The 7lb Question: can Constitution River’s age allowance topple Ombudsman?
The Juddmonte’s weight-for-age terms hand the three-year-old 7lb, but a decade of results suggests that is no guarantee
How weight-for-age works in the Juddmonte
The Juddmonte International is run under weight-for-age, the sliding scale designed to let younger, still-developing horses meet their elders on fairer terms. Here the three-year-olds carry 9st 1lb, and the four-year-olds and upwards carry 9st 8lb. That’s a difference of exactly 7lb, with fillies and mares receiving a further 3lb.
In other words, a three-year-old colt lines up 7lb better off than the older horses. It is worth clearing up one common slip: some previews quote an 8lb allowance, but the official weights make the gap 7lb, and that is the number that matters.
The 2026 match-up: Ombudsman concedes 7lb
This year the scale frames the race of the season. Ombudsman, a five-year-old, shoulders 9st 8lb and hands 7lb to the three-year-old Constitution River on 9st 1lb. The question the whole contest turns on is simple: is that 7lb enough to bring the joint-highest-rated horse in the world back to a brilliant younger rival, especially with the draw putting them at opposite ends of the stalls?
What a decade of data tells us
The International, first run in 1972, has never belonged to one age group. Across the last ten runnings the winners split almost evenly, four four-year-olds, three five-year-olds and three three-year-olds, so the younger brigade has neither dominated nor been shut out.
The roll of honour also shows that the very best three-year-olds can and do defy their elders. Sea The Stars in 2009 and City Of Troy in 2024 both took the prize against older horses.
| Year | Winner | Age | Weight-for-age |
|---|---|---|---|
| 2025 | Ombudsman | 4yo | Top weight (no allowance) |
| 2024 | City Of Troy | 3yo | Received 7lb |
| 2023 | Mostahdaf | 5yo | Top weight (no allowance) |
| 2022 | Baaeed | 4yo | Top weight (no allowance) |
| 2021 | Mishriff | 4yo | Top weight (no allowance) |
| 2020 | Ghaiyyath | 5yo | Top weight (no allowance) |
| 2019 | Japan | 3yo | Received 7lb |
| 2018 | Roaring Lion | 3yo | Received 7lb |
| 2017 | Ulysses | 4yo | Top weight (no allowance) |
| 2016 | Postponed | 5yo | Top weight (no allowance) |
Last ten runnings (2016–2025): only three winners were three-year-olds taking the 7lb allowance. Four were four-year-olds and three were five-year-olds, all carrying top weight.
When the allowance wasn’t enough
The most relevant data point is also the most recent. Twelve months ago Ombudsman, then a four-year-old, conceded the same 7lb to the three-year-old Delacroix. He still won going away, by three and a half lengths on good to firm ground.That result is the strongest argument for the older horse: when the younger challenger is good but not exceptional, 7lb has not bridged the gap.
So, is 7lb enough in late August?
By this stage of the season the leading three-year-olds have usually done much of their growing up. That can make the weight-for-age concession look generous rather than decisive. Constitution River is no ordinary three-year-old, and the terms are in his favour.
But history is a reminder here, and last year’s renewal in particular. Against a truly top-class older horse, the scale is an aid, not a trump card. On the numbers, 7lb makes this a live question rather than a settled one.
The essentials
- WFA terms: 3yo 9-1; 4yo+ 9-8; fillies/mares −3lb → 7lb to three-year-olds
- 2026: Ombudsman (5yo, 9-8) gives 7lb to Constitution River (3yo, 9-1)
- Most recent test: 2025 – Ombudsman beat 3yo Delacroix by 3 1/2l on the same 7lb; allowance not enough
- Last 10 winners by age: four 4yo; three 5yo; three 3yo
- Notable 3yo winners: Sea The Stars (2009), City Of Troy (2024)
