Season map
The three bars are Impact Values for low, middle and high stalls at that course and distance band — a group's win rate against the average for everyone at the same course and trip. 1.00 is neutral; 1.30 means that third wins 30% more often than it should; 0.70, 30% less. Source: racingalpha.co.uk, every GB and Irish flat race with 6+ runners, June 2023 to June 2026. Stalls are ranked among the horses that actually ran, so withdrawals don't distort the thirds.
The verdict is driven by the spread between the best and worst thirds — because at entry stage you don't know your stall, so what matters is how much of a lottery you're buying into. Under 0.25 reads draw neutral; 0.25–0.45 draw matters; over 0.45 draw lottery.
Thirds within 0.08 of the best are treated as level with it. Bellewstown 5–6f (1.08 / 0.77 / 1.12) therefore reads "middle poor", not "high favoured" — low and high are effectively even and it's the middle that carries the disadvantage.
thin marks courses with under 120 races in the sample. Ballinrobe's numbers rest on 38 races — a hint, not a rule. And a real bias isn't automatically a profitable one: the betting market prices the famous ones in. What the verdict is honestly good for is deciding whether a race is a fair test of your horse.
Front-runners' track / Hold-up track / Fair to all styles comes from myracing.com's course-by-course guide. Unlike the draw numbers this is an experienced observer's judgement, not measured results — treat it as a steer. Where the bias depends on the ground it says so: several tracks favour the front on fast ground and swing to closers on soft. Hover for the guide's full note on any course. Lingfield is split properly: its all-weather is the one clear hold-up track in these islands; its turf leans front on fast ground.
On the straight means the race distance fits inside the course's straight track, so no bends at all — Curragh up to 8f, Naas and Navan to 6f, Cork to 7f, Down Royal to 5f. Right/left-handed, sharp (tight, nimble types) versus galloping (long-striding), and flat versus undulating come from the geegeez course guide. Irish courses only so far.
British and French races show their published closing dates from the fixture files. Irish dates are estimated — worked back from the race date using the day-counts in Campaign rules — so confirm against the HRI schedule before relying on one, especially for Classics and Group 1s, which close far earlier.
Time from your base (set under Yard & travel) — straight-line distance scaled for Irish roads. A sort order, not a satnav, and it only covers Irish tracks.
The small figure under each prize fund is the winner's share — taken as 57% of the advertised total, HRI's usual split — minus the trainer and jockey percentages set under Prize money, divided by your share count if you've set one. French funds are total allocations including breeders' premiums, so they read richer than like-for-like Irish and British money.
