What 66/1 means
With fractional odds, the first number is what you win and the second is what you stake. At 66/1, every £1 you stake wins £66 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 "sixty-six to one".

How likely is 66/1 to win?
66/1 implies a 1.5% chance, or about 1 in 67. In other words, the bookmaker expects it to win about once in every 67 attempts. The true chance is usually a little lower than this, because bookmakers build a margin into every price.
66/1 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 66/1. For a £5 each way bet (£10 in total):
| Place terms | Place odds | Returns if it wins | Returns if it places |
|---|---|---|---|
| 1/4 odds | 33/2 | £422.50 | £87.50 |
| 1/5 odds | 66/5 | £406.00 | £71.00 |
At 1/5 terms, a placed finish alone returns £71.00 from the £10 total stake, so the place part covers the whole bet with £61.00 to spare. Work out any each way bet.
If a horse at 66/1 is withdrawn
A horse priced at 66/1 being withdrawn doesn't trigger a Rule 4 deduction. The scale only applies when the non-runner was 14/1 or shorter. Work out a Rule 4 deduction.
