What is Non-Runner No Bet (NRNB)?

How Non-Runner No Bet Works

In standard ante-post betting, you accept the risk that if your selection is withdrawn before the race, your stake is lost. This is the default position and is clearly stated in most bookmakers' ante-post rules. NRNB removes that specific risk: if the horse you backed does not line up on raceday, the bookmaker refunds your stake in full rather than settling the bet as a loser.

NRNB is a concession, meaning bookmakers choose to offer it rather than being obliged to do so. It tends to appear on markets for major meetings — Cheltenham Festival, Royal Ascot, and the Grand National being typical examples — and is usually available for a limited window in the weeks or days before the race. Crucially, the precise terms and the timing of when NRNB applies vary from bookmaker to bookmaker. One firm may offer NRNB up to 48 hours before the off; another may apply it only from a certain date. Always read the specific promotion terms before placing your bet.

Worked Example

Suppose you back a horse ante-post for the Cheltenham Gold Cup at 10/1, staking £20, with a bookmaker that has declared NRNB on the market. The horse is subsequently ruled out through injury and does not run. Under NRNB, your £20 stake is returned in full. Without NRNB, that same bet would be settled as a loser and your £20 would be gone, regardless of whether the rest of the field ran normally.

It is worth noting that NRNB only covers the non-runner scenario. If your horse runs and loses, you lose your stake as normal. If it runs and wins, you collect £20 × 10 = £200 in winnings plus your £20 stake back, totalling £220. NRNB does not affect the odds you were given or change the settlement of any other outcome — it purely acts as a safety net against a withdrawal.

Why NRNB Matters When Following or Judging a Tipster

When a tipster advises an ante-post selection, whether or not NRNB was available at their advised odds is material information. A tip placed with NRNB carries less risk than the same bet without it, because a non-runner returns stakes rather than registering as a full losing point. If a tipster's proofed record counts non-runners as void rather than losses, but followers placed the same bets without NRNB and lost their stakes, there is a meaningful gap between recorded performance and real-world results.

When assessing a tipster's ante-post record, check how non-runners are treated in their results log. Transparent services will note whether NRNB was in place and will record bets accordingly. If a tipster regularly targets ante-post markets without specifying whether NRNB applies, that is a red flag worth noting — particularly over a small sample size, where a handful of non-runners treated differently can distort yield and profit-in-points figures significantly.
