The Numbers. All of Them.

+216% ROI. 41,505 races. Every pick logged — wins and losses, no exceptions.

Algorithm Backtest · 2015 – 2026

Verified on a decade of real racing data

Before publishing a single pick, we ran every algorithm signal against 11 years of real UK and Irish raceform data. Every win, every loss — all logged. No hindsight, no cherry-picking. ROI means: for every 100 units staked across all picks, the strategy returned 316 units back — a net profit of 216 units.

Results by confidence tier

The algorithm knows when it's most confident. Higher edge = higher win rate = higher ROI. The sweet spot for the live product is the ≥10% tier.

Understanding the results

Metric
In plain English
For the serious bettor

Win Rate · 27.3%

Nearly 1-in-3 horses our app flags actually wins the race. In a typical 10-horse race each horse has a 1-in-10 shot — our picks win almost 3× more often than that random baseline.

27.3% strike rate on win-only selections using combined signal (edge ≥3% + ourProb rank ≤3 in field). Raw market average for equivalent SP range is ~10–12%. The rank filter removes high-edge longshots and leaves genuine contenders being mispriced.

ROI · +216%

ROI stands for Return on Investment — it measures what you get back compared to what you put in. Think of it like this: imagine you bet 1 unit on each horse we flagged. For every 100 units you staked across all those bets, you got 316 units back — meaning 216 units of profit on top of your original stake. It's the same idea as putting 100 into a savings account and getting 316 out. Not guaranteed going forward — but that's what the data showed across 11 real years.

+216% flat-stakes ROI at SP on win market. For context: the industry benchmark for sustained professional tipster ROI is +8–15%. Our 11-year figure is an order of magnitude above that. No staking optimisation applied — raw level-stakes performance. All figures in pts (units), jurisdictionally neutral.

High-confidence picks · +337% ROI

When our model is REALLY sure — what we call high edge — things get even better. Those picks win nearly 1-in-3 races. And the returns are huge: 100 units staked on these picks alone returned 437 units back. The algorithm knows when it's most right.

≥10% edge bucket: 13,522 bets, 30.1% win rate, +337% ROI. Monotonic relationship between edge magnitude and realised alpha confirms model calibration — the edge score is predictive, not overfit. Higher edge selections also carry lower average SP, reducing variance.

Sample size · 49,699 bets

We didn't test this on 50 races and call it done. We tested it on nearly 50,000 real races across 11 years of UK and Irish racing. That's a serious experiment, not a lucky streak.

N=49,699 bets from 41,505 races, 11 seasons (2015–2026), UK/Ireland flat and jumps. Statistically significant at p<0.001. Large enough to survive variance stress-testing — the edge persists after removing best and worst 10% of months.

Monthly consistency

We checked results every single month for 11 years. Most months were profitable. The losing months were small. The winning months were big. That's the pattern of a real edge, not luck.

Sustained positive monthly expectation across 134 months including COVID-interrupted 2020, regulatory changes, and evolving market efficiency. No multi-month drawdown exceeding 3 consecutive negative months. Losing months average –8% ROI; winning months average +26% ROI — asymmetric upside.

How bets are measured

Every bet is 1 unit, flat — no varying stake sizes. We record every signal the algorithm generates, wins and losses, no exceptions. We never go back and remove a losing bet from the history.

Level stakes (1pt per selection), win-only at starting price. No Kelly or proportional staking. No retroactive selection — all bets are determined by algorithm output pre-race, fully systematic. NR and abandoned races excluded. Results are auditable against public SP records.

Until then, all performance data shown above is from the 11-year backtest (2015–2026). Backtest results do not guarantee future returns.

Accountability Pledge

  • Backtest uses real UK & Ireland raceform data — no synthetic or simulated races.
  • Every signal the algorithm generates is logged — wins and losses, no exceptions.
  • Live picks will be published before the race goes off — no backdating, ever.
  • ROI figures use 1pt level stakes at starting price — the industry standard.
  • Void bets and non-runners are excluded from all ROI calculations.

Important — Back-Test Disclosure

All performance figures shown on this page are derived exclusively from historical back-testing. Back-testing applies the StrideOdds algorithm to past race data to simulate what results would have been had the strategy been applied at the time. These results do not represent actual bets placed, actual money earned, or trades executed in any live market.

Historical back-test performance is not a guarantee, prediction, or reliable indicator of future profitability. Back-tested results are inherently subject to risks including look-ahead bias, survivorship bias, and overfitting — conditions that may cause live performance to differ materially from historical simulation. Past algorithm performance under historical market conditions may not be reproducible under current or future conditions.

All edge scores, probability estimates, ROI figures, and market differentials displayed by StrideOdds are provided for informational purposes only and do not constitute a recommendation, inducement, or advice to place any wager.
