Because the market assumes every runner will start. In reality, horses scratch, and the bet collapses. Look: you lose the whole stake, not just the place portion.
NRNB stands for “Non-Runner, No Bet”. It’s a safety net. If your selected horse doesn’t leave the gate, the bookmaker refunds the stake, as if the race never existed.
Place a standard each-way ticket: two legs, win and place. If the horse runs, the bet settles normally. If it’s a non-runner, the win leg is void and the place leg is refunded — no loss, no win.
Because the odds you see already embed a risk premium for scratches. By insisting on NRNB, you strip that premium out of the price. Here is the deal: you protect your bankroll without sacrificing potential profit.
Not every book offers NRNB on each-way tickets. Look for the ones that label it clearly, often in the bet slip description. If it’s missing, skip the race or negotiate.
Imagine a 20/1 horse with a 1/4 place. Without NRNB, the place payout is calculated on a higher implied probability, because the bookmaker assumes the horse will start. Add NRNB, and the place odds shrink slightly — your expected value rises because the risk of a total loss disappears.
Suppose you stake £10 each way on a 15/2 outsider. It gets withdrawn. With NRNB, you get back £10 for the win leg and the place leg is refunded, netting £20 returned. No NRNB? You lose the entire £20.
Step one: locate the “NRNB” tick box on the betting interface. Step two: enter your stake for both win and place. Step three: double-check that the confirmation screen shows “NRNB”. And here is why: a missing tick means you’re exposed.
Missing the NRNB option because it’s hidden under “advanced settings”. Assuming the place leg is automatically protected. Forgetting that some markets, like exotic races, don’t honor NRNB at all.
Demand NRNB, verify it, and you’ll stop bleeding money on scratched horses. It’s not a fancy strategy; it’s basic risk management. The next time you line up an each-way ticket, lock in NRNB and watch the difference.
