What 13/8 means
With fractional odds, the first number is what you win and the second is what you stake. At 13/8, every £8 you stake wins £13 in profit, and your stake is returned on top. Because you win more than you stake, it's an odds-against price: the bookmaker rates this outcome as less likely to happen than not.
It's read as "thirteen to eight".

How likely is 13/8 to win?
13/8 implies a 38.1% chance, or about 1 in 3. In other words, the bookmaker expects it to win about once in every 3 attempts. The true chance is usually a little lower than this, because bookmakers build a margin into every price.
13/8 each way
An each way bet splits your stake between a win bet and a place bet, with the place part paid at a fraction of 13/8. For a £5 each way bet (£10 in total):
| Place terms | Place odds | Returns if it wins | Returns if it places |
|---|---|---|---|
| 1/4 odds | 13/32 | £20.16 | £7.03 |
| 1/5 odds | 13/40 | £19.75 | £6.63 |
At 1/5 terms, a placed finish returns £6.63 from the £10 total stake, so it still loses £3.38 overall. Each way needs bigger prices than 13/8 for the place part to cover the bet. Work out any each way bet.
If a horse at 13/8 is withdrawn
When a horse priced at 13/8 is withdrawn after you've bet on another runner in the same race, Rule 4 takes 35p from every £1 of your winnings. It applies to bets struck at a fixed price before the withdrawal. Work out a Rule 4 deduction.
