What is Non-Runner?

How a Non-Runner Works

When a horse is entered and declared for a race, punters can place bets on it through bookmakers or exchanges. If the horse is then withdrawn — due to injury, unsuitable going, a vet inspection, or a trainer's decision — it becomes a non-runner. The timing of withdrawal matters: if it occurs before the race, standard bookmaker rules state that bets on the non-runner are void and stakes are returned in full.

However, the withdrawal also affects other runners in the race. Under Tattersalls Rule 4, the remaining horses' starting prices are adjusted upwards because there is now one fewer competitor in the market. Bookmakers apply a Rule 4 deduction to winning bets, with the percentage reduction depending on the price of the non-runner at the time of withdrawal — the shorter the price, the larger the deduction. A non-runner priced at odds-on (for example, 1/2) can trigger a deduction of up to 75p in the pound. Deduction scales are standardised but bookmakers may apply them slightly differently, so it is always worth checking the individual operator's terms.

Worked Example

Imagine a five-runner handicap where you back Horse A at 3/1 (£10 stake, potential return £40) and Horse B, a 2/1 favourite, is subsequently declared a non-runner. Because Horse B was 2/1 at the time of withdrawal, a Rule 4 deduction of 25p in the pound applies to all winning bets. If Horse A wins, your gross winnings of £30 are reduced by 25%, leaving you with £22.50 in profit plus your £10 stake returned — a total return of £32.50 rather than the original £40.

Had you backed the non-runner Horse B itself, your £10 stake would simply be refunded. The key distinction is between same-day bets, where this refund applies, and ante-post bets placed days or weeks before the race. Ante-post markets typically carry the rule that if your selection does not run for any reason, the bet is lost. This is standard practice across the industry and is disclosed in bookmakers' terms, so punters should be aware of it before committing to ante-post wagers.

Why Non-Runners Matter When Judging a Tipster

Non-runners can distort a tipster's published record if they are not handled consistently and transparently. If a tipster advises a horse at an early price and that horse subsequently becomes a non-runner, the tip should be recorded as void with no profit or loss attributed to it. Problems arise when tipsters quietly omit non-runner tips from their results, or — in the case of ante-post selections — fail to record the loss. Both practices inflate a tipster's apparent performance and mislead subscribers.

When reviewing a tipster's proofed record on a service such as TipsterCheck, check how non-runners are categorised. A reputable proofing system will log every advised tip, clearly marking non-runners as void for same-day bets and as losses for ante-post bets where the horse did not run. Pay particular attention to tipsters who specialise in ante-post or early price markets, as non-runner losses in those markets can be significant and should never be excluded from a yield or ROI calculation. Consistent, transparent treatment of non-runners is a basic measure of a tipster's integrity.
