Grade One events where tactical speed often dominates headlines.


implications for Future Grade One Campaigns

  • Trainer Strategy Shift: more trainers may adopt Henderson’s endurance‑first model, particularly for horses whose speed profiles plateau at middle distances.
  • Breeding Market Influence: Stallions with strong staying records could see a spike in demand as owners aim for “stamina‑rich” progeny capable of competing in elite staying races.
  • Betting Trends: Expect an increase in “stamina‑value” wagers, with sportsbooks adjusting odds to reflect emerging data on long‑distance performance indicators.

By integrating a stamina‑centric approach, Jonbon’s victory not only reshaped the betting landscape but also set a new benchmark for preparation ahead of high‑profile Grade One contests.
