Won After Trading 20.00+ In-Running: What Happens Next Start?

Every racegoer has watched one: a horse that looked beaten at the turn, traded at a silly price in-running, then got up on the line. I wanted to know whether those winners are flattered by the result, and whether the market treats them as flattered too. This study covers 97,258 next starts by last-start winners in Australian and New Zealand flat racing, from January 2021 to August 2026.

The answer is clear. Winners that traded at 20.00 or bigger in-running won only 11.4% next start, against 27.9% for winners that never traded above 2.00. But the starting price had already allowed for it almost exactly. The gap between the two groups is real, yet it is not a gap you can bet. That is the kind of trap I try to avoid on my free racing tips page.

Branch ABigger in-running drifts mean weaker next-start win rates

Each row groups last-start winners by the biggest price they traded at during that win, then sets their next-start win rate against the chance implied by their SP. The pattern slopes steadily down. Horses never above 2.00 won 27.9% next start, the 5.00-9.99 group won 16.9%, the 10.00-19.99 group won 14.1%, and the 20.00 or bigger group won 11.4%.

Now look at how close each pair of dots sits. The 20.00 or bigger group was priced at 11.5% and won 11.4%. The dominant winners were priced at 28.5% and won 27.9%. No row shows a mispricing worth chasing.

What I take from this: the in-running high is a useful reading of how hard a horse had to work, and the market reads it too. Treat a lucky-looking win as a caution, not as a hidden edge.

Branch BLucky winners fall out of the places next time

This is where my each-way habits make me look harder. Winners that never traded above 2.00 won 27.9% next start, placed without winning 27.8% and were unplaced 44.3%. That is a solid platform for a place bet, because more than half of them finished in the frame.

At the other end, winners that traded at 20.00 or bigger placed only 21.7% and were unplaced 66.9%. Their place rate drops as well as their win rate, so the bigger price does not buy you a safer each-way position. Most of these horses run down the field next time.

Branch CShort-priced dominant winners returned the worst losses

Returns are flat one-unit bets at SP after a 5% commission on winnings. Every group lost money. The impressive winners that never traded above 2.00 returned −14.5%, worse than the −7.6% for all last-start winners together. The horses that came from a long way back returned −8.0%.

The narrowest loss came from the 5.00-9.99 group at −4.9%, while the 10.00-19.99 group returned −10.4%. That up-and-down shape is a warning in itself. A true edge would usually build smoothly across the groups, not bounce about.

My main caveat sits here: in-running highs are known only once the race is over, a horse can jump past a price without trading at it, and returns within a few points of zero can occur by chance. None of this is a betting system.

Branch DMeasured against SP, the drift tells the same story

A drift to 20.00 means one thing for an outsider and something quite different for a favourite. So this table measures the in-running high as a multiple of the horse's own SP. Winners that never went above their SP won 16.0% next start and returned −11.9%. Winners that drifted past 5 times their SP won 13.0% against 13.1% priced, returning −6.1%.

The median next-start SP rises from 8.24 for the never-drifted group to 10.30 for the biggest drifters. The market pushes these horses out, and by about the right amount. The 1.5-2× SP group returned −2.9%, which is the closest to break-even in the study, but I would not build anything on a figure that small.
