Does trainer form really matter? Interested in people’s views.

[pawras]

I based my answer on a reading of post #4 which is what you do with trainer form "once the market has had its say", so it'd be interesting to know what you'd do with trainer form at that point - and what you think you'd use that the market has failed to spot.

Lazy punters might point to strike rates etc, but trainer PRB and similar metrics are bound to find their way in there, even the system I've got in development uses it and over different time periods.

Unlike basic strike rates I don't think the world and his wife look at trainer PRB, even though it's far from arcane knowledge, so as I believe the market is a cumulative view of the subjective opinions of punters I don't think that will be entirely factored into the market, but also depends on how much it's assessed by those who put the biggest weight of money in the market.

Then there's PRB2 which is little bit better than PRB, then you get into private bespoke trainer metrics e.g, I have developed my own enhanced version of PRB2 which is little bit better than standard PRB2

But yeah trainer metrics based on their publicly known horse's performance are going to be factored in to the market to some degree no matter how bespoke, just not entirely imo.

I find some trainers overbet and some not so much, which feeds my view the market is not omnipotent

Personally I rarely bet purely on any trainer metrics, I generally combine them with others to get an overall view

Trainer Form & Yard Momentum (2026 Season)​

Trainer	Horse	2026 Runs	Wins	Strike Rate (SR%)	Run To Form (RTF%)
Roger Varian	Sallaal	29	8	28%	72.0%
John & Thady Gosden	Dangerman	60	17	28%	70.8%
James Owen	Asmen Warrior	282	47	17%	61.0%
Ian Williams	Parlando	229	29	13%	57.6%
David O'Meara	Dukes Command	147	17	12%	57.1%
Jack Channon	Rathgar	66	12	18%	55.3%

Track Position Overrode Physics: We flagged his massive 7.47M stride length as a negative for Epsom's sharp, downhill cambers. However, our pace map also explicitly stated: "Epsom's circuit is brutally undulating and heavily favours horses positioned prominently before they hit Tattenham Corner." Rathgar was mapped as an IP 2 (Prominent). It looks like the massive advantage of being on the front end out-weighed the clumsiness of his big stride.

2. The "Marquand Factor": We noted in his profile that Tom Marquand gave him a brilliant ride to win at Newbury last time out. Navigating a big-striding horse down the Epsom hill requires absolute top-tier racecraft to keep the horse balanced, and Marquand is one of the best in the business.

3. The Danger of Over-Penalizing Trainer Form: We downgraded Jack Channon a bit for having a 55.3% Run To Form rate compared to Varian's 72%. But 55% isn't exactly a "cold" yard, and Rathgar himself was clearly thriving.

It just goes to show that while RaceIQ physics and mathematical class ratings give us a massive edge, the human element—a brilliant jockey executing perfect tactics on the front end—can still flip the script!

Dusting myself off.
This post-race RaceIQ data is absolute gold dust. It perfectly illustrates exactly how Rathgar stole this race from the front, and why the beaten horses couldn't get to him despite having bigger engines on paper.

Here is the concrete statistical breakdown of how the 3.15 Epsom was actually won and lost:

The Tactical Masterclass (0-20 MPH Acceleration)​

The race was essentially won in the first 3 seconds out of the stalls.

• Rathgar recorded the fastest 0-20 MPH time in the field at 2.53 seconds. Tom Marquand blasted him out of the gates, immediately secured the rail, and was able to dictate the fractions ("made all").
• By contrast, the favorite Sallaal and the closer Asmen Warrior (2.92s) were much slower to get into their stride, forcing them to navigate from the rear on a track that notoriously punishes hold-up horses.

Top Speeds: The Illusion of the Fastest Horse​

This data perfectly highlights why raw top speed doesn't always win on an undulating track like Epsom if you concede a tactical advantage early.

• Sallaal possessed the biggest engine, clocking the highest Top Speed in the field at 41.42 MPH.
• Asmen Warrior clocked the second-highest at 41.13 MPH.
• Rathgar actually had the second-slowest Top Speed in the entire race at just 40.79 MPH.
• The Verdict: Sallaal was flying late, but because Rathgar secured an uncontested lead with that brilliant 2.53s start, Sallaal simply ran out of track to run him down. Tactical positioning beat raw speed.

Stride Lengths​

We originally flagged Rathgar's massive stride as a potential negative for Epsom's tight cambers, but he defied it by maintaining clean air on the front end.

• Rathgar recorded the longest average stride length at 7.05M, and the longest maximum stride at 8.16M. When a big-striding horse gets an uncontested lead and doesn't have to check its stride behind other horses, they become incredibly hard to pass.
• Sallaal operated with a slightly tighter average stride (6.99M), but he lost momentum by hanging right under pressure in the straight.

Final Debrief​

Tom Marquand rode the perfect Epsom race. He used Rathgar's early acceleration to eliminate the traffic problems associated with his massive 7.05m stride. Once he was loose on the lead, even Sallaal's blistering 41.42 MPH top speed wasn't enough to bridge the gap.

Here is the fully upgraded Master Summary Chart for the 3.15 Epsom, now integrating your Custom Ratings, Performance Ratings, and the complete Timeform Deep-Dive (TFR, Tfig, and full comments) for their last three runs (Newest to Oldest).

3.15 Epsom: Master Summary & Timeform Chart​

Horse Name	Avg Rtg	Avg PR %	TFR (L3)	Tfig (L3)	Full Timeform Comments (Last 3 Runs)
Sallaal	98.50	32.40%	87 107 108	72 104 108	Run 1: Proved to be a disappointment, failing to see his race out any better than he had at Sandown having taken a good grip in a first-time hood; handy, not settle fully, ridden 2f out, weakened over 1f out. Run 2: Hadn't been out for 2 months and, easy to back, was perhaps just in need of the run, his effort petering out late on, likely to give a good account with this under his belt; dropped out, shaken up 3f out, headway over 1f out, not quicken well inside final 1f... Run 3: The sole 3-y-o in the line up, brought a completely different profile to the table compared to the opposition and duly made light of this opening mark after 10 weeks off... loomed up over 2f out, led soon after, quickened clear, eased a shade close home and won readily.
Dukes Command	89.84	33.10%	95 98 93	74 81 69	Run 1: Again shaped better than the bare result, the exertions of being caught 3-wide eventually catching up with him; chased leaders, close up still 1f out, no extra. Run 2: Back down in trip, wasn't seen to best effect; raced wide, mid-field, hampered early in straight, switched over 1f out, headway late on, left poorly placed. Run 3: Looked a shade rusty back from 8 weeks off; steadied at the start, dropped out, came wide under 2f out, never landed a blow.
Aurel	89.08	32.00%	93 90 90	88 49 68	Run 1: Is better than he could show here, and doesn't look overburdened from a mark of 94 on this evidence; mid-division, headway when sandwiched over 2f out and lost momentum at crucial stage, rallied gradually final 1f; worth another chance. Run 2: Resumed winning ways back in calmer waters, going through the race with real zest but almost getting pegged back by another very promising one; prominent, travelled strongly, led 2f out, drew clear over 1f out, ridden final 1f, all out to hold on... Run 3: In first-time hood after 6 months off and over 2f longer trip, ran to just a similar level as on debut, seemingly outclassed up in grade... handy, took keen hold, left behind over 2f out.
Parlando	86.95	49.40%	95 86 97	90 65 74	Run 1: Back on turf, wasted no time getting back on track; raced off the pace, headway entering final 1f, stayed on. Run 2: Didn't figure this time; held up, no room and forced to switch 2f out, carried left soon after, effort flattened out. Run 3: Has had little racing at this trip but ran well, quickly bouncing back from an excusable blip on the frozen snow at St Moritz just 8 days earlier; held up, headway under pressure over 1f out, kept on.
Dangerman	82.07	51.00%	89 95 97	52 80 92	Run 1: Was below form, given another try at this trip and not really seeing it out, bred to stay but perhaps going to prove better at shorter; in touch, chased leaders 3f out, shaken up, not quicken 2f out, weakened 1f out. Run 2: Was in a much stronger race than the pair he'd won over C&D recently and acquitted himself really well, giving his all having come under pressure quite a long way out on this softer ground; chased leaders, pushed along under 4f out, hung right under 3f out, close up 2f out, no extra only late on. Run 3: Is most progressive since being fitted with blinkers and followed up from his C&D success a fortnight earlier... made all, pressed on under 3f out, drew clear approaching final 1f, eased close home.
Rathgar	77.28	57.90%	95 90 71	88 81 59	Run 1: Capitalised on the drop in grade with Marquand taking over from a 5-lb claimer, proving as good as ever tried in cheekpieces for just the second time... prominent, went with enthusiasm, led briefly under 2f out, rallied, led again final 100 yds, just held on. Run 2: Claimer ridden, shaped as if retaining all ability after 8 months off; prominent, shaken up 4f out, edged right over 1f out, no extra last ½f... Run 3: Who won this race last year, again ran poorly; prominent, weakened 2f out.
Asmen Warrior	74.88	30.50%	95 98 48	65 95 49	Run 1: Ran creditably after 6 months off but is still searching for his first handicap success with a mark that's been gradually climbing... waited with, shaken up entering straight, plugged on, took second post. Run 2: Back in cheekpieces, showed improved form stepped up 1f on his all-weather debut and surely won't be too long in notching a first win for these connections; in touch, headway from 3f out, led briefly inside final 1f, kept on. Run 3: Was well held in first-time visor returned to easier ground; tracked pace, ridden 3f out, weakened over 1f out.

Pace Map & In-Play Value Strategy ​

1. The Pace Scenario: Epsom's 1m 2½f circuit is brutally undulating and heavily favours horses positioned prominently before they hit Tattenham Corner.

• Looking at the IP profiles, Dangerman (1/2/3) and Aurel (2/3) like to go forward.
• Rathgar and Sallaal are also naturally prominent (2), though Sallaal pulled hard (p) last time.
• Parlando (IP 4) is the only dedicated closer.
• Result: There is going to be a heavy battle for early positioning. If the front four take each other on descending the hill, they could set it up for a closer, but Epsom rarely rewards horses trying to make up 10+ lengths from the back.

2. The Statistical Standout (With a Warning): Sallaal (3/1 F) He mathematically dominates this race, but he comes with serious baggage.

• The Data: His Custom Class Rating average (98.50) is top, and his Timeform Ratings (87, 107, 108) show he has group-level potential.
• The Tactics: He runs wearing a hood because he is incredibly keen. Last time out on Heavy ground, he pulled far too hard (p) and folded. If he doesn't settle today down the Epsom hill, he will not get home. He is the most talented horse in the race, but a risky betting proposition at 3/1.

3. The Solid Tactical Value: Rathgar (4/1) If Sallaal boils over, Rathgar is perfectly positioned to capitalize.

• The IP Profile: Last time out at Newbury, he earned the k (went with enthusiasm) flag while tracking the leaders. He was given a brilliant ride by Tom Marquand (who is on board again today). Because he is tactically versatile (can lead or sit handy), Marquand can avoid the early speed duel, save ground on the rail, and pounce late. He is a very safe each-way play.

4. The In-Play Lay Target: Dukes Command (8/1)

• The IP Profile: He has a terrible habit of dropping out the back and starting slowly (s). Epsom is the worst track in the country for a horse that misses the break.
• The Data: His PRB² average is an abysmal 0.19. He consistently fails to beat horses home. He is an excellent Lay target, as his odds will likely balloon in-running as soon as he drops to the rear.

Progressive Horses Analysis ​

There is one extremely interesting young horse in this field who was thrown into the deep end too early.

The "Forgive Run" Improver: AUREL

• Class Rating Trajectory: 34.96 → 99.00 → (81.28 - Excused)
• Timeform Rating (TFR) Trajectory: 90 → 90 → (93)
• Timeform Speed (Tfig) Trajectory: 68 → 49 → (88)
• Analysis: Ignore his dismal 34.96 run; as Timeform noted, he was "outclassed up in grade" into a Listed race at Newmarket. He bounced back to record a brilliant 99.00 Class Rating win at Leicester. Last time out, Ralph Beckett threw him into a brutally competitive 15-runner £110k handicap at Royal Ascot. He got "sandwiched over 2f out and lost momentum at a crucial stage," yet still ran a 93 TFR. Dropping back down into standard Class 2 company today, he is a massive sleeper at 13/2 if he navigates the Epsom cambers successfully.

Someone's just pointed out on another forum that Tim Easterby had 6 winners from 8 runners yesterday .

Whilst Royal Ascot has been on, his figures read;

9-18-36 for 25% win, 50% place and an A/E of 1.38

I always have a mental picture in my mind of hot and cold trainers before placing a bet. Also, when trainers are usually at their best e.g. at the start of the season Oct/Nov. Twiston Daives usually has his horses fitter than a few others.

some have very seasonal highs and lows and others largely level regardless

 

[gerry]

I would say without doubt it matters like every thing else in form guides everything that's positive is better than negative but what happens is a lot bet it blindly then think does it work where i would say it works most if a horse is your form horse but not run for month and trainer last month been quiet then there must be doubts.

 

[markfinn]

There must be some politicians at large - a thousand words to answer a simple question -
Yes of course stable form counts how else can you measure a stables fitness ( health wise) - is it the be all and end all - no - but you need to consider stable size ( number of horses , not acres) - Look at last 28 days / have they had any runners ? If so Race sizes ( number of runners ) Have any placed - Yes happy - No investigate or drop

 

[mlmrob]

Yes, and if their 14 day and 7 day strike rates are higher than their 1 and 2 year strike rates then the stable could well be in form. I set a bar of 5% above.

sam England trundling along nicely atm R=Runners S = Strike, DSW days since last winner, RSWIN, Runners since last winner, 2YFAV, 2yr strike rate with favs, 2YHCST, 2yr handicap strike rate.

Haggas is always in form - if drops then you know it’s a problem - wonder what a stable proximity map would show

 

[gerry]

the stats on racing post for trainers are well of as they only go by how the horse should run compared to race i was on AI other night and AI said a certain trainer is absolutely flying at 85 percent and i said if flying is no winners in last 24 runners in last 14 days is flying then god help us.
