Decoding the Caulfield Cup: Historical Winner Profile, Lead-Up Pathways & 2026 Race Blueprint
The Caulfield Cup is one of Australia’s most prestigious and historic feature races, traditionally known as one of the four Grand Slam events held annually alongside the Melbourne Cup (3200m), the Cox Plate (2040m) and the Golden Slipper (1200m). In recent times, The Everest (1200m), also running tomorrow at Randwick, may be considered as a 5th Major by many.
Across the last nine editions of the Group 1 Caulfield Cup (2400m) (2017 to 2025, comprising 161 total starters), historical data reveals a remarkably strict, non-negotiable statistical blueprint. Unlike the Randwick mile (Epsom Handicap) where bottom-weight 50.0kg 4YOs dominate, the Caulfield Cup is a high-pressure 2400m stamina and class examination where seasoned 5YO to 7YO Group performers dropping in weight off a close lead-up finish hold an undisputed 100% monopoly on the honour roll.
The Core Finding: Class, Stamina & Weight Relief
Every single winner since 2017 was between 5 and 7 years of age, finished 1st to 6th in their lead-up run beaten no more than 2.7 lengths, and dropped at least 0.5kg in weight into the race. Applying these historical gates eliminates 70% of historical runners while capturing 100% of winners.
Historical Winners Honour Roll (2017–2025)
Examining the key profiles of the last nine winners highlights the tight parameters that produce Caulfield Cup champions:
| Year | Winner | Age/Sex | Weight (Change) | Barrier | Lead-Up Race | Lead-Up Result | Base / Last Start Rank | SP |
|---|---|---|---|---|---|---|---|---|
| 2025 | Half Yours (#15) | 5g | 52.5kg (-3.5kg) | 2 | G1 Turnbull Stakes (Flem 2000m) | 4th (2.7L) | #7 / #7 | $2.60F |
| 2024 | Duke De Sessa (#10) | 6g | 52.0kg (-3.0kg) | 5 | G1 Turnbull Stakes (Flem 2000m) | 4th (2.1L) | #10 / #8 | $10.00 |
| 2023 | Without A Fight (#2) | 7g | 55.5kg (-3.5kg) | 7 | G1 Underwood Stakes (Caul 1800m) | 6th (2.2L) | #5 / #5 | $8.50 |
| 2022 | Durston (#19) | 7g | 51.5kg (-1.5kg) | 6 | G1 The Metropolitan (Rand 2400m) | 6th (1.3L) | #10 / #10 | $17.00 |
| 2021 | Incentivise (#2) | 5g | 55.5kg (-2.0kg) | 18 | G1 Turnbull Stakes (Flem 2000m) | 1st (-0.5L) | #3 / #3 | $2.30F |
| 2020 | Verry Elleegant (#7) | 5m | 55.0kg (-0.5kg) | 8 | G1 Turnbull Stakes (Flem 2000m) | 1st (-0.1L) | #2 / #6 | $5.40F |
| 2019 | Mer De Glace (#3) | 5h | 55.5kg (-2.0kg) | 17 | G3 Kokura Kinen (Japan 2000m) | 1st (-0.3L) | #1 / #1 | $7.90 |
| 2018 | Best Solution (#1) | 5h | 57.5kg (-2.5kg) | 15 | G1 Grosser Preis von Baden (2400m) | 1st (-0.3L) | #4 / #3 | $12.70 |
| 2017 | Boom Time (#13) | 6h | 52.0kg (-4.5kg) | 3 | G2 Herbert Power Stakes (Caul 2400m) | 4th (2.4L) | #10 / #5 | $46.00 |

Statistical Proof Across All 161 Historical Starters:
- Lead-Up Beaten Margin (Last Start Margin ≤ 2.7L & Last Finishing Position ≤ 6):
- Won Lead-Up (≤ 0.0L): 28 starters: 4 Wins (14.3% Win, 28.6% Place) (Incentivise, Verry Elleegant, Mer De Glace, Best Solution).
- Beaten 0.1L to 2.7L (2nd to 6th): 63 starters: 5 Wins (7.9% Win, 22.2% Place) (Half Yours 2.7L, Duke De Sessa 2.1L, Without A Fight 2.2L, Durston 1.3L, Boom Time 2.4L).
- Beaten > 2.7L or Finished 7th+: 70 starters: 0 Wins (0.0% Win). Historically, horses beaten more than 2.7 lengths in their final lead-up have never recovered to win the Caulfield Cup in modern times.
- Base & Last Start Rating Ranks (Base Rating Rank ≤ 10 & Last Start Rating Rank ≤ 10):
- Top 5 Base Rating Rank: 45 starters: 5 Wins (11.1% Win, 33.3% Place).
- Rank 6 to 10 Base Rating Rank: 45 starters: 4 Wins (8.9% Win, 17.8% Place).
- Rank 11+ Base Rating Rank or Last Start Rating Rank: 71 starters: 0 Wins (0.0% Win, 5.6% Place).
- Weight Bracket (51.5kg to 57.5kg) & Weight Relief (Weight Change ≤ -0.5kg):
Two distinct winning clusters exist: Progressive / Down-in-Weights Group Horses (51.5kg to 53.0kg) (4 wins, including Half Yours, Duke De Sessa, Durston, Boom Time) and Elite WFA / International Class Performers (55.0kg to 55.5kg) (4 wins, including Without A Fight, Incentivise, Verry Elleegant, Mer De Glace), plus Best Solution at 57.5kg.
The Minimum-Weight Trap (≤ 51.0kg): 21 starters: 0 Wins, 0 Places (0.0% strike rate). Unlike 1600m handicaps, true bottom-weight runners lack the class base to withstand 2400m pressure at Group 1 level.
Weight Relief: 9/9 winners dropped between -0.5kg and -4.5kg (mean -2.56kg). Horses carrying the same or more weight are 0/17.
- Age Maturity (5YO to 7YO):
5YOs represent the sweet spot with 5 wins and 15 places from 50 starters (10.0% Win, 30.0% Place). 6YOs and 7YOs make up the remaining 4 wins. Conversely, 4YOs are 0 wins from 30 starters (only Vow And Declare placed 2nd in 2019).
Lead-Up Pathways & The 2026 Heavy 8 Turnbull Stakes Nuance
Traditional Lead-Up Hierarchy (2017–2025)
- G1 Turnbull Stakes (Flemington 2000m, 14 days prior): The Premier Source
Has produced 4 of the last 9 winners and 12 of 27 placegetters (Half Yours 2025, Duke De Sessa 2024, Incentivise 2021, Verry Elleegant 2020). Winners either win the Turnbull at WFA/SWP or finish 4th within 2.1L to 2.7L carrying 55kg to 56kg before dropping 3.0kg to 3.5kg into the Cup. - Direct International Raid (48 to 77 days prior, 2000m to 2671m Group Win)
Produced 2 of the last 9 winners: Mer De Glace (2019, won G3 Kokura Kinen 76 days prior, ranked #1 on Base Rating and #1 on Last Start Rating) and Best Solution (2018, won G1 Grosser Preis von Baden 48 days prior). Both were high-calibre European or Japanese Group stayers. - Caulfield 1800m to 2400m Lead-Ups (Underwood / Might And Power / JRA Cup / Herbert Power)
Produced 2 winners (Without A Fight 2023, Boom Time 2017) and 9 placegetters. - G1 The Metropolitan (Randwick 2400m, 14 days prior)
Produced Durston (2022) and Land Legend (3rd in 2024).
Critical 2026 Track Condition Overlay: The Heavy 8 Turnbull Distortion
In 2026, ten Caulfield Cup entrants contested the G1 Turnbull Stakes 14 days ago at Flemington, which was run on a testing Heavy 8 surface:
- #2 Cosmic Crusader relished the testing going to win by 1.8 lengths with an impressive performance, backing up his strong effort when 2nd on a Good 3 two starts back.
- However, behind him, the margins blew out abnormally due to the heavy track conditions (5th beaten 6.5L, 6th beaten 9.3L, 10th beaten 11.8L, 11th beaten 18.8L).
- Because the 2026 Caulfield Cup is scheduled on a Good 4 track, we must separate runners who are genuinely out of form from elite dry-trackers who simply failed to handle the Heavy 8 conditions after posting elite winning or placing figures on a Good 3 two starts back: most notably #16 Zahrann (ranked #1 on Peak Rating) and #12 Saint George.

Deep-Dive Contender Breakdown
Wine Dark Sea (#10)
Harry Charlton (Trainer) | Damian Lane (Jockey) | 54.5kg (-6.5kg drop) | Barrier 19 (jumps from ~15)
The 2019 Mer De Glace Clone: In 2019, Damian Lane steered 5YO Japanese raider Mer De Glace (55.5kg, Barrier 17, 76 days fresh off an overseas Group win, ranked #1 on Base Rating and #1 on Last Start Rating) to a famous sweeping victory. Tomorrow, Lane jumps aboard 5YO UK stayer Wine Dark Sea (54.5kg, Barrier 19, 63 days fresh off winning the G3 Geoffrey Freer Stakes over 2671m at Newbury by 1.5L, ranked #1 on Base Rating and #1 on Last Start Rating).
Massive Weight Relief: Drops 6.5kg from the 61.0kg he carried to victory at Newbury, and brings proven fast-ground (Firm/Good) 2400m to 2671m stamina with 3 wins over staying trips.
Model Validation: Ranked #2 overall by our ML Model (9.8% Win Probability, $10.25 fair). Satisfies all 5 Historical Gates with a near-perfect 96/100 profile score.
Cosmic Crusader (#2)
Andrea Leek (Trainer) | William Pike (Jockey) | 56.0kg (-2.0kg drop) | Barrier 17
Dominant Turnbull Lead-Up: Emulates Incentivise (2021) and Verry Elleegant (2020) by arriving 14 days after winning the G1 Turnbull Stakes (2000m at Flemington), putting away the field with authority by 1.8 lengths.
Dual-Surface Versatility: Prior to his Heavy 8 Turnbull triumph, he posted a strong performance on a Good 3 (2nd beaten 1.8L), ranking #2 on Base Rating and #2 on Last Start Rating.
The Only Question Mark: Untested at 2400m (0 starts at the distance) and drawn Barrier 17 with 56.0kg, which demands a measured ride from William Pike early. Nevertheless, he sits as the #1 selection on our ML Model (14.5% Win Probability) and passes 5/5 Historical Gates (90/100).
Zahrann (#16) & Saint George (#12)
Ciaron Maher stable | Lightweight Group performers with elite dry-track credentials
#16 Zahrann (5YO Horse | 53.0kg [-3.5kg] | Barrier 4 | Ethan Brown | ML #3 at 8.9%)
Completely forgive his 11th (beaten 18.8L) in the mud of the Turnbull Stakes, which artificially skews his raw last-start finishing position. Two starts back on a Good 3, he won by 1.0L.
Crucially, Zahrann holds the #1 Peak Rating in the entire field. He is a proven 2414m winner and replicates the Ciaron Maher lightweight blueprint (Duke De Sessa won in 2024 carrying 52.0kg from Barrier 5; Zahrann carries 53.0kg from Barrier 4).
#12 Saint George (7YO Gelding | 53.5kg [-1.5kg] | Barrier 2 | Craig Williams | ML #5 at 7.6%)
Equally excusable on the Heavy 8 Turnbull (10th, 11.8L) after running 2nd (1.0L) on Good 3 two back and winning three back. Ranks #4 on Peak Rating with the luxury of an uncontested economical run from Barrier 2.
Treasurethe Moment (#3) & Royal Supremacy (#9)
#3 Treasurethe Moment: $26.00 (Model Fair: $12.12 | ML #4 at 8.3%)
+114% Market Overlay: 5YO mare dropping 1.5kg from WFA in the G1 Might And Power Stakes (2000m at Caulfield 7 days ago, where she finished 5th beaten 4.5L after running 2nd beaten 1.5L two starts back). Already a proven Group 1 2400m/2500m winner, drawn perfectly in Barrier 5at 55.5kg (matching Verry Elleegant's 55.0kg 5YO mare blueprint). At $26.00 vs $12.12 fair odds, she represents the clear top mathematical value overlay in the race.
#9 Royal Supremacy: $14.00 (5/5 Historical Gates, 88/100 Profile Score)
The only local starter drawn inside Barrier 10 who passes all 5/5 historical gates. 6YO gelding trained by Ciaron Maher who won the G3 JRA Cup (2000m at Caulfield) last start by 0.8L, is a proven 2400m winner, and drops -5.5kg from 60.0kg down to 54.5kg from Barrier 8 with tactical pace.
If two scratchings occur prior to final scratching time, G1 Metropolitan (2400m) winner Juja Kibo (52.0kg, dropping -4.5kg) boasts the highest historical profile score (97/100) in the book. If he gains a start, he immediately enters the main betting ticket.
Final Summary
