How Often Do Winners Trade at Big Prices In-Running?
Winners drift far more often than most bettors assume. The harder question is whether a horse that blows out in-running is worth backing at the bigger price.
Anyone who has watched a race on the betting exchange knows the feeling: your horse is caught wide, the price balloons, and then it wins anyway. I wanted to know how common that really is, so I went through 129,126 winners from 129,316 Australian and New Zealand thoroughbred races, January 2020 to August 2026.
The headline is striking. 52.3% of winners traded at 10.0 or bigger at some point in-running, and 9.3% touched 100 or bigger. If you follow today's racing tips, this is useful context for those moments when a selection looks beaten at the turn. But a horse that drifts and still wins is not the same as a profitable bet, and the second half of this study is about that gap.
1Most winners touch a double-figure price in-running
This chart counts how many winners were matched at or above each price during the race. Almost all of them, 96.9%, traded at 2.0 or bigger, and 89.9% at 3.0 or bigger. By 5.0 we are still at 75.4%, and the highlighted bar shows more than half reaching 10.0.
The tail is longer than I expected. A third of winners, 33.5%, traded at 20 or bigger, 15.9% at 50 or bigger, and 0.2% were matched at the maximum of 1000. Those are horses that looked finished to somebody with money down.

| Share of 129,126 winners | |
|---|---|
| 2.0 or bigger | 96.9% |
| 3.0 or bigger | 89.9% |
| 5.0 or bigger | 75.4% |
| 10.0 or bigger | 52.3% |
| 20.0 or bigger | 33.5% |
| 50.0 or bigger | 15.9% |
| 100.0 or bigger | 9.3% |
| 1000 (maximum) | 0.2% |
What I take from this is that in-running prices measure panic as much as probability. A slow beginning, a run blocked on the rail or a leader that looks to be travelling well can push a winner's price out in seconds, and the market rarely waits to see the finish.
2Short-priced winners drift least, outsiders drift most
Raw prices flatter longer shots, so this heatmap measures drift as a multiple of each winner's starting price. Among winners that started under 2.00, 20.7% traded at twice their SP and 7.5% at five times it, across 8,867 winners. Favourites tend to be travelling well, so the market holds them.
Move down the rows and the drift grows steadily. Winners starting at 5.00-9.99 traded at twice their SP 43.7% of the time and at ten times it 9.2% of the time. For winners at 20.00 or bigger, 54.0% reached twice their SP, across 11,504 winners.

|---|---|---|---|---|
| SP under 2.00 (8,867) | 31.4% | 20.7% | 7.5% | 3.9% |
| 2.00-2.99 (18,292) | 45.0% | 32.1% | 11.7% | 6.4% |
| 3.00-4.99 (32,985) | 52.4% | 38.3% | 15.0% | 7.9% |
| 5.00-9.99 (36,980) | 59.1% | 43.7% | 16.7% | 9.2% |
| 10.00-19.99 (20,498) | 65.4% | 49.3% | 20.1% | 10.2% |
| 20.00+ (11,504) | 69.3% | 54.0% | 21.9% | 10.8% |
Trip matters a little too. In races up to 1,100 m, 38.8% of winners traded at twice their SP, against 41.9% at 1,801 m or more. Longer races give more time for a horse to look in trouble and recover, which matches what I see watching staying races unfold.
3Short drifters win less often than their price implies
Here is the betting test. I took every runner whose SP was shorter than a given price and whose in-running high reached it, then compared how often they won with the chance that price implies. At 3.0, across 48,377 runners, they won 30.1% against 33.3% implied. At 10.0, across 383,774 runners, it was 9.4% against 10.0%.
The picture changes further out. Drifters at 20.0+ won 5.1% against 5 implied, and at 50.0+ they won 2.1% against 2 implied. At the shorter end the market was right to give up on them; at the long end it gave up slightly too readily.

4Only the longest in-running drifts showed a profit
Turned into flat one-unit win bets after 5% commission, the short end loses heavily. Backing every drifter at 3.0 returned โ12.6%, at 5.0 โ11.6% and at 10.0 โ9.8%. At 20.0 the loss shrinks to โ2.7%, and it turns positive at 50.0 with +1.2% and at 100.0 with +14.3%.
Before anyone gets excited, the honest caveat. The test uses each horse's in-running high, which you only know once the race is over. Prices that big are often matched for small sums, and a horse can leap past a price without ever trading at it. Treat this as a description of the market, not a system.

| Return | |

| Back at 3.0 | โ12.6% |
| Back at 5.0 | โ11.6% |
| Back at 10.0 | โ9.8% |
| Back at 20.0 | โ2.7% |
| Back at 50.0 | +1.2% |
| Back at 100.0 | +14.3% |
My reading is simple. The market is fairly efficient when it lets a well-fancied horse drift to 3.0 or 5.0, because those horses usually are in genuine trouble. The edge, if one exists, sits in the extreme overreactions, where liquidity is thinnest and luck is loudest.
Betting notes
- Don't chase short drifters. Horses that drifted out to 3.0 won 30.1% against 33.3% implied, a โ12.6% return. A favourite that looks in trouble usually is.
- Respect a winner's comeback. With 52.3% of winners touching 10.0 or bigger, a big in-running price is not proof a horse is beaten. Avoid laying off on panic alone.
- Keep long-price stakes small. The +14.3% at 100.0 comes from hindsight highs that are often matched for small amounts. Any long-price lay-back bets should be tiny and treated as speculative.
Quick answers
How often does the winner of a horse race trade at 100 in-running?
In 129,126 Australian and New Zealand winners, 9.3% traded at 100 or bigger at some point in-running. Only 0.2% were matched at the maximum price of 1000.
Do odds-on favourites drift in-running before winning?
Less than other horses. Among winners that started under 2.00, 20.7% traded at twice their SP and 7.5% at five times it.
Is backing horses that drift out in-running profitable?
Not at shorter prices: backing drifters at 10.0 returned โ9.8% after commission. Returns only turned positive at very long prices, such as +1.2% at 50.0, and those figures rely on prices known in hindsight.
